Supro Thunderbolt at Saluda Show

Post by Ken Fox »

I also have Supro Thunderbolt in a non-original cabinet to sell for a friend. $500.00 at the show, if any one is interested. I am not interested in shipping either amp!

I am staring at an original right here in my practice room. one that i got for free! I gotta tell you, they are fantastic amps. Of course you already know that.

I use mine for small gigs and it is great with my ricks and a telecaster. It is one of the good ones with the fender tweed style cabinet. The closest thing I have to it is a cloned tweed fender 5E5 pro. Sounds similar.

$500 might be a little steep for the amp in that shape, but the chassis and speaker would be cool to have. could whip up a correct cabinet in a couple days....

hmmm

I have a working Thunderbolt that someone had chopped out and made into an amp head. I suppose I should try to find an empty amp to put it back into...

Considering some are going at close to $2000.00 on Ebay I wish I had an original cab for this one.

I could not buy a kit and build and amp that sounds this good for $500.00!!

You are right I built a SUPRO clone the two transformers from MERCURY TRANSFORMERS

http://mercurymagnetics.com/pages/mainframe.htm

Cost me $300.00 15" Jenson speaker was $130.00
the tubes were about $154.00 the cap resistors and stuff was about $45.00 the chassis $34.00 I got the TOLEX, piping, Burch plywood $156.00

BUILDING AMPS MUST BE LIKE BEING ON DRUGS
YOU CAN'T GET ENOUGH OF IT

You are always changing things to suite your ear
A real Amp builder never Keeps it all together for to long before he is tinkering again

It beats playing the poneys
I am trying to play a Harlin Brothers 1956 Multi Kord 6 String 4 Pedal Steel Guitar

I have a stock Thunderbolt. It was my first amp and all original. I use it once in a while at BBQ jams etc. Not much of a bass amp, but sure works for Teles!

Did yours have the three pieces of plywood in it

Looks like a new transformer the wires look new
and the orange drop caps
The heater wires should have been Green cloth for that year

Note I have the latest model I have the BRIDGE RECTIFIER not the tube I have 4 1N4007 diodes
