37-630 recap of RF subchassis
#4

Ditto on Ron's suggestion. Sometimes its easier to go the long route, than try to struggle with the extra-extra longnose pliers. Just make detailed drawings, and label each wire as you unsolder it, and its not that bad. Better to to this kind of job right the first time, rather than have to go back in there for that cap that was just too hard to get to. While everythings out you can replace the gum rubber washers, resistors etc also. I bought some gum rubber sheets from McMaster Carr (sp?) and custom make what I need. Heres a shot of the 38-116x chassis before and after..... Kinda scary when you have it all apart, but when its done and playin great, it was worth it. (as you can see I went a little crazy and replaced the leads on the transformer as well. This set also had an open filter choke and open audio interstage transformer) The filter choke in the picture is a Hammond replacement, painted black with the outer paper layer of the original Philco choke glued on - hides it a little..... I have yet to find an original interstage transformer, so I did the R/C coupling, and it sounds great. Hope to find a replacement someday though.....
