[Swan] Need 250C help

[n4tua at aol.com]

Greg,
Very good, Thanks for the look. I am restoring the 250C and I am having 
a hard time getting it to receive well. I am assuming that most of the 
time right now there is little or no signals at any given time to 
receive off the air and am putting a 50mhz signal into the antenna jack 
at about 2uv and can almost not detect it at all. I have aligned the IF 
and get a good strong signal when putting 10.9mhz modulated in at the 
V8 mixer grid. I connected the frequency counter at the V8 mixer grid 
and get 13.117mhz when the VFO is tuned to 50mhz. Here are some 
questions:
1) Is V1 Vfo Amp a tripler? If so wonder why mine is not tripling?
2) Should I not be seeing 39.1mhz at V8 pin 1 (grid)?
3) Do you know why my schematic is different than the actual circuit 
around C105A in the plate circuit of V1 and also different at the plate 
circuit of V8?

I think if I can get the right frequency into the mixer from the VFO it 
may help. Anything you could help with would be appreciated.
Thanks, Collin
