| 6v6's in a Plexi?
What would be the potential for me to put some JJ 6V6's in my 1987 Plexi 50 watt RI?? I know I'd have to re-bias of course but would they hold up?? |

I think you might be able to get away with it if you use JJ-6V6s and bias the tubes at no more then 8-10 watts each. It depends on what your actual plate voltage is but keep them running with a little less DC ilde current then what you might with lower plate voltages. Does your amp have a fuse in the center tap of the high voltage secondary? If so, it's easy to put a string of 9v to 12v 5 watt zener diodes in there (back biased) so as to lower the over all B+ rail voltages a little. You probably should run your speaker cabinet impedance on one step lower so as to double the Zed of OT primary... 8 ohms on a 4 ohm tap, 16 ohms on an 8 ohm tap, etc. |

What do you think this would sound like?
