I can vouch for the 2k2 resistor swap. Just built a vero board pendulum, and swapped in a 560 ohm resistor in place of the 2k2 and it definitely cranked up the speed! Thanks for this @Dirty_Boogie !!!

Yep. That’s where I found out about the negative feedback resistor.lol

OPE! I may have jumped the gun. I just read about the negative feedback resistor and the 680nf cap how you can put a trimpot in place of the 220k resistor and vary the value of the cap to change the gain. Is that the only way tho?

Apologies if this has been discussed in other threads, but I can find them. I built a Prince Albert (Catalinbread RAH) and it sounds pretty good, but there’s not as much gain as I think there should be. I’m prolly wrong about that, but in the off chance I’m not, is there any way to up the gain...

Thanks for telling me about this. I’ll take a look at it and see if I can figure anything out!

Yep! I swapped a Heavy Water build in for the Katana, a boost for a boost, but no charge pump, and now they work great together! No noise, whine, or nothing! Thanks all for the help!

Damn! I was afraid of that. My best bet would prolly be to put a circuit I. There that doesn’t use a CP. thanks!!

I know, I know! I have a hard time with rats nests on vero builds. I’m working on it!!lol thanks for all the replies. I’m gonna try the 470nf mlcc cap, and get the wiring down. I’ve just not ever had the whine change pitch when I turn the knobs, it’s usually just a single frequency.here are the...

P.S. I didn’t have a 220uf cap @ 35 volts, so I put that huge honker of a cap, a 470uf cap @ 50 volts. Also, I didn’t have a 27uf cap, so I put a 22uf & a 4.7uf. I don’t think that would cause the whine either tho, would it?

Hey y’all! Ok, so, I don’t have the best pics right now, cuz it’s night time and there’s not good lighting, but I got a few. Apologies for the rats nest, I have a hard time getting vero builds to look ‘neat’. They’re both veroboard builds. I have the EP Bias and Katana in a single enclosure...

I like the idea of SMD builds! So long as there are always thru-hole builds available. I just don’t like the idea of fully converting to SMD over an amount of time.

YES YES YES!!! So long as there is a retro active system, where prior purchases may be able to count towards points. Possibly a cut-off date, idk. But, I do like the idea of a points system, for sure!!

Thank you very much!!

Awesome, clean build, dude! Do you still have the layout for this? I can’t seem to find it anywhere!

I would try a new 3pdt switch, and wire it up without the breakout board first, to see if it’s the problem. 3pdt switches can be kinda ‘fragile’ to work on with heat. If the iron is left on a lug too long, or repeated heating, the lugs can shift from the plastic and epoxy melting.
