RM 200 with KT 120 Tubes Sbfx the KT-120 is not an exact replacement as it pulls a bit more heater current per tube. Roger is probably trying to do some long term reliability tests just to make sure it's ok to use. | |
Maintenance for Tube Preamps I would stay away from Cramolin. It does tend to keep cleaning even when you don't want it to and can leave crud behind. I use pro gold but again if it isn't broke don't fix it. Changes can be made sonically to the preamp by replacing coupling cap... | |
Anyone replaced Fuse with Circuit Breaker? I agree, bad idea. Breakers take too long to trip. | |
Audio Research VT100 tube replacement Siffled, isn't there an ARC warranty repair place in your city? Or are you in MN? | |
Audio Research VT100 tube replacement In another thread I commented that when I service an ARC product I get my tubes from ARC. It saves a lot of grief. It's also a good insurance policy because if an ARC tube goes out and causes damage, ARC will cover the repair costs within the firs... | |
Good tube amp kit for sale these days Bob Latino's stuff looks very interesting. The only question I have is regarding the twist lock lytic power supply cap. Since there's no heat shield around that part, they usually start leaking in short order. Has anyone replaced it with the Curci... | |
ARC VT100 with KT-120 tubes ? Farobari I try and tell my ARC customers that all the time. ARC tubes are more expensive but well worth it, especially if you want to get your amp up and running quickly. I also recommend factory trained technicians do this because you are dealing... | |
Bandwidth question? Orpheus10. That's all part of this. Sine waves don't really tell you much about the bandwidth of an amp or preamp since all your getting is the fundamental frequency without the harmonics. I tend to look at square waves. That tells me a lot about ... | |
Bandwidth question? I have never been a big fan on Mhz frequency response especially in an amplifier. Having a bandwidth that high can cause major problems including parasitic oscillation, rf interference etc. This can cause the top end to sound hard, grainy, and str... | |
ARC VT100 with KT-120 tubes ? It is possible that the KT-120's are running cooler because the plate of the tube is much larger. Therefore, there is a greater area for heat dissipation and less chance of a hot spot. There are also heat sinks on the plate structure as well, maki... | |
Audio Research VT200 Biasing Schematic ETC. Re VT-100 mkl and mkll. I prefer to use 2 volt meters. Still kind of a pain. I suggest people get some grabber test leads as it's safer rather then just using probes. | |
First Tube Amp: Advice? Keep spare tubes on hand? Xti16 I couldn't agree more. Running an output tube on a machine for 10-15 mins. is a waste of time. Many output tubes require 24 hrs. for the innards to stabilize. I just got done installing new output EL-34's in a Conrad Johnson Amp. And sure en... | |
VTL Compact 80 Issue Don't try sticking another tube in there as you could damage any tube you try putting in that spot until you determine what the problem is and fix it. I no longer repair VTL's. | |
Audio Research SP16 vs SP3A1 and SP3C The advantage of the SP-3A1 and SP3C are of course the tone controls if you require them. Hands down the SP-3C sounds superior to the SP-3A1 in tonality as well as quietness, detail etc. Basically there was no downside to the power supply update. ... | |
ARC VS-115 vs ARC Ref-110 As I said in an earlier post. It's worth the wait. The Ref150 is the way to go. |
