Does anyone have a schematic for the 250 kHz IF amp from the AN/ARC-38A?  Just the pin-out info would be helpful.  I have a .pdf version of the 618S-1 Tech Manual, but the IF module in the ARC-38A [mine is modified for USB] is different.  It has 1 less dual-diode tube [5726] and an added dual-triode [5814A], which I presume is the first AF amp which is in another module in the 618S-1.

Thanks.

Since 1958. There still is nothing like tubes to keep your coffee warm in the shack.
