Orange OR 80 Restoration

A 1972 Orange OR 80 amp that had been beaten hard came to me recently for a full restoration. I wish I had the “before” photos, but I was camera-less at the time. It sounded really bad and looked even worse. It was covered in grime to the point that the torn and tattered orange tolex was nearly black in places. The power switch was snapped off in the on position, and the AC cord was frayed. The controls were all scratchy. It was...

’65 Deluxe Reverb Reissue rewire

This project will be to remove the printed circuit boards from my ’65 Fender Deluxe Reverb Amp (made in 2010) and replace them with real, old style point to point wiring with beefier quality components.

It is all done to keep costs down. Not only do these modern...

It’s pretty cool,...

Let’s get this thing started

Started to populate the hardware. I am actually building two chassis at the same time, one for my combo and one for my pal Jack Murray, who will put it in a head cab for use in his studio. Jack made this web site. Jack’s cool. Here are the twins as of tonight. Mostly finger tight for now. Waiting on the pre-amp sockets, because I ordered the wrong size the first time, and the fuse holders, because I forgot to remember to order them. Mine...
