1531.0. "Add ground to tube amps?" by HPSCAD::RFACCENDA () Tue Oct 24 1989 20:12

I have a fender bassman and a fender bandmaster. It bothers me that these
do not have a ground plug while the solid state amps do (at least some of them).
I sometimes use them both with a keyboard to get `stereo' and always feel I'm
going to blow something if the polarity reverse swiches are wrong or if I power
up the units in the wrong order or if I step in a puddle of beer or .....

Can these amps be rewired so that the chassis is connected to ground?

Would the polarity reverse switch need rewiring or removal?

Would rewiring to add a ground pin be useful/beneficial or does it create
other problems?

Have any of you ever done this?

Thanks in advance.

***** Yes,they can be rewired with the chassis connected to ground,the
recommended way is with a ground lug to the power transformer bolt's.
However older Fender's just soldered to the chassis.

******* No it doesn't

Would rewiring to add a ground pin be useful/beneficial or does it create
other problems?

******** Yes it does make a beneficial,some cases minimal to what you
hear,but what you might feel makes a difference :^)  


Have any of you ever done this?

******** Yes at least a dozen times.... The one thing I really hate is
when someone rip's the ground pin out of a three prong plug usually 
because they don't have an adapter for a 2 wire outlet....
