[R-390] R-390A toal current drain ?

[Henry Meils]

Hi again

The PS filter cap is NOT defective.

1st: I unplugged dual filter cap XC606 connected to choke L601and reconnected by alligator leads : the choke still warms up (the cap does not).

2nd: I replaced XC606 with 2 separate caps. L601 choke still heats up -- in fact after about 10 minutes the entire audio modul subachasis warms up.

3rd: I removed both 6AK6 AF output tubes . The choke warms up to a much more moderate degree. The two 6AK6s run quite warm/hot when in operation. And since there is more AF output available then I will ever need, I intend to reduce SG voltage by increasing value of the SG series resistors or just solid-state the audio stage(s).

Of course the professional thing to do is to stick a mA meter in series with the main B+ and measure current changes when removing/unplugging tubes and/or modules.

Can any one tell me the specified rated total PS current be (Max RF, BFO on, moderate LF out) ?

I suppose I could check Google for this info.

Thanks in advance for any good tips.
