Guitar Amp restoration
Hi-Fi Amps
Occasionally I get to build amps for myself. This is a 2A3 Direct Heated Triode single ended hi-fi stereo amp, using a pair of Mullard Flat Plate 2A3 valves and Siemens C3G pentodes.
These valves are incredibly rare and worth big dollars on the world market - collectors and hi-fi nuts will die when I say that I bought the 2A3s for $1 each.
You just gotta keep your eyes open and know your stuff.

Fender Showman
The owner of this Fender Showman amp (100 watt) wanted a 2 x 10" cabinet made up for violin, bass, synthesiser, and keyboards. The speaker cabinet is a vented design, tuned for a 7 string baritone response. The speaker cabinet dimensions are the same as the small Fender cabs.
