Phono Preamp Tube Rush

dammmmmm audiophiles!!!!!. Please take this out of my mind.

I didn’t know about this, have never heard it, and now it is in my mind that I just haven’t been paying attention. I’ll listen tonight, better not hear anything.

I had my new dual arm tt CRANKED last night. 3 guitarists, Euryhmics, Michael Jackson Thriller, test record musical/imaging tracks, Stereo, Mono, ....

I heard some static between tracks, nothing else. I gotta get a fresh copy of that Eurythmics album, perhaps Valentine’s Day.

Fisher 80Z Mono Blocks; Fisher 500C; Fisher 800 (500c + am); now wonderful McIntosh mx110z (2 MM Phono inputs); My friends never push their system like I do, their speakers are not as efficient as mine, over 100db/1w/1m.
...............................

Is this perhaps related to volume factors?

1. efficient speakers get loud before excess power needed by inefficient speakers, thus the ’rush’ doesn’t occur. Inefficient speakers get you into the 'rush' zone.

2. Low Output MC Cartridges, require more volume than MM cartridges that I use.

3. the combination of inefficient speakers and low output cartridges.

..............................

Thanks for clarifying.

I am fundamentally opposed to Moving Coil because of the extra amplification involved. I don't even want to hear a fabulous one, I don't want to go down that rabbit hole.

My Preamp, 55 years old, when direct to the integrated amp's bypass pre-in, then gets all volume from the preamp. In that use, I start to get noise, hum, around 11 o'clock position. It's just above my preferred max. so luckily I stay just below any noise.

I've hosed the internals with contact cleaner, no noises, but hum begins. I've tested my 17 tubes twice, but, to be sure, I ought to try some new ones before I spend some money switching caps .... Oh I'm keeping it, even if it needs spending some money.

Using my preamp into a line input, volume is created elsewhere, no hum from pre-amp even when system cranked. 

So, below my typically desired volume, in any configuration, this 55 year old pre-amp is noiseless. 

btw, The preamps FM Tuner, as they say: with a good signal, is superb.

the tube amp, Cayin AT-88, still sold, is dead quiet. Mine is early version with 16 ohm taps, sadly bias adjust is internal.

Still never heard tube rush.

btw, McIntosh does not service these, has no parts, and only referred me to 1 local service shop. He has a 12 week cycle for new work. Says he only needs 2-3 hrs work, probably not mush $ in parts. So, I say, put me in the schedule 4 months from now. No, I can't keep track like that. Bring it here, wait 12 weeks till I get to it.

Thanks for the suggestions,

What else do you have in that Vintage System? Inheriting my wealthy uncle's system is how I got hooked.

I visit my friend Bill 15 minutes from Binghamton every spring, we photograph waterfalls with plenty of water.

Last year I pre-arranged with McIntosh, to check out my SS amp MC2250 and SS Preamp C28. I was going to sell them.

dropped off Thursday before noon, picked up Monday afternoon. Good people. btw, that place is HUGE!

Sold em, bought the mx110z tube tuner/preamp and a Cayin A88T Tube amp, wonderful together. I need 16ohm tap, this early Cayin has them, but, bias adjust is inside.

Anyway, McIntosh said no, mx110z too old, no parts, ... They are making me a new mx110z factory box, $55. and shipping it to me free. 

I figure, I'm not ever parting with it, why not have it checked out, probably will need a box.

Audio Classics is a few miles closer to my friend than they are. I'll call them and see what they say.

Sorry to OP for my off topic trip.
