| Best 6550's for ARC VT-100 MK3 amp- SED; Tungsol?? The winged C 6550's are stock on the VT-100 MK3. Since that amp was voiced with the winged C thats the tube I would go with. G. Garfield | |
| Marantz 10b repair Ive worked on a few 10B's and I would send it back to AC. BTW that tuner was designed by Dick Sequerra. Every tuner that came off the assembly line had to be trouble shot. No 2 are alike. I received this info. from a 2 hr. conversation with the la... | |
| New Tubes- Need Burn-In? Bartokfan...KT-88's and KT-90's are two very different tubes. Compare the KT-88 with the winged C 6550 insted. KT-90's to my ear are much more punchy and a bit more agressive then the winged C 6550. Usually KT-90's have a bit more output as well. ... | |
| set vs otl, which is the most musical atma-sphere's used to have fans in them for cooling. They do run hot but i could name a few non otl amps that ran hot too. With otl amps its more a function of what type of output tube there using and how their biasing the tube. Generally speaking... | |
| EL34 Integrated How about a Dyna stereo 70 with an input volume control. BTW to Ponnie...tube amps are voltage amplifiers, transistor amps are current amplifiers. Sometimes tube amps with huge power supplies can also act like current amplifiers too. If you are ru... | |
| set vs otl, which is the most musical I would agree with Thomasheisig with regard to the Atmas. I once heard these amps with the top of the line full range Sound Lab Electrostats and almost fell off my chair. The sound was nothing short of breathtaking. The problem I have with SET amp... | |
| ARC LS1, LS2, LS3 , or LS7, which to buy? If you are looking for a vacuume tube sound your not going to find it in the LS preamps u mentioned, since they are hybrid designs. I used to own a SP-6B and liked it alot, although working on it is a rather big chore. The 6B has a lumpy frequency... | |
| Kimber vs Jensen coupling caps in Cary amps This is one of those questions where there is no right answer. Since coup. caps are a must in tube products, using them is something like a tone control. The only way to know for sure is to try them, let them break in, and see if u like them. If y... | |
| ARC Ref 3 or VTL 6.5? The ARC is a stunningly good preamp! On top of that, I have found that VTL has awful customer service. G. Garfield | |
| Best Solder?? I use WBT solder for my speaker prototypes. Works great ,sounds great, and has a low melting point so it cools off looking nice and shiney, i.e. no cold solder joints. G. Garfield | |
| Replacing OA2 tubes with Zenier Diodes in Preamp The other advantage in keeping the 0A2/6EM7 combination is the fact that they act as a soft start circuit. By replacing the 0A2's with a zener diode you will put voltage directly on the 6EM7 before it's had a chance to start conducting, usually 10... | |
| Hammond transformer vibrates......ALOT You might also try lifting the transformer off the chassis and isolating it from the chassis using rubber feet or something similar. The problem is the transformer is also vibrating the chassis. You might also just replace the transformer because ... |
