 GUITAR AMP RESTORATION

Neale Amplifiers also carries out restoration or refurbishment projects for your old amp that has seen better days.

Here are some projects I have completed.

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.

Trimax amp conversion
13 watt 6V6 cathode bias power amplifer with 6N8 pentode gain stage, single tone control and 12AT7 floating paraphase splitter.  This one is a junk-shop restoration using as many of the original parts as possible.  Second hand replacement output transformer, original power transformer and choke.

The owner will be blowing harp through this one.
