Re: Waterloo - Valve Overdrive

Wow!!!
Nice proyect!! ;)

:idea: I'd put a 1K resistor (grid stopper) in grid1 of the pentode section, soldered just in the socket, to avoid noises. :secret:

Re: Sola Sound - Tonebender Mark II Professional [schematic]

Put it first in the chain, just after the guitar. The cause of the problem are the buffers cointained in the tuner, wah and the wahmmy.

Re: Vagabond - a 2x12AX7, 2x50C5 blast from Winnipeg's past

I think, the best U can do is replace the 50C5 and isolate correctly the circuit, with an power transformer and a few diodes... It's not that difficult... :arrow: Just look for the correct grounding. And the re-cap: I'd just cahnge the electros :wink:

I suggest to turn the effect on and just put the diode leads over th four ones in parallel and just use the ears. It's not rocket science... :lol:

Re: Silverface Princeton Reverb being a cock.

That 3M3 resistor is the grid stopper resistor. And the noise, I guess it's just an oscilation.
I suggest to take a look at this read: http://www.valvewizard.co.uk/gridstopper.html
And move all the grid stoppers to the tubes sockets ;) .
Best regards!!

Just a tought: it's a perfect candidate for DC70 or any subminiature tube, powered by nixie supply :idea: . It could become into a regular sized pedal ea...

Re: Tube Treble Booster

U can try it with 6AV6, 6C4, etc... Singles hi-mu triodes ;) .
Or a pentode, as EF86, EF144, etc... in triode mode; a thing that I've never seen is a triode in pentode mode, reaaally nice idea :lol: :hug:

Yes, there's a noise on tremolo mode. I gues it's 'cause the whires are too long... well, I had no choice with that: it was made for a friend of mine, and he wanted it in a little box [smilie=rolleyes.gif]
