Re: Josh's Tremolo TMB Xtra Reverb
My other job's keeping me too busy, not even close to finishing this build. Actually I ran into a slight snag. I wasn't paying attention to the tube count between the circuit design and chassis design, and I needed to add another tube hole to the new chassis. So I decided to also make this 36W instead of 18W. Cause, ya know, I love them EL34s.
This is where I'm at now:
I think I might save the PCB I already populated for an 18W build and just build another with the 36W specs rather than modifying the board.
Thanks,
Josh

Re: Josh's Tremolo TMB Xtra Reverb
Why? Look closer at the photo, I added a tube for the reverb right next to the reverb transformer.
Yup.. I noticed. No worries then anyway. Still funny though.. that small chassis. Nice in black too

Re: Josh's Tremolo TMB Xtra Reverb
Some more progress happening...
Here's the chassis now, front panel, PT, etc.. wired:
Here's the new PCB: I'm redoing the PCB to accommodate the 36W transformers. I'm missing a resistor and a few caps, so I need to wait a couple days until they arrive before I can finish.
Thanks,
Josh

Re: Josh's Tremolo TMB Xtra Reverb
It's just a power brick I take along with me when I go to practice. I have one laying loose in every amp I play live with
That said... it's been a while since I took the TremTMB to practice. Man.. this amp is THE sh*t !!! I fear it's my number one forever.. I'm in love every time I play it in my band!!!
Planning a SE 5881 10W build in the near future .

Re: Josh's Tremolo TMB Xtra Reverb
Some more progress today:
It's coming along nicely...but I have to say, I don't like these new impedance switches. I wish the old style were still available.
Thanks,
Josh

The impedance switch making people are forcing us to choose sides. 16 ohm rules!!! Mainly because the nice old celestions are 16 ohmsJMPGuitars wrote: βSat 04/16/22 6:55 pmSome more progress today:

Re: Josh's Tremolo TMB Xtra Reverb
Well, that's mainly because the original 18W OTs best coil was the 16ohm. But yeah, I did consider hard-wiring the 16ohm.Bieworm wrote: βSun 04/17/22 9:16 amThe impedance switch making people are forcing us to choose sides. 16 ohm rules!!!

These new switches need the solder lugs to be sanded before you can solder to them. I hate that crap.

Re: Josh's Tremolo TMB Xtra Reverb
The ones I buy at Tube-Town don't. I'm pretty satisfied. The stem is too short to put on a backplate though.

Re: Josh's Tremolo TMB Xtra Reverb
I finished the build, but I need to troubleshoot a little. Here's how it looks:
I scratched the faceplate when I was making the switch hole bigger. I'll consider making a new faceplate if it's awesome, or if I decide I care. If there weren't so many darn nuts on that front panel I'd probably have done it already.
My voltages are odd, the PI is way off on one half. I'm going to test the tubes and highlighter test when I have some time.
Thanks,
Josh
