37-60 alignment problem
#1

Hello All,     I'm working on a 37-60 that was a rust bucket.  It cleaned up really nice so I changed all caps and most of the resistors.  Powered it up and got a local station right away which was surprising because I took this thing down to nothing to get all the rust out of it.  Anyway I thought I'd give it an alignment since it was working.  Did the IF part no problem,  got peaks from all the trimmers.  So I moved on to the SW part and seemed to go pretty good.  When I got to Osc. and Ant. part of the Broadcast band the instructions said to turn receiver dial to 1600kc and signal generator to 800kc so it is using the second harmonic to adjust to 1600kc.  When doing this I get no signal at 1600 on the receiver.  Tuning thru the dial I get the signal at 1000kc.  Then I noticed that the local station which is 970kc was coming in at 1170.  So everything is off by 200kc.  I tried adjusting the osc. trimmer to get to 800 but there is not enough adjustment.  I run out after about 100kc of adjustment.
    I may be wording this problem all wrong but if anyone has any suggestions I'd be grateful for any help.

  Thanks 

  Dick
