Re: popping fuses in a marshall
Hi Bernd  
 
I measured grid2 voltage and plate voltage yesterday and both are about 510 volts with reference to ground.  
 
EL34 should stay 800 volts plate voltage, but maximum grid2 voltage is set at 425 volts, so I will change the voltages.  
 
I have gone through the schems yesterday evening and noticed a 240 volts AC tap at the main power transformer; also I have "variac", which I bought at "Conrad" (originally it was ment to control drill machines).  
 
Thanks, Stone
