Fender Hot Rod DeVille - Cap job, Switching section over heating correction mod, tubes & bias.
Wangs OD-30H
Chinese built amplifier with Fender type 6L6GC power section. Single channel, selectable clean and overdrive voicing.
I’ve heard good things about Wangs amps. I’m iso a Mesa Boogie Royal Atlantic if you come across one.
Laney AOR Pro Tube 100 - cap job & new power tubes / bias.
Very similar to a Marshall JCM800 with independent Treble, Middle, Bass pull pot boosts. Way more bass then is usable at low volume. To gain control of the circuit put a TS9 drive pedal on the front end, crank the preamp to 10, bring the master volume up to suite the room and you have a chainsaw that can cut through a boy band with ease!
Love those heads!
The first step to setting the bias of the vintage Ampeg Super Valve Technology (SVT) amplifiers.

Tube Matching and Grading
This project consisted of testing tubes for a client. The tubes came from Europe and were manufactured during the end of the Cold War. With the tubes being used in a cathode bias (self bias) amplifier, it was important to match the tubes as closely as possible.

Marshall JCM2000 DSL/TSL100 Bias Drift Issue
