Thanks Stevem
That seem Ok, I got some bigger resistors and have a pile of tubes.
Switch the fuse sounds good too.
If that's the damage, then back to play.
And Yoda it seemed like 1967.

Thanks

Also when that took place the amps fuse should have blown but it did not because it’s a crazy large 4 amp fast blow fuse.

All original Champs and Bronco’s use a 1 amp slow blow fuse which is what I would use.

For a replacement tube a would get a JJ brand from Euro tubes.
They are a little more like a 6l6 and will far better stand up to your Hendrix hours of playing.

OK
I made it worse, between 15 ,16 now both continuity to J10 but not 9.
And nothing between 7 and 18.
That is after I plugged in and light went out in 1/2 a second. I possibly got Black #7 wrong on hookup?


Thanks.

You do not want anything bigger then a 1/2 watt resistor there.

There that wattage because under normal conditions that’s all that’s needed and also do that they burn up when there’s a shorted output tube and no harm comes to the filament winding of the power transformer.

Cutting out a man's tongue does not mean he’s a liar, but it does show that you fear the truth he might speak about you!
