If you are getting good xmtr output, it very well may NOT be the input mixer (SBL-1).? You can test further -- if you have some sort of spectrum analyzer,? check for spurious output (you might also be able to use another receiver).? Many harmonics and other "junk" from the transmitter could indicate that one leg of the mixer is shot.? This would still allow xmtr output but greatly reduce receiver sensitivity.? Do you have a schematic of the rig? If not, you can download one .

Or just replace the mixer (not a minor undertaking) and see what happens . . .
