Default Re: DIY battery eliminator for valve radio

I referred to the junky radios as being not too desirable to the collector group, but they were desirable to me at the time.
As of this time I have a few farm radios, they I built an AC power supply for.
I have one of those Silvertone Power Shifters that I reworked for a post-war Zenith farm radio, that seems to work rather well. This one is one that uses selenium rectifiers for both HT and LT supplies. The set uses 1.4 volt valves.
It's really amazing that the original 1000 mfd capacitors are so large. Now you can use higher value, low voltage Electrolytics and not need the choke.
Dave, USradcoll1, always trying to do it as well or better!
