Hello
Looking for a complete schematic for a Philco 41-608.

[David]

Something like this?

For future reference...our library has service info for many sets up through 1953.

Hi,

You didn't mention which code it is.

Code 121: https://philcoradio.com/library/download...20Book.pdf

Code 122: https://philcoradio.com/library/download...20Book.pdf

GL w/your project!

Check out Riders Vol 12 page 75-76 and Beitman 1941 page 110.

Thank you all very much and yes I forgot the code it’s a 121.

It would also be helpful to have a list of the caps and electrolytics as a reference. I don't want to miss anything. I am also hoping to get the BOL working if anyone has info on that.

Thank you all.

In the PDF for a 121 that Terry provided above there's a parts list. In that list are electrolytic caps, mica caps and tubular caps. All caps that are not mica or electrolytic are tubular paper wax type. You can replace all electrolytic and paper caps. If you are getting together a list for purchasing caps you can order 630 volt film caps for all paper replacement caps.

Thank you very much. I see the parts list.

The BOL turntable has two idler wheels that seem out of round. Is there a way to fix this or get replacements ? It makes lots of noise when running cause I have to replace the rubber bushings on the motor. Any advise is much appreciated.

[philco4me]

Also I need the short dial string that goes on the knob and around the wheel any idea where to get one.

[klondike98]

Depending on the size of the cord you need this might do. I have bought cord from this fellow before.

Hello
I have started to look at my recap job and I am not sure on a few things I am seeing a .003 and .005 that I did not see in the schematic. See attached pics it seems a recap was done but Iam seeing a 10-10-40 instead of the 8-12–16 electrolytic. The radio plays fine but the old wax caps need to go.
Thank you

The schematic shows a .004mfd cap (part 65) connected to a 220k resistor. Your photo shows the .003mfd cap connected to a 220K resistor. You will have to verify that the two parts physically the same by comparing the schematic to the wiring. When you replace parts that are 60 to 80 years old there is a world of unknown possibilities that can happen over that period. Including incorrect part identification like part 56 in your schematic. It looks like a 0.002mfd cap but the parts list says it's a 0.004mfd. Minor differences like this are common and what you use to replace the part is immaterial since 80 years ago the tolerance ratings for these parts was 20%. Same for the 8-12-16 electrolytics. The only one to be concerned about is the 12. It's attached to the rectifier cathode so there is a maximum value for that cap. Quite often I let my wallet tell me what value to buy, if I need a 0.004 and three 0.005 caps I'll buy ten 0.0047s because I can pay less for the ten than the four. Hope this is clear the numbers get in the way.

Thank you so much. That does clear things up. As far as the electrolytics the 10-10-40 should be ok ?
