6 FAQs about [350 volt dc power supply tube transmitter solid state rectifier]
Are vacuum tube rectifiers better than solid-state diodes?
Vacuum tube rectifiers have inherently lower noise contributions to the DC voltage of a power supply than solid-state diodes. The physics that govern a semiconductor-based diode makes for significant switching noise every time the diode blocks the negative voltage swing and turns on and off.
How does a solid-state rectifier work?
As already stated, a solid-state rectifier has essentially an instantaneous turn-on time, so the power supply is up and running right away. However since the tubes are still cold, the current demand is low so the power supply voltage is higher than normal for tens of seconds until all the tubes are warmed up.
How do I orient a solid state rectifier?
When orienting them in the circuit- look at the diagram for a tube diode, then close that gap between filament and plate for correct orientation of the solid state rectifier. You can confirm this by going the work in steps and checking the voltage at the business end of the rectifier after it has been soldered to it's leg of the transformer.
How do I change a tube recifier to a solid state rectifier?
To convert to a solid state rectifier, first ensure that the 5v heater for the tube rectifier has been isolated from the circuit. Then, use diodes with a peak inverse voltage (PIV) rating of at least double your secondary voltage. I recommend using 1n4007 or connecting two in series.
How does a solid state rectified tube amp work?
In a typical solid state rectified tube amp the power supply will be at it's full unloaded voltage at switch on until the tubes warm up. During this time the B+ voltage will be at its max, as will the AC voltage coming from the transformer since it will see no load after the filter caps charge up.
What diodes should I use for a solid state rectifier?
The piv for the diodes should be rated at least double your secondary voltage, I use 1n4007 or connect 2 in series to make sure as they are cheap enough. If you really want to change to solid state rectifier, then i would check that the 5v heater for the tube recifier has been isolated from the circuit.
