Hi,

I am slowly doing a restoration on my 37-670 console and find that there's a discrepancy between what my radio has and what the schematic says. From what I understand, this is something Philco did a lot.

My schematic gives part #71, a .015 mfd dual bakelite block, a part number of 3903-LU. According to the Philco Service Bulletin No 289 the capacitors in that 3903-LU block are .01 and .006.

However, my actual radio has for part #71, a 3793-DU bakelite block that appears to have been installed by the factory. The No 289 service bulletin for that block calls for two .015 mfd capacitors.

I could be mistaken, but I think the capacitors in this bakelite block are somehow related to the tone control.

I've got my schematic and service information from Chuck Schwark and there's no mention of any change.

I guess my question is, should I go with what the schematic says and install some .01 and .006 capacitors or install what the part number on my actual bakelite block calls for, two .015 capacitors?

Thanks a lot for your help.

Tom
