1927 Eveready (National Carbon) Model 1 TRF Radio
#27

I've finished rewiring the radio's power supply circuit and I powered it up at first without any tubes in it and it drew about 1.2 Amps and with the tubes in it drew about 0.2 amps and the B+ voltage with the tubes in it (not including the tuner section) about 160 VDC which is about right and the High Voltage winding was producing about 400 VAC which is about right, and there wasn't any smoke or sparks or arcing so I think we're off to a good start, just waiting for my resplacement speaker to come in the mail for the speaker for this radio.
