| Which resistors to use for KT88 output tubes I've never tried Mundorf resistors. The only one's I've seen are the large 10 watt types.On the grid carbon composite types are best because they help in suppressing parasitic oscillations. Even if the grid drifts a little over time it won't hurt ... | |
| Which resistors to use for KT88 output tubes For the 10 ohm use Mills, for the 100 ohm 1 watt nothing special needed. These should be coming from the output transformer. The 2.2k grid resistors are more critical. I like Riken but sources for these are about dried-up. Carbon composite resisto... | |
| Prima Luna amplifier mains cap upgrade? It should work fine if you have the room. I prefer to use poly caps when possible. Another interesting candidate would be the new Wima cap from Mouser 505-DCP6-330/1500/10 | |
| Counterpoint - Alta Vista - Mike Elliott Yes I've learn many things from reading his work. Here is some more information about his business closure.http://www.whatsbestforum.com/showthread.php?6805-Alta-Vista-Audio-closing-it-s-doors | |
| Nad M3? Need amp for Vandersteen 3 $3,000 budget McCormack Amps are a good match. | |
| Tweaking the caps of the Dared SL-2000A The Auricaps are nice capacitors. I think partsconnexion has them at 40% off now. You may want to try the input caps first. They are smaller and will be cheaper. The output caps look larger and will be more expensive. Also you will need 4 of them.... | |
| Tweaking the caps of the Dared SL-2000A There are two input caps you could change first. There is one on each side of the volume pot. Change with the same value that is in there now. Then you can look at the four yellow caps behind them. They are the ones that look like yellow boxes. Th... | |
| 5751 for 12AT7 for Dared SL-2000A I don't think that's a very good idea. Different tubes and different operating points. Will it blow up? No it should be okay. But I think you should stick with one of the 12at7 variants. There are some nice tubes available in the ECC81 family. Jus... | |
| Jolida 502 KT120 tube swapping The resistors I mentioned was not part of the upgrade. I'm sorry I was just trying to help you improve the amp. I would be careful putting the KT120's in this amp. First they draw more current and this could hurt the power transformer with extende... | |
| Jolida 502 KT120 tube swapping The Jolida is basically a Mullard 5-20 design with different tubes. Don't spend the money on the tubes. IMHO. Replace the 15k resistor in the 12at7 tail with a Compact Cascode current source kit from http://www.kandkaudio.com/accessories.html Then... | |
| Blown resistors CAT JL2 mk2 Anyway to post a picture of the resistors that are not burned? Or at least give a physical description. | |
| Volume Pot Upgraqde A stepped attenuator would be a nice choice. If it won't fit, look at a TKD pot. | |
| AC CABLES a little help I think you should consider Neotech NEP-3002 or NEP-3003. Buy a couple of meters and a couple connectors and you have a nice power cord. I use the 3002 on my amp and the 3003 on my Cd player. Partsconnexion, Soniccraft and VH-audio all sell it. | |
| Jolida 502B correct tube allocation Don't get me wrong. I really like NOS tubes. I have a nice hoard to prove it. But you mentioned that shipping and customs duties where high in your country. It can get very expensive trying NOS. You should have some tube guys around. Don't give up... | |
| Jolida 502B correct tube allocation Edoll, I'm not sure what tubes you are refering too? Anyway be careful getting on the NOS tube rolling wagon. Expensive and you may be dissapointed. You may be perfectly happy with some new tubes like JJ or EH and save a lot of money. You may star... |
