Damn... it's finished. Voltages are on the high side, but wall voltage is extremely high at the moment, so I will have to wait before I zener this one down.
All in all pretty in the same ballpark, so I decided to light it up. Biased at 83%, so is this safe? It says 24.8W/ tube ... on a 36W OT???. Man this sounds huuuuuge!!!!

Fantastic job, it sounds great!

I still need to record a demo of mine...that got procrastinated a little. lol

Are you using 6L6 or EL34? Your voltages are good for EL34 (81%), but would be high for 6L6 (107%).

Thanks,
Josh

6L6 kinda.. well sovtek 5881 WXT, which are 26 watt GT 6L6B tubes... salvaged from an old f€nder. They have to do for now...got some mullard EL34 on order...
Why do you say they're too hot biased? According to the robrob tube bias calculator they're 76.5%

Oh, never mind then. I thought you were using regular 6L6 19W tubes. You're good where you are, anywhere between 75 to 85% dissipation.

Thanks,

Building the combo shell. It's gonna be 1" deeper than my other tremolo TMB amps, due to the deeper chassis.

Please post a youtube demo, so I can include a link when I start selling the PCBs. It's nice when the demo isn't always me. ;)

Thanks,

A movieclip or soundclip?
Man, this sounds even better than the 18W! Bolder and meaner to be exact. Glad I made this one..
Cab is painted. Tolex the thing tomorrow... hope my grill cloth will arrive tomorrow too. Hope you don't mind me using the type you use. Not to copy your amps, but I like it a lot. Will have all black piping and a gold logo.

A movie. Sound clips alone aren't enough. I didn't invent the tolex. ;)

Not the tolex.. the grill cloth is nearly the same. I use regular black tolex.
I will make a video when the amp is finished. Promissed!
