[Amps] Soft Start

[Jim W7RY]

I recommend 10 Ohms. I use 2 resistors and 2 relays. There are fuses in 
series with the resistors to protect them.

Why would a cap blowing up cause an issue with a step start circuit?

Again, I use 2 resistors and 2 relays on a small circuit board.

Once upon a time, i had a capacitor explode upon start up. I've heard 
stories for and against adding a soft start circuit to my amplifiers.(Some 
say 20 ohm resistors, and others say 30 or 40 ohm.) That and the price of 
replacement tubes. In my case i have two TL 922a amps using 3-500z tubes.
Both set up on 240vac. What do you all have to say here. Thanks
