Can you believe It works?! Video or it didn't happen lol: Refinishing the room, so a bit temporary, untreated. Fantastic on Lyr+/HD650's Turns out that 220pf => 110pf capacitor change was required for the logic flip-flops, tried it back stock and static at 88.2Khz+

PCM63 R2R Adcom GDA-600 24/96 Side Quest #1 Master Clock New fast 74xx logic chips installed: Think it has a running shot to work, don't even have the DF1704 filter chip yet! Still works perfectly as stock with these new parts and changed capacitor value. Thanks! appreciate thoughts...

Cool! Yeah, since the master clock is now 22/24MHz (double at 256fs 88.2/96Khz) two old TTL 74xx logic OR gates and D flip-flop latches are too slow... one of the things I checked w/oscilloscope. Was thinking those 1980's logic chips would be maxed out. Edit: Hope I don't have to change the...

Goosebumps!

Live Fantastic render... very accurate on all the mechanisms on stage 0 (ground support tower / orbital launch mount). Hard to believe this is happening very soon!

Surprised there isn't some kind of toggle relay... ie it just takes a pulse to switch it, then resting the coil is off.

Hype aside, don't think I've ever been able to try things (surprising full working functions), tear down, and add to so effectively / quickly!

Hell, at least it's not 14nm++++++++ liquid cooled 600watts idle that also happens to run Starcraft! Soon as +++ time to re-think the architecture ;D >> and C++ is a thing, pointers be damned, so that's cool. Yes, embellished; still love Intel.

Not surd what you're gonna play them on. ;D

@Jason Stoddard Reminder: please update pics/specs on the toroidal transformer Rag2! :P

[Random PCM63 R2R fyi (Adcom GDA-600)] This is a surprising delight to listen to - does need modern ti opa1656's / deleted fcc parts on the output. Classic Adcom cranked class A (the opamps run toasty). It's LiM taken too far! Plopped this here to share the fun playing around with the roots of...
