Bought on 7/19/18 for a fair price. Once I started going through it I found that someone at
one time replaced the xfmr with a Peter Dahl that has the higher screen output.They also did
a few other mods of which the workmanship leaves much to be desired.
After going through the unit and comparing it in detail against the schematic I determined it
would be best to do a complete tear down and rebuild so I can remove the many mystery
changes and fix the workmanship issues.
Below are some pictures of the amp.
UPDATE: 12/21/18 - pictures of almost finished product further down. Everything now works
up to the point of running some RF through it. That will happen soon......
