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...

Tube Screamer True Bypass Mod

I am now offering the same True Bypass Switch mod to Ibanez TS series pedals such as the TS-9 Tube Screamer that the major pedal guys are doing. True bypass switches both the input and the output, so when switched off your signal is completely disconnected from the circuit. Without it, only the input is switched, leaving the output of the circuit still connected to your signal path, which can load down and drain a small amount of your signal,...

’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. I will wire this to be an exact Fender AB763 circuit. Notice the small, inexpensive components, ribbon cables, push on connectors, and thin wires going to the tube sockets. It is all done to keep costs down. Not only do these modern...

Up And Running!

Here it is folks, my 5E3 Deluxe Tweed amp! Had to tweak a couple of things, but overall very pleased with the result. Everything dialed in to spec really nicely. A couple of changes made thanks to the talent and guidance from a few of the excellent electronics forums. Here’s a shot of my work before two small wiring changes. I love this amp circuit, ¬†it’s just great. Smooth, raw, mellow, aggressive, compressed, sustain for days,...

Number One 5E3 chassis completed.

Today I put the finishing touches on my first 5E3 chassis. Now it’s time to go through initial power up testing. First a dim bulb current check with no tubes. Check. Then with the RCA NOS black plate rectifier tube. Check. Then putting in the pre-amp tubes and looking at the signal with an O – scope at the end of the pre-amp section. Everything looks great so far, and very quiet. Next we put in the JJ 6V6 output tubes. Happily, the...

Speaker Arrives

The speaker I ordered from Weber Vintage Sound Technology ¬†arrived today. It was hand made especially for my order by the good folks in Kokomo, IN. I chose the Weber 12A125A 30 watt with light doping. That means it is a 30 watt, 8 ohm, 12″ speaker with an 11oz AlNiCo magnet. It has a 1.25″ voice coil, curved seam and ribbed cone. Doping is the black goop applied to the edge of the speaker to dampen it. Weber’s description is,...
