When doing this type of work, I compare both copies, as Philco built the same radios. both pre and post war.

thanks again,,
i will do some searching,,, i also found a rider schematic on this radio,,, however it seems to be a copy of teh philco... i can imagine the tube changes,,,
the other set i need some help with needs two tubes, and they don't seem to have substitutions,,, i started with this one, because teh tubes all work,,,
just a side note, i had teh other set somewhat working,, could pick up quite a few stations but teh audio was poor,, i tested teh tubes and found two bad,,, i put them back in to continue trouble shooting, and the rectifier was shorted, so i have to get some new tubes before i can proceed on that set,,, but,,, i have my hands full here!!!
regards,
john
