Hi Ken all the power supply cct is in my head , I don't know if I should show you this ,but here goes , The two volt supply is via a LM317 . Grid bias is via a small tx and a nine volt reg and two preset pots ,to set the individual biasing , The HT and LT is from a OTT tx giving 150 volt ,this feeds a series of six 20 volt zener diodes , thus feeding different HT voltages to all stages of the set.
I think you could call it a bread board lash up , but it works , I could build a case around it with vents off course , having loads of fun with this one but I still don't understand why it works so well with no oscillator running , oh just checked the IF's are non adjustable at 140 kc/s Mick.
