SUPER REVERB AB763 SCHEMATIC ISSUE

Post by SMPL »

I finished my AB763 with Mercury transformers and followed the wiring. I double checked everything and I still get a short on the 6.3 at the first 6L6. Upon start up the heater wires start to cook. at v8 pin 7. I am new to building and would like to thank you ahead of time for your time. Any tips on this trouble shoot would be great! Shawn

hey there...... the heaters on a 6L6 are 2 and 7...... treat the heater wireing
as it own little system...... check it over for any wire ing mistakes.....
or any contacts to ground or shorts..... it could also be the tube or socket too
once a plastic or phenolic socket shorts it leaves a little burn mark that will
keep shorting ......get a good look at the socket..
