Mine's a 1969 50w Bass spec with a couple of tweaks and changes.
It came to me as a semi-working basketcase as part of a trade. For some reason I was intrigued by this amp and somewhat overconfidently thought I could restore her to her former glory. This turned out to be quite a learning experience, considering I had no electronics background and had never been inside an amp before.
Here's what she looked like when I got her. Head box had been recovered in some horrible ordinary vinyl material, the white beading was actually made from split twinflex speaker wire, and some previous owner had marked there favourite settings on the faceplate with a permanent marker, and polished off most of the original faceplate markings:
The circuitry was a mess with many of the original parts gone. Pots were badly rusted, siezed in some cases:
The speaker cab was awful on the outside. The beading routes had been filled with wood filler and the cab recovered in blue vinyl. This vinyl as well has the grillcloth had been spraypainted black at some point. But, when I opened it up, I found 4 beautiful 30w Greenbacks that were all in excellent working order:
I stripped the cab right back to bare wood, filled all the dings, cleaned out beading routes etc:
I drew a vector diagram of the faceplate to scale, and had a full new set of markings laser etched onto the old faceplate. These markings will never rub off:
Recovered headbox and speaker cab:
I rebuilt the entire circuitry with NOS parts where I felt it was important and installed a PPIMV:

Sorry for the long post and ton of pics you've probably seen before, can't help gushing like a proud dad!
