Well, it's been really fun trying to remember my old rigs and then find pictures of the vintage gear. Thanks for taking an interest!
In the very early 80s I was using the Yamaha PG-1:

(it's the best pic I could find on the web, sorry)
From there, I plugged into the DeltaLab Effectron II:

And the power amp was an Accuphase P-300:

The Accuphase drove a pair of 2x12 cabinets that housed a couple of JBLs each. Because I was so poor, I was always inheriting Creek's old PA gear. When we did have the wall of sound, we had made many of our own cabs and these were made to handle the lower midrange.
Max Creek was at the time coming from a mindset of always attempting to get the ultra clean full dynamic range from all our gear, so at first I used no effects pedals whatsoever, and the only "effect" I used was the channel switching on the Yamaha preamp. The preamp also had a built in parametric EQ which I would usually let John Archer set based on what he was hearing out front.
Eventually I added some pedals, the Ibanez auto wah, the Boss Octaver (which I still use btw) and also a Boss Flanger which in those days I had on all the time.
The Accuphase was an amazing amp. It was 300 watts per channel and I would drive it REALLY hard and when I had pushed it beyond what it wanted, it would shut off for 5 seconds as kind of a warning, then turn right back on. I would turn down slightly and everything would be fine.
One night at the Rusty Nail in Sunderland I was playing and the drums stopped in the middle of a song. I looked back and Bob was trying to put my speakers out with his flannel shirt. Apparently my speaker wires were touching (the ones that go to the coil) and they'd gotten so hot that they'd ignited the cone. Accuphase didn't care. It didn't shut off or shut down or go into protect mode; it kept pumping out guitar.
More later...
