Hello Forum-
This is an update for the 630 radio. It is now aligned and working on all three bands. I am measuring about -3 volts on the AVC for strong broadcast stations located 100 miles away in the daytime.
But, I have been following the thread above titled Philco Model 610 by Radio Hound. I am experiencing the exact same voltage measurement issues as he is, such as Tube 80 pin 1 reads 389 volts. and most plate voltages are about 50 volts higher than those listed in the table on the schematic.
Like I said the radio works and sounds good but I am at a loss for the cause of the higher voltages. Could it be the 121vac line voltage at my bench? Could it be my Radioshack DVM ? So I will be watching the thread mentioned for more information.
Also, I found this chassis is a real pain to match up to either schematic or parts list. Closest to page 7-97.
