Tony McKenzie S.I.R. 36 & 39 article

This Tony McKenzie write-up is basically the best rabbit hole you can go down if you’re trying to understand the S.I.R. 36/39 story and why these amps are such a big deal. Since nobody has a confirmed schematic, this kind of legwork is what we’re building off of—educated guesses, history, and what’s actually plausible in a modded 2203 world.

Pros

+Great background on S.I.R. 36 vs S.I.R. 34 and the Appetite-era context
+Useful foundation when you’re chasing an amp that doesn’t have a verified schematic

Cons

-Still can’t provide absolute certainty on component values because the original amps aren’t publicly documented
