ok, yesterday was the day...finally removed the strain relief, fired up the soldering station, and replaced the 2-prong power cord with the grounded 3-prong on my '69 Kustom 100 2...also replaced the fuse block since the original fuse was soldered in...question there...I picked up some 1.5A fast blo fuses, but the existing fuse was a GJV3, so I inserted that into the new clips...and long story short, it works great...BUT the power switch that used to allow polarity change does not power on in both directions ( with the center position being OFF)...only one - which is really all I need, but any suggestions on why this is?

Also attempted to wire in a new reverb tank, added new RCA patch cables, but it does not work... with the reverb turned all the way down, if the head itself is jostled a bit, the usual spring reverb tank 'crashing' noise can be heard, but turning up the reverb knob does not produce any reverb...any suggestions on THAT one?
I remember you mentioning something about grounding - and the old/existing tank had a ground wire soldered to the outside and it was grounded to one of the cross braces...this new tank does not have this grounding wire...is that it?

Again, thanks for all the help on this one...I now have a beautiful, functioning - sans reverb - '69 Kustom 100 head with a grounded power cable...and the exterior tuck n roll on this thing is just beautiful too in charcoal ...
