Not much of an update, more an RIP. The After 80 has been retired. I did some work on it a while ago and slipped with my meter probe, this caused some magic smoke and on reflection, a better plan would be to start again.
When it was working it was a great practice amp, real bass tone, and plenty of oompf. It w as the inspiration for @Phil Starr’s Basschat 8” design as the precursor to that was an extension cab for the After 80.
I may or may not do a combo version of that at some point but at the moment I am clearing all existing projects. My new year resolution is to finish everything else before I start another project so do not hold your breath.
