I would think it would be quite easy to install a couple of rectifier
diodes inline in the 12-volt power line from the RCA power plug on the
back of the tuner. That would drop the voltage about 10%. The power
connector on the Ten Tec tuners drives only the panel light bulbs--I
ran my 229 tuner for a long time with no power at all, but I'll admit
that linear dial is easier to see with the lights working.
