Re: TS 790 Sub display



One note about the RS grain of wheat bulbs is that they are really 12v bulbs
and have short lifetimes at 13.6v+......a cheap and dirty solution of a
series resistor dropping the supply voltage to 10v (or less) will keep you
out of the box longer...My Drake UV-3 has 5 bulbs and I put 3 on one series
resistor and 2 on another.

Good as new!
