howdy Don
well I'm not so worried ab out the cover as much as I am a front panel.
They are not cheap, and I have scrapped two of them now lol

I may just have to put this project on hold for an indefinite period of
time.
I have lots of other projects right now. I'm just about finished up with
a 3- 1000Z amplifier with nearly 4000 volts on the plates. Should smoke
pretty good!!
