[Amps] MRI poweramplifier and powersupply from ETO

[Jurgen van de Glind]

Hi All,

I got the owner of a MRI power amplifier from ETO modelnr: 53-s51d-42
It is complete with PS and the tube (3cx5000a7). Anyone on the reflector
knows a source to get some detailed info or manual of this monster?
The driver is made with 2x mrf148 and 2x mrf150 powerfets.
I like to rebuild it for amateur use, so it would be handy to have some
manuals or detail info. For example what is the voltage of the PS.
Anyway a nice winter project. :)
