I hope you appreciated the somewhat sarcastic humor from the standpoint of a sound man.  Been there done that...

I am, however, curious.  How do you intend to "prove" the obsolescence of Pre/Pwr tubes and OPT's?

Subjective listening tests or the use of a more "measured" approach?

PW
I did appreciate the humor. I especially liked the comment from the sound man "Could you turn it down a little?" Lol.

Proof will be in the pudding; the tone and "feel". But it will just as easily be proved via the scope. I can already duplicate the wave shaping and Ro from just about any class A triode stage using a 12AX7 etc. Most designers have missed the boat when trying to duplicate the breakup of tube circuits. Also, I can operate the MOSFETs in either pentode or triode mode. So I'm at the point I can take any existing tube guitar amp and replicate it using MOSFETs etc.

FETs (all types) already make better tubes than tubes do. Get your mind around that one. ;)

Switching amplifier?  All I can think of in response to that is "yuck".

But then, as I said, guitar "amplifiers" were never really meant to be "amplifiers".

Just giving you a hard time...

Yes, "digital" amp. I know it sounds revolting, but have you heard any hi-fi "digital" amps yet? I have a couple and they are pretty damn good.

Sorry to hear about the amp line PM.

SS Marshalls are not so good. Perhaps yours was better.

Dean Markley still sells amps. I've never heard one live, nor on YT. Must check them out.

btw, they have many or all of the Spectra guitar amp schematics online here.
