68 Silverface Bassman rebuild

[TWANG]

New switch and new 100K2W over the switch.
that seemed to stop the popping, but only for a while.

[Structo]

Have you tried a .01 ceramic cap across the STBY switch?

[TWANG]

No I haven't. Never heard of that before.
Seems to affect V6..
when I hit play, V6 gets a small jump in brightness.. a tick of blue glow.
and the pop.
I was just going to go through all the connections to V6.
and I'll give this a shot, too ty!

My bassman 50 pops when i throw the standby switch. Never really noticed it before. Hmm

[TWANG]

I put an .022uF 1Kv w. a 100K 2W over the sby.
now.. only V6 lights up.
swapped tubes.
yep tubes are good but I lost V5 somehow.
freaky.
Also the G6 mods don't work out this amp.
what I looked at said for normal channel
but they show the far right side of the board.. which is the bass
ch. on my amp.
right now I just want my power back.

Check to see if your 1ohm resistor shorted out.

I got it working again.
I never did get all the pop out of going from standby to play
but it's very soft.
Even diodes didn't do it.

The owner picked it up today.
Brought his strat, and a 2X12 loaded with scumbacks.

god it was huge and really nice.
He tested out the gain switches and the tone stack cut out device I rigged up..
based on dumble mods for gain.
He liked it.. I was really impressed more because those scumbacks just totally rocked more than anything I had it hooked up to.

Plus I love his strat.

So thanks for all.. now on to a JCM800 w. no signal passing.

Had a AB165 and made the bass channel 5F6A and used the unused gain stage as cathode follower to tone section.
Made neg feedback switchable and tone section bypassable.
Pretty awesome sounding.
