Tube Amp Archive

Thanks Roe that's exactly what I was looking for. Sorry I've been busy and haven't checked back everyday. To answer the questions on why I asked, the practical use here is I'm putting together a 3 channel schematic with one of them being a Plexi channel; in this case I'm only going to use one triode...

Warming of the tone, fills it out a bit. It's less "in your face", which sometimes is a good thing.

Just so i'm clear, when we're talking about a non-jumpered situation any bleed through from the unused channel is sourcing from parasitic capacitances within the tube and it's getting through because the pot wiper may not go all the way to 0ohm?

If you're plugged into a Bright input on a plexi without jumpering, is the bleeding between channels just about the fact that there's signal flowing through the Normal channel mixer resistor to the Volume II pot? Is it correct that I think that when I turn up Volume II, i'm increasing the resistance...

Yes it does. From what I've read the insertion loss with the vactrol shouldn't be too much to make it a bad choice but nonetheless minimizing the insertion loss would be a plus.

It's about switching the audio signal path in a multi channel amp. I guess I'm now digging up some data sheets and trying to figure out the best on paper or at least what I think is the best.

Hi, I'm buying parts for my first amp with channel switching. I'm trying to decide on buying vactrols vs relays. Can we discuss the advantages and disadvantages of each and what your current preferences are? My thoughts without having tried both is that relays are cheaper and simpler to implement bu...
