I'd like some advice on the value of a high-voltage power supply capacitor, which I plan to offer for sale. I have a 53uf, 5kv, oil-filled cap (no PCB's) sold (manufactured?) by NWL Capacitors carryi

Hmmm...this cap was in a BTI amp power supply that had been much modified, including a Peter Dahl transformer, but I have no notion of what voltage was being run on the PA. This cap has a manufacture

Ah, but the sunspot number was 31...that does not translate into 31 sunspots because of the means of calculating the SSN. There's a formula something like adding 10 to the combined number of spots an

One thing that users of external anode power tubes might consider is filament voltage. My experience in commercial FM broadcast rigs is that running a PA tube at it's rated filament voltage from day

Yes, the voltage did have to be increased to maintain power output nearing the end of tube life. Not too many hours left at that point but a good indicator to get another tube ready. Better than a su

D'OH...of course, I should have thought of that with the inductors. However, I am seeing discrepancies on capacitors, as well. For example, a good quality 5kv mica, rescued from a salvaged broadcast
