Just a quick Hi, just started getting into CBG and as an electrician feel I need to get in to the amp side of the equation, I hail from Bristol UK and I am looking forward to completing my first build of a CBG and amp set. It may take longer than I want but that is down to the day job. Regards to all, Jon
WallyS: I accepted your friend request and sent you a message. :-)
The op amp that works best is the MC33202PG. Other op amps are far more harsh and unmusical. The MC33202PG is no longer made in a DIP form factor, however.
Hi John, good to know about the pcb. Which op amp works best? Do you mean the IC chip ?
I do have a few stella amp PCBs left. The issue isn't the PCB, it's finding an op-amp that sounds good in that circuit. The circuit is incredibly sensitive to op amp choice. I've tried about 20 and haven't liked any of them.
Yep, lots of schematics online for 9v DIY amps. Ruby, Noisy Cricket, Little Gem, etc. Even seen a guy making tube amps with wall wart transformers and old mini tubes.
Interesting to learn about the Stella Amp -- I've been working on small guitar amp designs the past year or so (doing a ton of Googling on DIY and 9v amps) and never saw this guys work. Just yesterday I reloaded Eagle CAD and plan to FAB out a couple of Preamps and also my multistage 9v amp with a full tone stack. I do totally get this guys problem with parts going to surface mount etc. Zero promises but maybe by Summer I'll offer up some pro to-boards.
That's a tough request, since the manufacturers of the pcb stopped making them. The source point was through www.crazybutable.com, but this source reports no progress in getting more.
There are other DIY options for 9v amplifiers.
