Re: Engineering question about standby switches
I realized something after I wrote my first message. On my ST-70, I had actually set it up like this:  
 
tranny>rectifier>cap>switch>cap  
 
That's why mine failed so miserably, the first cap was dumping into the second one when the switch was closed, and the switch was taking the proverbial whip.  
 
As someone stated in another message, the inductance and resistance of the power tranny will probably help you out as far as surges go.  
 
So upon further consideration, your idea does not sound too bad. I still like Fender's plan, where the switch feeds only into a resistor or inductor and OT CT. Still pops a little though.
