Time to start building this thing. Wish me luck

Update, update. I posed a question to Josh @ JHS asking to clarify the various marketing material indicating that the NOTADUMBLE is suggesting it's a exact replica (his words) of the Dumble A Box Later. I carefully presented the case that some things aren't lining up based on the gut shots Gil prov...

Maybe leaving the forum open to registered members only would help. At least for a while

Yeah, there's 3500 guest currently online. A double of they yesterday. This is mental.

Same here. Forum is also slow, and I got logged off a number of times.

Yup! I have been very slow proving out the v2 design (too slow, I guess!) and it works better than I thought! I'm trying to wait until the tariffs cool off before ordering v2 boards from JLCPCB but grabbing onto this momentum might make the investment worth while... I thought tarifs will affect thi...

Somebody needs to buy the new JHS NOTADUMBLE and trace the "A box later" side of the circuit. Apparently JHS traced Mayer's original unit :D That's the plan here :-) It's kinda funny, if you watch the video ( https://youtu.be/n9wNpgWJhYo?si=8whdWRmtI36zh45J&t=210 ), a few things stand out to me. Th...

FWIW those German TAD caps are nice in fender-based circuits. To me they sound different from most caps out there, but resemble the older american mallory filter caps Perfect values for my Dumble build, too. I already reordered a set. I won't open them of course, but I'm hoping for equally close to...

FWIW

Yeah, its a treasure. I did my own layout for the #124 and since I cannot go "monkey see, monkey do", and I still want a quiet amp, I will be studying this a lot. Thank you R.G., for decades of great resources

I have just bought the chassis from Amplified Nation, so we can assume I'm officially game on

Perfect timing, thank you

Email me info sales@amplifiednation.com

If there is enough interest I could do it but would need some documentation released so I'm not responsible for getting amps to work

I can do a layout for that. I'm happy to pay back to the community

While we there, Switchcraft 12A good for the fx loop and speaker outs? Whey aren't the stereo type, right? I will be using 13E for the FET 13E works fine for the FET, in the TAG eyelet board schematic the connections are consistent with 14B See: https://ampgarage.com/forum/viewtopic.php?p=104228#p1...
