I stumbled across three while cleaning up a transformer box (they had fallen out of the PCB stock).

How many you need?

I have been patiently waiting for a board to come up but no such luck.

However at this moment (February 2020) there are some boards on eBay that are very good but they use the 6N3P / 5670 driver tube. The Chinese ones leave much to be desired but the Russian 6N3P-E are very good.

Enter below sttring for search:

Mains transformer specification once again is not good enough to cope with the spikes in rectifier current, it needs to be at least about 220mA.

A chance can be taken with the Edcor XPWR050 or the Edcor XPWR213, hopefully they will not burn out the HT winding. If they do not run too hot then you -should- be OK. Personally I would take the 050 and then recalculate the cathode resistor: each power tube their own resistor and capacitor and ensure that the anode does not exceed its Pd.

Hope this helps!
