yes I know, that was the first thing I realized. But then it actually shows the pins themselves in correct arrangement when looking down inside the chassis.
There are discrepancies - in one tube the heater is crisscrossed, and in the 25Z5 the rectifiers are crisscrossed (the two halves): no biggie but makes the tracing a bit tougher than it needs to be, as if it is not tough enough already with this cobweb inside plus the Kirk's recapping job
.
>>>>>>>Strap a couple of 1N5408's across that 25Z5.
You mean - replace it altogether? Possible, would have to decrease the cap to catch extra 25V of the filament voltage. Or disconnect the Cathode and Anode and keep the tube in place......messy....
Or did you mean "across the load" to clamp the negative voltage?

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
