You heard about this problem since solid state rectifiers bring up B+ power within a second or so. The 6X5's took longer. Some radios use an 80 or 5Y3 rectifier. These tubes also bring up power before other tubes have a chance to heat.

You will have far less damage from cathode stripping than 6X5's shorting and destroying a power transformer. Haven't seen a problem from this modification.

:I have a Zenith 10s464 with the 6X5 tubes and was told to replace each of them with a diode and 150 ohm 1 watt resistor.
:I thought solid state rectifiers in a tube set was a bad thing due to something called cathode stripping. or am I mistaken?
:Thanks
