Bias adjustment kit

Post by VelvetGeorge » Thu Aug 25, 2005 1:34 pm

I listed a little kit to add a pot to the JTM 45 kits. Nice and simple.

I'll get a diagram made up.

Well, I added my own ( I didn't see a 100K resistor for biasing, so I had to try something with the 82K) and it works fine, just looks a little tacky. It's one of the pots that's meant to sit upright and I tried to mount it sideways.

He loves to see us do it the hard way, torture is one of his better sides. He calls us BETA testers, I think we may be borderline guinea pigs.
May the good Lord take a liking to you!

See he ain't all bad, he upped us in rank! Thanks George! The bias pot will come in handy. I checked my bias again today and it seems it's settled in at 40-39, with the 82k resistor which is not bad, but I think the sweet spot is the 42 number for me, it seems to put the icing on the cake.
May the good Lord take a liking to you!
