That plate voltage discrepancy doesn't matter. That's a very small margin.
After you get your B+ voltage to the sweet spot, you might want to adjust the reverb voltage, but if it sounds good, it's obviously optional.
Thanks,

Yes I know about the obligatory sound clipJMPGuitars wrote: βSun 08/08/21 6:10 pmVery nice! Though I'm sure you already know my next question...
Thanks Jack. I'm pretty satisfied too with the resultsTriodeLuvr wrote: βSun 08/08/21 11:45 pmBeautiful work, my friend. If good looks were measured in dollars, it would be a million!

I learned a lot about the behavior of tanks. I always put a long piece of adhesive foam on top of the tank to prevent resonance and 2 long pieces of that foam on the bottom of the combo to suspend the tank from the cab. The bottom is closed with aluminiumfoil covered 2mm plexi sheet, bolted to the tank.JMPGuitars wrote: βMon 08/09/21 7:46 amSounds great!
When you make your reverb tank bag, live a tiny little bit of room height-wise. You probably will want to slide a piece or two of cardboard in there the length/width of the tank (covering the tank opening).
Thanks,
Josh
Is the owner still on about tilt-back legs? Decoupling the bottom of the combo from the floor when it is tilted may affect the low end, so something to consider. I would also be inclined to consider the speaker choice but also trimming the coupling cap down. Do you have a current schematic, as you built the amp?Bieworm wrote: βTue 08/10/21 3:34 pmAfter playing with it I feel the amp is too bass heavy, even on the bright switch setting. The speaker buzzes.. very annoying. I built the amp playing a telecaster, but now I played my jazzmaster and the buzz appeared...
I was thinking to swap the .022uf coupling cap between V1a and the gain pot with a .0047uf. Good idea to start?
Thanks! I used the latest schematic in the Downloads area, just added reverb.colossal wrote: βWed 08/11/21 10:31 pmIs the owner still on about tilt-back legs?

I will build myself one too!!! I want to keep it as is... great little amp!!!JMPGuitars wrote: βThu 08/12/21 3:32 pmSounds great! A really nice variety of tone (and the demo only scratched the surface of the dirt it should be capable of). Perhaps now you understand why I like ZP's Superlite TMB circuit so much.
