I was looking through my tubes and found several 6AC5GT tubes and want to use them with one of the clemintine board i have . it has a higher plate disapation the than a 1626 and is a pin for pin sub , it is a triode with a 6.3 volt heater so i could use it with all the 6SL7 i have around here . The cathode resistor would need to be changed but unsure what the impeadance of the output transformer should be .
