Quote from: Scruffie on June 04, 2026, 06:07:37 PMYeah, the forum does appear to be having some issues, there's a note on the homepage up at the top right.
Yeah, it's been doing that a while now. Occasionally I get someone else's account on the main page...

Quote from: Scruffie on June 04, 2026, 06:07:37 PMThink the mystery is solved, still, might be interesting to trace and see if there was any other alterations to the circuit... I do notice an extra diode in the astable section area.
This is seriously cool. LMK if you need a donor. Not that there are any 3004s to build anew  :P

Quote from: Scruffie on June 02, 2026, 02:35:26 PMIf someone posts some decent gut shots it shouldn't be too hard to trace and confirm seeing as we already have the 117 schematic.
I'll PM you. Let me know if you need different angles than what I captured.

This gives another hair brained idea of what could be done to mimic the more lush sounding mod effects out there: parallel/series, multiplexed designs using more commonly available BBDs?

I mean, someone's thought of it, I'm sure. Nihili novi sub sule

Motorola multiplexers as clock(s?)

two MN3004s, two multiplexers ...mod isn't in my wheelhouse (yet), but I'm sure one day non-scientists like myself will make sense of what's happening here.

There are only TL072s on the top, as far as I could see (U10 and U5 were both 072s. Surprised not to find and 022):

Quote from: lars on May 03, 2026, 02:52:16 AMNow if we could just get a schematic...
I'd have to work up to it myself, having never traced anything more than a FF  :P I wonder how much it would cost for Robert over at PPCB to trace it... man works miracles. Or Brian. I'd gladly loan mine to either of them. Looks like only a 2-layer to my eyes. Weird grid-style ground plane, like VFE does.

Nice! So it's the Greatest of All Tone then?

It's getting nice enough I should get out the laser again (no way in h*ck I'm doing that crap even in my garage...)

I'm sure someone like scruffie would know, but I wonder if there's something going on in the rest of the chip contributing to the better SNR over the 3204, and other products in the line. It definitely sounds smoother than my buddy's BF.

The 3204 and 3004 appear to have a small difference in snr (75db vs 87db). Strange that for the same stage count the 3004 is a 14 pin with six not connected, mimicking the 3204's pin out (if you chopped those six off). More complex inner workings?

edit: no, different voltage reqs, for one thing. Nope. Sad.

Just got out in the mail today. Choooooooo this thing cooks! 

Came off of the box a bit crusty, but cleans up. Gonna have to hit it with some CRC and get the right pot lube, because it's unpleasant to touch...

Nice! Is that no-film?

I've actually never built a breaker before. Got a demo of this one?
