There are screws and plug-in wires on the bottom of the chassis that have to be removed. PTS, Zenith and others rebuilt the IF modules for the duramodule sets. Finding them should be fairly easy - they were often replaced, although not bad, when any video gripe came about. Yes, 90% of the time, the IF module was good, and the B+ cap, a connection, or an IF injection lead from the tuner was at fault.
150- prefix for the IF module, IIRC. I don't have my CRSP handy to tell you the replacement matrix - i.e. which 150- ### IF module replaces what.... Cheers,
