WTB: Heathkit 455kc IF CAN

[Chuck W4MIL]

GM gentlemen and the list..................

It's been a long time ago, but I "converted" an SB-610 by using a 455kc 
IF can from an old All-American 5 AM radio.  I don't have schematics, 
etc for the 610 but I seem to recall that the Heath can was just the 
inductor and that a specific silver mica cap was chosen for resonance.  
If the AM radio IF can is used, one should pay attention to it's 
construction.  It was not uncommon to find a fixed mica embedded in the 
plastic base.  So if the can is already at 455kc, you wouldn't need the 
cap that Heath originally called for.  A signal generator and a scope 
will put it right on the money.

Hope I haven't confused anything here..........memory is faded, but I 
recall it worked fb.

If you find one, let me know. I am trying to convert my SB-620 to 455 
also.
