A nice little studio amp
A long time favourite amp of mine... the Princeton Reverb.... nice portable combo with cool Jensen speaker and a 9AB long reverb...
No hum, no trem ticking or other weird artefacts.... top quality PCB populated with top quality parts...I am content !

Differences in the Dumble board version 1.0 and the current Dumble board version dated 2025
What is the difference between the circuit board version 1.0 from 2020 and the current version of the current version dated 2025? I purchased a board off of eBay and the seller failed to disclose that the board was version 1.0 dated 2020.

Hi Jla,
this is Andrea, owner of AAElectronics. Your board is basically as the current one. There have been some minor improvements over the years, but nothing major. You can follow the documentation on website
Happy building :)
Best

SLO 100 Transformers - Help Needed!
Hello everyone! I'm building the SLO 100 for a friend, and I am really struggling with finding appropriate transformers. What are you guys using?
I'm in the US. I found an EU seller, but he doesn't ship to the states.
I could purchase the Onetics set from C3, but they're over FIVE HUNDRED DOLLARS. That's (respectfully) insane.
I've emailed Hammond to find an appropriate set, but they don't have anything that matches the specs for the Power Transformer. Any help is greatly appreciated. I'm willing to step this build down to 50 watts or literally anything that makes this cost effective but still fully functional.

You can try inMadOut (write directly to info@inmadout.com). The owner, Mr. Savino Luce, makes boutique transformers specifically for tube amp, used them in several of my builds.
Just share the schematics and he can give you a quote - probably way cheaper than those $500 😅

HRM Dumble build
Hi
I have noticed that all the Dumble boards don’t have HRM tone stacks. I understand as space is limited.
Do you recommend making a daughter board to accommodate the HRM caps and pots?
Thanks for your assistance
Regards
Mark
