This page is about the IMPACT 1015 60W amplifier head.
In August 2000, I got one of these amps from a friend who had found it on a
garbage dump. The front plate is missing, else it's in quite good shape for the
age. The chassis is in excellent condition! It has very good looking transformers, and the output transformer has the same size as the
power transformer. It has
a quite advanced way to change the output impedance, a way to keep the whole
secondary winding connected at all times. (See the schematic!)

60 1015PA-S (I have drawn this from my amp, so I can't be sure that this is the original
schematic, but my amp doesn't seem to
have been modified in any way.)
Bright version. Impact 60 1015A
The current revision of my own amp: Impact 60 1015PA-S/2
