37-630 (late version)mid chassis cap question
#5

Thanks Ron!! I will get a box of new #55 lamps from AES and keep them in-house also. I will use the #44 in the shadowmeter socket. I still have to rewire both lamp-sockets also. The radio is about ready for initial "slow-up" on the variac in the next few days to see if I get audio. Someone in the past really "hacked" it up good installing replacement under-chassis filter caps, wrong caps in wrong places in the past! The radio has a complete point to point rewiring (following Riders), even into the coil-connects in both IF cans. Those old cloth wires were in very bad condition to "crumbling" cloth wiring. I went ahead and pulled both IF cans, and after running new wires, tried my best to remember the lead-dress as orig under chassis. I will have to add a 10 watt wirewound field of 1140 ohms? ( is that correct?), and connect a pm spkr for test after the chassis is all back together. Still flying-by-the-seat-of-my-pants on this one, but it should at least make audio after being-dead for yrs, then I can go from there. Thanks again for all your help!! Sincerely!, Randal
