| Power blackouts - problem for tube amp & speakers With most tube amps its no worries at all. | |
| Class A or AB amp for JBL S4700 speakers You might want to get a sound pressure level meter so you can be sure both amps are playing at the same level. First Watt amps don't make a lot of power relatively speaking. My money is on the First Watt as being the better sounding amp within its... | |
| How do you know when to replace tubes Heck, almost any triode power amp can log 10,000 hours on the power tubes, the exception being the 6C33. We had one of our amps log 22,000 hours on the power tubes before we finally had to replace one (there were 16 power tubes in that amp, FWIW...). | |
| Tube Bias issue. If the bias is OK in triode mode and without a preamp attached, then we can assume that it is not noise coming into the amp from the preamp.We can also assume that its likely that its not noisy driver tubes.This leaves the switching means itself. ... | |
| Tube buffer ??? How would you use the tube buffer to help your phono sound?? This does not make sense to me. | |
| How do you know when to replace tubes A tube tester is always a good way to tell.In our gear, it tends to move towards a sleepy sound if the tubes are shot. | |
| Looking for Tube Pre-Amp Recommendations Zd542, We've had that model of CJ preamp come through here for repair in the past. It was pretty quiet- I don't see noise as being an issue with Duke's speakers. | |
| tube pre amp and Krell FPB 600 ^^Even if you have solid state you can get a thump. The reason you don't is your preamp has an automatic mute.Many tube preamps do nowadays too. | |
| Looking for Tube Pre-Amp Recommendations Based on the specs I am seeing online for the speaker, I think your bottleneck is the interface between the speakers and the amp. You are making the amp do a lot of work to drive the speakers to a reasonable volume. The speakers are 4 ohms, which ... | |
| I need a couple suggestions for a preamp Looks like you have a balanced input.There are balanced tube preamps, the only vintage one being a preamp made by us, the MP-1 (which we still make). I don't see specs on the amp website, which will be something you might want to know depending on... | |
| tube pre amp and Krell FPB 600 Salectric, Historically tube preamps have been in use with solid state amps for **decades**! Solid state amps by their very nature have to have a protection circuit, and there aren't any warmup thumps that a tube preamp can make that can damage th... | |
| tube pre amp and Krell FPB 600 The input of the Krell is direct-coupled (no coupling caps). This is why they are 'concerned'. However, the claim that tube preamps put out DC is ridiculous. They no more do that than solid state. | |
| Class A or AB amp for JBL S4700 speakers In other words, it is class AB.Class A amplifiers are class A right to full output. | |
| I'm in a preamp pickle: ARC Ref 1 VS CJ 17LS I would go with the CJ. The ARC has the drier house sound that is part of the ARC legacy. The warmer sound of the CJ will complement your system nicely. | |
| Super-sensitive volume controls - remedy? Really the best way to do it right is to send the CDP or DAC back to the manufacturer and ask that they lower the output. Its not that hard for them to do it and usually the result is better sound in addition to less troubles. We have tried buildi... |
