Philco 37-630 question
#11

Hi Hamilton,

I have corrected my original post. In addition, the following may be helpful.

In the Link to the schematic for this set from the Philco Library, there is a page showing the speaker connections. The wire color is different from your present colors, and the originals are likely faded to non-recognition anyway.

The wire labeled green connects to the 6F6 plate. The wire labeled white goes to the 8uF Cap, 6F6 screen grid and other B+ points. The wire labeled green / white goes to the 12uF cap and the 5Y4 cathode (filament).

Based on you description in your post that the red wire goes to the 8uF cap, 6F6 screen and other B+ points and that your yellow wire goes to the 12uF cap and 5Y4 cathode, you need to reverse your red and yellow wires. Your black wire is in the correct connection.

Hope that my correction to the original post, next post and this post clarifies the situation.

Good luck. This should be a nice radio when you finish restoring it! Amazingly, in the 17 years between the introduction of broadcast radio and 1035, the circuits that this radio uses became sufficiently mature, that it is the basis of most radios and other than style of tube (Standard, Octal, Loktal, Miniature, etc.), and the elimination of the power transformer and field coil, the circuit is substantially the same until the end of production of vacuum tube radios in the late 60s.
