Every thing works great kinda want to keep it that way.....no surprises.... Thanks for your tips in advance.....P.S.  I have a SP-44 if that set would match up better...believe their pretty close in design if not the same.

If the panadapter is one for 455 KHz, you want to come off the plate of
the second mixer. You should be able to repeak the first IF transformer
to correct for the capacitive loading of the small (few pf) coupling
capacitor to the panadapter.
