Alright, I'm getting ready to make my circuit board order, and I think I'm going to go with SBVT. It's close enough to the original that you know what it is, but not so close I'm expecting a cease and desist from Ampeg. Plus Sushi Box Valve Technology sounds super cool![]()

Have you looked up any local electronics shops? Electronics surplus shops?Typically I would run up to Radio Shack but....
Not yet, I haven't done any work like that in this city. I'm sure they're around though, shipping is pretty fast and maybe more convenient at the moment, we'll see - I should have something put together this weekend at least.Have you looked up any local electronics shops? Electronics surplus shops?
You shouldn't hear a difference in volume between 9V and 12V, the plate voltage will still be the same.Mine is super loud on 9V , didn't notice much noise with DC7 or 1Spot (home studio volume though).
Please send pics of mod![]()
The switch washer is acrylic, laser cut in houseView attachment 4155995 Now we're getting somewhere. I have everything I need, except components? Typically I would run up to Radio Shack but.... guessing online is the really only well known source for components, dang - on a unrelated note, the sushi switch washer, @Sushi Box FX , glass?? Can't wait to try her out. @shaggy45 what supply are you using?
That looks awesome!View attachment 4156250 Oh boy!!!
I actually have a Dr. Wattson on my bench right now, maybe I should try the mod myself first then let everyone know how it goes and give pointers on how to do it.
Thats exactly what I wanted to hear. I LOVE the Super Stack, but the lack of gain (and it being overwhelmingly bass centric) makes it slightly less desirable.View attachment 4156298
Hot toob shot!
So this thing running at 9v into my CabZone LE sounds freaking awesome!!! Nathan, wow, just wow.
The addition of the gain makes it amazing. I’m A/Bing versus my Super Stack and the gain is in my opinion all the difference in the world.
Outstanding!
Said it before, saying it again - the SBVFine, I'll see what I can doOne thing at a time though, the SVT layout is finished. What did we decide we're naming this thing?

DirtyDuke’s advice was to push mids and presence past noon “were the magic happens”.I like the Sunnday Drive so far.
I’ve never had a preamp with a presence control. @Sushi Box FX can you speak about the tone stack? I feel like everything is interactive with the presence knob?
Thanks!
