The TA-600 uses hollow state rectifiers - two of them (5AR4/GZ34 for the amplifier section; 6V4 for the tuner section). No selenium rectifiers that I can see on the schematic. The 500-S and TA-800 were the first to use solid state rectifiers. The use of solid state rectifiers was continued into the 500B, 800B, 500C and 800C (as well as the 400, I believe).

Two of the 12AX7 audio amp tubes obtain their (DC) filament voltage from the 7189 cathode bias. The other two are tied into two of the three AC filament strings.

Thanks for your advice on the mylars. It looks like it would be a nightmare to get to some of those. It will be bad enough replacing the electrolytics.
