Hey everybody,

I'm a new member here, I was directed here from r/gratefuldead regarding a question I had posed there about Ron Wickersham and Owsley's mods to the band's Fender amps in the late '60s. I'm a hobbyist amplifier builder, and I was planning on building a period-correct modded Fender Twin Reverb as my next project. Is there a spec sheet or circuit diagram floating around anywhere that I could view?

Thank you.
