[Heathkit] Signal Tracer

[W5VPU at aol.com]

Hi, everyone.
 
I seek information about Heathkit signal tracers.
 
I am trying locate source of a problem in receiver section of a Swan  
transceiver and think the use of a signal tracer would help me isolate the  stage. 
The Swan was working well, then suddenly stopped receiving. I wonder  if a 
signal tracer would be useful. So I've been reading  about various Heathkit signal 
tracers. I believe I would prefer the late  model tansistorized Heathkit 
signal tracer IT-5283 for its mobility using the  batteries.
 
First, what has been your experience in using this particular signal tracer  
as opposed to some of the earlier models? Am I on the right trail?
 
Second, what would be an equitable price for one?
 
And any experience with a signal tracer you can share. I'm not in a  big 
hurry, as the Swan usually sits on the shelf. But I would like to get it  back 
where I can use it occasionally. Tubes check OK. 

Thanks for  your time.
