[R-390] drill a hole next to or just under the KC tuning

[Gord Hayward]

Is drilling holes permitted or is this an unforgivable heresy?  I'm 
still debating a couple of 9/64 hole in the rear panel to locate a
220 ohm Dale resistor near the B+ fuse if and when one of the 26Z5 tubes 
dies and I have to go to silicon. I think that will be
better (and easier) than putting it under the AF deck.  I'll repeace the 
selenum bridge at the same time as it will have to move to
make room for the resistor.

BTW would a high power Zener be better than a resistor to keep the B+ 
voltage down with the solid state mod?
