Into the fray with a 116X
#1

I finally pulled the chassis from my 116X yesterday but first, I brought it up slowly on the variac. At 95 volts she came alive with a loud hum. But, she also was faintly pulling in a couple of stations. Wonderful! I shut it down, yanked the chassis, and started to replace the power filters. Surprise, surprise, someone was in there ahead of me, a very long time ago (Repair is dated 7-15-1940). Unfortunately they didn't do a very good job. The double lytic (8Mfd-500V, 100Mfd-100V) had been replaced with (8Mfd-475V, 8Mfd-475V). The real problem was they had pulled the grounding lug off of the old can and just slipped it up between the new can and the clamp. However, the new can was actually a cardboard replacement, not metal, and it shrank over time allowing the lug to slip out as soon as the wire was touched. Not sure what, if any, contact the lug had with metal.

I replaced all three power filters, reconnected the chassis, and brought it back up on the variac. Good news is she plays; bad news is the speaker's bad. At minimum/low volume it's fine but as soon as you start to bring the volume up it starts to seriously buzz and rattle. Since the horsehair around the top and bottom of the speaker has been eaten away (I guess the little devils couldn't reach the horsehair on the sides) I suspect the cone is damaged by the mice who lived in there for a long time. Hopefully the speaker in my parts radio is good.

The amazing thing is it has all Philco tubes in it and I think they're all original. That was a nice surprise. Also, the shadow meter appears to be in working order.
