| Jolida 502B correct tube allocation From the far left. AT7 then AX7 another AX7 and then on the far right side AT7. Two center tubes are AX7's. | |
| Looking for brighter tubes You should consider changing the four.22uf coupling capacitors and the two .47 capacitors. They are made in China by CBB and they are dirt cheap. That is why they use them. Not for their sound. Good for their price but easily outdone. Siemens E81C... | |
| 6922/6n1p sub with a 6cg7 6922 can be substituted with a 6N23P. The 6N1P has a plate resistance that is almost three times that of a 6922. You would most likely need to decrease the resistance of your cathode resistor to get optimum performance. Also be aware that both the... | |
| Jan GE 6cG7 what other tube recommendations I find the RCA black plate to be good all around. Well balanced and good extension on top and bottom. That said the difference between the two different RCA's, Sylvania's and GE's is not that great. They are all fine tubes.I have not tried the Ray... | |
| Triangle Cellius SE Modifications? You might want to take a look at this site. http://www.humblehomemadehifi.com/Cap.htmlTony has done a lot of capacitor comparisons with his speakers. I may be inclined to take off the super-tweeter and try replacing the coupling caps in the Prima ... | |
| Tube heaters: Heater's can use either AC or DC. Most amplifiers use AC because it is convenient to use for the small tubes as well as the power tubes. Preamp will have both. DC is quieter but if the AC is done correctly it works well. Some like it better.Some a... | |
| Jan GE 6cG7 what other tube recommendations I did read somewhere about the Amperex being a re-branded GE or Sylvania but I am by no means an authority on the subject. As Atmashere said all the vintage 6CG7 tubes are good. I just like the sound of this tube. It's basically a miniature 6SN7.... | |
| Jan GE 6cG7 what other tube recommendations I have never used the EI so I can't give comparisons to those. But I have the GE, Sylvania, RCA clear tops and chrome tops. Actually all sound very good to me. I think the RCA chrome tops are my favorite. I bought mine on ebay. | |
| Jolida jd-502p They work fine. Will you like them better? Give them a try. | |
| long speaker cables or IC's for budget system The benefits you gain from moving the stereo from the middle of your speakers may be worth it. I would say it is sure worth a try. Shorter speaker cables and long interconnects would be better. "IMHO" Beside $150 doesn't leave much choice for spea... | |
| One of my Tubes on the Jolida 301A flickers You question is not clear to me? When you change the tube does the problem move with the tube? Example V1 flickers and is distorted and you move that tube to say the V5 position. Does the problem move to the V5 position or does the V1 position sti... | |
| Shipping to Norway? I actually bought my speakers direct from Vandersteen and shipping through the airlines was their suggestion. I've been listening to them for almost four years without an issue. It is not easy to ship overseas via surface mail now. "try" USPS sto... | |
| Shipping to Norway? If it's possible to get the amp delivered to the airlines that could be another option. I had my Vandersteen's sent to the airport near my home in China. Check with the airlines that fly to the U.S. I'm not sure if this will be any easier or chea... | |
| 6NS7 tubes or substitutes for gain reduction? Check with your manufacturer before changing the tube. You can put any brand of 6SN7 without issue. But most circuits require changing some resistors to set the operating points of the tube if you change the tube number. Some tube are even wired ... | |
| My first tube preamp Manley jumbo shrimp If you still have the EH 12at7's you may want to try something different. I personally like German ECC81's but others will have different opinions. Tubes do make a difference. Try the input tubes first. |
