Super easy build. Board-mounted pots w/ gain control, made to fit very comfortably in a 1590BB.![]()
Here are the ExpressPCB pcb/sch files and PDF toner transfer: http://www.justonemorebuild.com/project ... morebuild/
Please let me know if you build one!

I restored it back to 18V:

It seems like these early units came with PP4 batteries. The later ones with the PP3 clip had an additional terminal on the board where the battery clips connected with each other.
Only difference to my schematic is that it has a combination of 6.4µF, 4.7µF, 22µF and 25µF electrolytics instead of the usual 4.7µF and 22µF or 6.4 and 25µF, but no big deal.
Transistors are BC184L.
