Hi everyone,I have been working blind on this radio and it is now working quite well but I would like to have a look at the schematic to clear some points. I believe it is a Chev radio and from another website I have gleaned this number :986698. I'm not sure if this is the Chev part number or the manufacturer's number.The date seems to be '53 or '54.Rider seems not to go up to this date. Can anyone point me in the right direction to find the schematic for this set?Most of the valves (tubes!) are Delco which made me think this was a Delco set and it may yet prove to be so but there are  absolutely no marks or identification on or in the set anywhere. Thank you.
