No disrespect intended at all here! Sounds to me that you jumped in over your head on this one, by going too-fast? Dont fret!, ....Ive done that before myself many yrs ago! All your previous questions/ and answers /,.. then..( to your own questions)/ then questions asked here again, is most confusing at best! Im not trying to be a wize-guy at all! Not my intent at all either! Most sealed-type orig mica caps are usually still good.
Most usually,when restoring vintage radios, (unless previously hacked by someone else),.. the only orig caps that need to be replaced in any vintage radio are the old wax- bypass caps, & electrolytics (observing correct polarity), Going slowly!!!... 1 item at a time! If the orig tubes are still good, w filament continuity, & pin connections are good & clean, you usually have a good starting point to get audio started. Then, a "signal-tracer" comes in very handy in tracing the circuits from front-end-to-amplifier sections of the chain,or amplifier-to-front end chain of the schematic to find your suggested probs you are having in this restoration. As much as Id like to help you here, Im not sure how many mistakes have already been made? If you are a "newbie" attempting your 1st restoration, go back over everything you have already done closely, and make sure you soldered everything (your new parts installed) back into the proper places (point-to-point). Trace over all your work again from the beginning, go slowly, (pc by pc).
If the set your trying to restore had been previously serviced before you owned it, perhaps someone else had parts placed in wrong places? Schematics never lie!! In any case, its best for newbies to replace 1 item at a time, and make sure, you keep-up with what youve already done, so you can carefully go back to the starting point all over again if need be. Your (proper) schematic never lies!! !! Look at your schematic, then start from the power-trans, & go fwd from there, follow the schematic slowly, and make sure your (new) parts you added,
are in the correct positions.A good ol trusty GE tube manual always helps also! You CAN do it!! (reasurrance added here)!! Best of luck restoring your vintage Philco!
