The PHILCO Phorum

I'm working on a 37-600, wanted to start with the 4uF and 8uF filter caps. This is my first set with the Bakelite cap blocks and I'm having a problem navigating under the chasiss. There are 3 blocks, all of which house low-value bypass/coupling caps (3615-DG, 4989-DG, and 3793-DG).

The filter caps are identified as part 31-2149 (which I can not find on the electrolytic cap listing at http://www.philcorepairbench.com/lytic.htm ). On the schematic, the filters are identified as part 35, but I can not find any such part number in the call-out of under-chassis parts (schematic at http://www.nostalgiaair.org/PagesByModel...013206.pdf ).

I can not find anything which looks like discrete filter caps, and there are no other blocks.

What am I missing??

Thanks for any guidence/help!!

Try the rectangular can mounted between the IF transformer and the power transformer.

It isn't identified, but since I do not see any drawing of a conventional cylindrical electrolytic, I'd bet that is the part you seek.

I've never owned, or worked on, a 600 or 37-600; only 602s and 37-602s, which do have a conventional multi-section electrolytic.

DOH!

I feel like a real dummy missing that. I focused on the under-chassis area and those Bakelite blocks, and kept looking for the mysterious "Part 35." I haven't pulled the cover off the filter caps yet, but may be back for more info once I do that!

Thanks so much for the quick response!

Don't feel bad. Anyone could have missed that, seeing as how the electrolytics are not identified in the parts layout drawing.

Thanks for the confidence-building comments!

I have the new e-caps wired in, and with a little adjustment to the regeneration control, she's playing quite nicely sitting on my basement workbench. I still have the other caps to attend to, and will check the tubes to see if they're up to snuff. The alignment looks like it will be a major PITA -- calling for a feeler gauge to set the tuning cap initial position!

I'll probably be back for more hand-holding!
