After a repair I documented in other thread, I tested it and "best input voltage" was 200V (wired for 234V) for clean 100W out. I mentioned there too about the advantage of lowering voltage to increase degrees of conduction similar to reduce capacitors, the idea is to lengthen the conduction time and reduce intensity as heath os proportional to I square.
I studied the possibility of adding a resistor in series, before capacitors, but it went to over 100W resistor. This radio as it comes is extremely bad in efficiency, some 540VA in for 100W out.
But besides all above, when I bought the radio near 35 years ago people were talking about the overvoltage and destruction.
I have many PS and no one has a crowbar but anyway, you never know. As this radio was in the expensive side at that time, maybe someone had to find some real or unreal faults.
What works quite well it is the 13.5V PS. When my tantalun capacitors in PA went shortcircuit, the 13.5V PS protection cut voltage. Otherwise extensive damage in the RF unit, in fact the best site to check that fault is in the TX13.5V in RF unit.
Anyway it is a very good receiver. It is the way I use it, and the reason why the 24V fuse is out.
Thanks for the idea on reducing capacity, thanks for the PDF
