Thanks Ron!! That must be the proper schematic diagram since no other place to mount the orig shadowmeter except the escutcheon area!! What looks different on my JF Riders print, is the "absence" of the orig Philco bakelite condenser on the AC linecord (as compared to Philco model 37-2620 JF Riders schematic. This chassis has that Philco bakelite condenser mounted towards rear of chassis,just as Philco model 37-2620 has, & the JF Riders doesnt show it on the model 37-630X you suggested. Also, I am comparing this set to JF Riders model 37-630 in orig volume#7. No mention of model 37-630 "X" model in the orig JF Riders index pages. Perhaps, it is just a different cabinet-style? Would you suggest I just follow the JF Riders Philco model 37-630 schematic, and just add restoration to the Philco AC line cord bakelite cap also? I have the "Philco Condensers & More" book here in the shop. That bakelight cap looks orig to the set also!!! I looked closely at the Riders model 37-630 schemat before I posted here. That 1 bakelite cap is throwing me off, and it is original inside the chassis!! I also need orig spkr field coil resistance data,( should be on Riders schemat?),probably not! Also,which orig cab with proper escutcheon data to search for, to properly restore this Philco back to orig if I can find all the parts? In the past, I have had to purchase separately old "factory service manuals" that cover all the data I am seeking. That may be the case with this receiver, although I will get it working eventually by "subbing" a temporary spkr trans & field coil temp 10 watt wirewound resistor to get a good match just to get the set operational again.The spkr in this radio has 4-wires instead of 3 on many Philco sets. I will research them further to incorporate a spkr field coil and test the set with a PM spkr. Thanks again Ron for sending me in the proper direction!! Anymore data you could provide, or further help in restoring this Philco family-heirloom, would be much appreciated!! The Philco Phorum ROCKS!!! Sincerely, Randal
