I have a Conn 813 electronic church organ, which uses dozens of 12AU7 vacuum tubes, as well as a vacuum tube amplifier, one of whose rectifier tubes accidentally shattered during a move.
My project is to replace the broken tube with solid-state diodes, of which I have several dozen.
The amplifier is a Pritek (Chicago) Power Amp Model 4270, 115W output, peak 180W.
The broken tube is a 6CA4, a full-wave rectifier, whose spec sheet I've attached. Apart from the heater pins, which I won't need, the pins used are 3, the cathode; and pins 1 & 7, plates # 1 and 2.
I'm guessing I'll poke two diode cathodes into pin 3, and their anodes into pins 1 & 7, assuming they'll handle the voltage. If not, I'll just put some diodes in series, do the same thing.
But I've read something that suggests I'll need a resistor somewhere to suppress some voltage transients, which I don't understand.
Can someone provide some guidance on this idea, and explain the voltage transients and suggest a resistor?
