Title: ARC-38A IF Amp Post by: K9PNP on March 13, 2011, 11:15:21 PM 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.
