Elliott, even if the pin out is the same and the operating characteristics are very close it's always best to look at the filament current draw on the data sheets and compare. I would suspect being a larger octal tube that there is a good chance it will load the transformer more. Not worth risking it unless you know the exact specs on the transformer and there is plenty of reserve.

6N23 = 6922, etc. They are the same tube so far as I can tell. |
lewm,
thanks for looking this up, very helpful.
I agree, thousands of hours, and, my office system gets less work than the main system. On the other hand, it could arrive smashed.
It was a 'what if?' and, my recent lousy sounding 6SL7's for my Cayin is a warning about spending money for the wrong substitute. I got lucky, my 2nd choice was a winner.
If it sounds great, a direct replacement may avoid a tube chase. |
Did some research for you. 6DJ8/6922 are equivalents. This is a whole family of tubes sold under different alphanumeric designations. You could hardly have a wider choice. Go to Tubes Store for example. Oy. |
Elliot, you need not fret about the availability or lack of 6N23 tubes in the US or the shipping expense from Russia. I’m sure there are some very suitable substitutes that are readily available here. Moreover you have thousands of hours of listening ahead of you before you even have to solve this non-problem. That’s assuming you like the SQ of the Russian preamp. If you don’t, you’ll be selling it before the tubes wear out. |
Seamail shipping cost nothing compared to EMS. But seamail is 3 month minimum.
Airmail post is also cheap, but you must wait longer.
I have no idea why do you compare China and Russia? Almost everything is made in China and almost nothing is made in Russia nowadays.
Chinese products cost nothing and shipping often is free (don’t know how they can make a profit :)) |

keyword of my hope is: "re-surfaces".
Perhaps, it seems like you are saying: there never was a low priced method from Russia; never close to as low as China was and still is able to accomplish. Past: better time, not better price.
"russian 6N23P-EV in the second cascade"
Knowing this, the preamp maker should have offered spare(s) at a low cost prior to shipping the unit.
If China had 6N23P-EV’s in stock, how much do you guess they would charge to ship a pair?
I shake my head at the low shipping charges they offer.

There is only one regular flight to USA from Russia and it’s Moscow - New York.
Do you know that all boarders with EU closed for Russians? The US is open, but how many flight do you expect in this situation? 90% of the flight to any destination are canceled long time ago.
It’s true than EMS is not cheap, but it’s Express, it was 5 days estimate before covid, now there is NO estimate delivery time to USA, but, in my own experience, anything from 7 days to 30 days is normal, anything from 30 to 60 days is also OK (just bad luck). If it’s more than 60 days then you can only open paypal claim, your seller will never get refund from the shipping company (insurance for full value is impossible), except for shipping cost, but paypal will refund you withing 2 weeks 100%.
Why do you think shipping from Russia to USA must be cheap, do you know USPS international shipping rates?
For example: to ship one LP from USA to Russia cost $25 minimum and it’s not even Express mail (not even priority).
When you pay $40 or even $100 for an amp shipped from Russia to USA with EMS Express it’s fair price! Try to calculate same weight on usps.com for shipping to Russia.
Russia is not China, so your analogy with shipping from China is irrelevant.

chackster,
Interesting, thanks for the info, I thought you might be interested in his reply about Boxberry.
You know I am patient, I was just curious if they got any more info than 'In Transit' on their end.
Occasionally I order things direct from China, thru eBay, Wish ... stuff comes rather quickly, very little money, sometimes free shipping built into an already low price.
I am hoping an inexpensive shipping method from Russia re-surfaces so I can buy the Russian tube the preamp uses rather than substitute. Now they tell me the minimum price for a small parcel is $40. USD.
|
There is nothing about delivery to USA with Boxberry on their site. They do not ship to USA. The best way to ship from Russia to USA is Russian Post (EMS Express). However, if you’re not a sender you can’t make any claim. You can only wait. If it was shipped on March 1st then you will get it soon. Don’t waste your time sending requests to Russian Post, it’s worthless. Even if your seller (as a shipper) will proceed with claim it will take over 90 days to investigate the case. EMS do not provide an insurance anyway. If your parcel is lost - it’s lost, compensation for shipping only. Check this tracking system: www.trackitonline.ru |

I just wrote to the seller, he gets what I get, simply 'in transit' since march 1st.
He mentioned Boxberry, anyone know anything about them?
"For my part, I try to constantly send requests to the Russian Post. They answer - "the package is being delivered, please wait."
Just this week, another inexpensive way to send parcels to the United States appeared - the Boxberry company. Unfortunately, a couple of months ago, this company did not send parcels abroad yet."

Elliot has your preamp arrived from Russia yet?

i'll quote lewm
"The BDP105 and the 205 are possibly the best DVD players ever made that are not astronomically expensive".
that's my goal with anything. |
elliott,
I'm sure that it sounds perfectly fine to you and your friend. I'm just saying that if you compare it to a really fine player, it has an artificial and electronic signature to it. Hey, they didn't cost a fortune, so you can't expect too much. |
I did that. It never occurred to me: he doesn't have any current listings, so nothing came up.
I was looking to find his profile: approval rating, sales history, evidently has sold 360 items,
nothing came up.

Re: "How do you search for a seller on eBay..."
Upper right on eBay page, click "Advanced" to the right of the Search button, and scroll down to the Sellers section. Check the "Only show items from:" and "Specific sellers.." boxes and type the seller’s user id in the window beside the include/exclude drop-down. Then click the Search button. |
just bought a BDP-105 for $900.

I asked seller to confirm very little use of laser
" Hi Elliott? I am GUARANTEEING that this unit Looks, Plays, and Sounds like brand new! I have played 5cd’s, NO dvd’s, and have only used it for streaming music from my computer. I did make a brief video with it powered up & playing---but it would not upload. If you decide to purchase, it will be blatantly obvious how fresh and new this is just by unpacking the contents.....I would put aside any Laser issue fears with this model, it is like factory new---5cd = 5hrs (approx) on the Laser & all other use via USB from my computer!
Regards,Alexander.

lewm, thanks for your advice,
I checked out the 105, some very good reviews, in my budget.
I don't need the Darbee version which was a video upgrade.
One thing I like about the BDP-105 is that replacement lasers are readily available.
One thing I don't like about the BDP-105 is that there are MANY people selling replacement lasers.
I've got my eye on two, both original owners, excellent condition. Let's see what answers they can give me about how much work the laser has done.

Reviewers seem to disagree with you, as well as lewm.
I had an early Oppo, used only for video. Read somewhere that it had well respected sound. My Onkyo DX-7500 was still my CD player then.
For fun, moved the Oppo into the sound system, it sounded very good. I gave it to my golden eared friend, he still loves it.
I got a more video advanced blu-ray player, now using it for CD's in the garage sound system. Small HT, went fully cooperating sony tv/avr/blu-ray, 1 remote talks to all. |
I own a BDP83SE (from the estate of a friend), an Oppo BDP105, a Sony 2400ES, and an Ayre C5Xe-mp. These are all at least "good" CDPs, but I like the Ayre and the BDP105 best, with an edge to the Ayre. The BDP105 and the 205 are possibly the best DVD players ever made that are not astronomically expensive. I actually hesitate to rate the Sony, as I rarely use it for listening, and my wife uses the BDP83SE for movies most of the time. The Ayre has a possible issue if you use it to feed electrically unstable downstream components. For max audio quality, it does not have a low pass filter on its output. Thus it puts out some "noise" at very high frequencies, like 250kHz. This only helps the audio, but it can upset any downstream components that have a tendency to oscillate. The Sony and I presume the Oppo devices do have such filters.
|
Not sure what your budget is, but I'm sure you can do better than an Oppo. They're not very good sounding. |
Nada, Nyet, Nope. It will be a nice surprise.
Meanwhile, I decided to try and find a reasonably priced CD player that is audibly superior to my existing Sony.
Found and bought an Oppo BDP-83SE (special audio edition). Sadly, the laser mechanism was shot, 'unknown disc' .. Evidently a common problem. I just dropped it off yesterday pre-paid return shipping for full refund when received.
Been looking at:
Oppo UDP-205 (dual processors)
Onkyo C-7000R (dual processors)
*my first player was Onkyo DX-7500, dual matched burr brown processors, wonderful but got so drawer wouldn't open. I now realize I should have had it fixed, but it annoyed me (I couldn't fix it myself) and was very large.
Pioneer UDP-LX500, interesting audio options.
Denon DCD-800NE
Sony UBP-X1100ES

Well? Well?
Any new news yet? |
Gosh, cmariner1.
How interesting and insightful!
And on only your second post. One can but hope all your future remarks will be as profound... |

I wanted vintage, small, tubes, but, this SS caught my attention. https://www.audiogon.com/listings/lisa99gf-marantz-sc-7-solid-stateloaded with features (except auto-loudness for low volume listening). see front and back. the built-in mc variable loading a big draw, and I like my L-Pads, for speakers with no adjustments, the 3 band tone control should perk or tame for any space live or dead. see bypass ye purists!
|
True. There's just something home-brew about it that's charming. |
roxy54
IF it sounds good, yes, a fun quirk,
but if I knew, that doesn't give a lot of confidence. They say they have units all over the world. They have had time to notice themselves. |
Product of China, not Russia
|
Why would you have passed it up just for a misspelling? You know that it's not a product of a large multinational corporation, so it's not a big surprise. I think it's actually interesting. Something to show friends and guests. |
stereo54,644 posts02-13-2021 7:12pm"I noticed they spelled Vacuum tubes as vacuuum tubes on the preamp".
Funny, I just got what you wrote, 'on the unit'. My mind thought/assumed 'in the text', and the USPS change grabbed my attention. IF I had noticed that I would have passed it up. (how the heck did I, and many miss that?) Sometimes/often, we see what we want to see, we hear what we want to hear. |

Thanks. Good for Elliott.

EMS is Air Mail only.
Custom (export) inspection is just scan of the box, takes 5 min.
The problem is available flight to USA.
My recent parcels to L.A. or Miami took 7 days with EMS (very quick) |
But that means it is only just cleared to leave Russia (which is ridiculous), how? By boat? In that case, having it by your 75th may be realistic. By air? Then maybe 2-3 weeks.
|
cleared Russian Customs easily, in transit since 3-1-21 |
|
Someone already posted that video a couple of weeks ago on another thread. Looks like Robert Plant. |
|
Mine rotted, I replaced the surround, it sounds very nice here in my office. |
and when my old Velodyne sub's surround rotted, I knew I could do with confidence.
rotten? I believed that the suspensions of that brand were indestructible with the passage of time! |
OK. I am not that, either.
|
Interior Designer, not Decorator! I am more like an un-licensed Architect. |
Well, you don’t own it, so there is no controversy. I just said what I would do, because I am not an interior decorator. |
I agree. There is plenty of ventilation and the case is too beautiful |
I agree removing cases on many tube units, however:
That design has all the tubes mounted in a row out of the back, similar to that McIntosh, except, Luxman wisely put the row of tubes up high, above the in/out cables. It’s got a decent vented grille, no way I would remove that Rosewood case which is a major draw for me. |
