62 6g9 tremolux porn. Plus need some help from the amp gurus

Just took the chassis out of this to see if I could trouble shoot the dreaded thumpy / ticking tremolo gremlin

I gather there is a mod that runs a cap across the 10meg resistor in the tremolo circuit of the ab763 amps. Not sure how to approach it in the 6g9

Any hot tips?

Also the trem is weak. Havent dont the tube shuffle yet. The 6g9 has a power tube bias tremolo so no funky roach to mess with. Again advice. Tubeswell...>

Start with making sure the power tubes are biased correctly. Princeton Reverbs use a "bias wiggle" tremolo design (like this) & if biased too hot the tremolo is weak(er). Nice old amp btw!

Try doing it in your sleep. That way it will be an unconscious bias.

I played one just like that years ago in a Wellington Rockshop, I wonder if it's the same amp.

you like that big boy ? The 330 is an 89. Phenomenal guitar. The 12 string 360 is more modern. Maybe I should do a post today and put up some nice pics and maybe a little clip. Then you'll have a pants party.
