What a superb sounding amp!  If you're going to go with a Marshall, these 50 watt heads are the way to do it.  You can get that tone at more reasonable volume levels.  

The amp has been serviced within the last 5 years by Don Butler.  It received a new power cable and only necessary maintenance in the circuit.  A master volume mod was reversed.  There is a hole in the back of the chassis as the result of this former mod.  One potentiometer is replaced - it must have become unserviceable.

All transformers are original.

Tolex on both sides of the amp as been replaced.  See the pics.

This won't last long!
