Changed the power supply from a single silicon rectifier diode to a bridge (making it a full wave rectifier circuit), and reworked the heater string so the 12AV6 has the minimum AC waveform on it, but has half the B+ voltage on it (elevated DC on heaters helps reduce hum into the tube).
Hi,
sorry for pulling-up the old post.
I just started a restoration got this little radio.
I can't remove the PCB from the chassis. Please advise how to proceed. I guess that a little secret with volume knob.
Thanks
