Good point, and it's specifically that which I've been paying attention to when reading the various write-ups. A lot of them also seem to like the current issue Tung-Sol too.izzy wizzy wrote: ↑Tue Feb 16, 2021 7:21 pmGood result. I'm no guitarist but don't those folk like tone? So not a bad recommendation for starters? Not all are on the "ragged edge" AFAIK.Thermionic Idler wrote: ↑Tue Feb 16, 2021 7:06 pm Ah yes, I've been looking at the uTracer. Also the eTracer which has enough -ve bias to measure the 300Bs but it's ... a bit spendier.
The Raytheon 6V6's went back in tonight, I couldn't take any more. Aaaaaaand as if by magic... the music's back!
I thought it would be something I'd have to listen carefully for. Nope, even Meredith who was in the kitchen area prepping the chicken and not listening particularly closely, could hear the difference in the first few seconds.
So now to find a matched set of Raytheons. Although I'm not sure whether to stick with those or try Sylvanias, which I've always liked for *SN7 valves. The problem is the 6V6 is used primarily as a guitar amp valve, so most of the opinion out there is from guitarists operating them at the ragged edge.
I do wonder why NOS valves sound better in general - surely if these things are operating to specification it shouldn't make any difference? Or is that the problem right there?
