Hello Everyone,
Just finishing up on that Philco 49-1405 am/phono combo the problem I'm having first off all I removed couple resistors someone had in series
on the rect tube 50 ohms total .
I can't remember the life of me what was doing there it does not show up in the Riders Schematic Also a 330 ohm resistor connected between R100 160 ohm it connected C102B juntion and R202 a 220k ohm What would be the reason for these to resistors Does anyone have this same set or How about the original Philco Schematic .
The last question is I removed a .1 ufd cap I can't figure why it's there either it was placed between the juntion of the on/off control that also leaded to the phono motor .
And the R202 junction again .
Sincerely Rich
P.S. the only either thing is to build antenna for it since it original one had been torn out .
the either reason need to know if some has this same set or can find some one with a 1950 Am tube philco do they have the same antenna circuit design.
