Another issue to be cautious about when replacing hollow state rectifiers with solid state. I only recommend going to solid state if the radio (RX or TX) can have the heaters fully on and hot before engaging the power supply. Electrolytic caps are sensitive to 3 things as a rule, polarity, temp and voltage. The latter is the issue here.
If the power supply is energized before the tubes have had time to heat to temp (many seconds), the PS will be looking into a no load scenario and the PS output voltage will go sky high, likely far exceeding the rating of the filter caps. This will result, at best, in a shortened life for the cap if not a failure. Ask me how I know this
.
Some receivers have a PS switch labeled send/receive which could be used as a HV switch. Some TXmitters have a separate heater and HV switch. If you want to go solid state and enjoy the benefits of modern silicon rectifiers, make sure you pay attention to this.
