I've got an LPM -887 model. Not sure what the difference is.

I would use an 1N60 diode. This crosses to an NTE110.
I just repaired a Drake MN-2000 using a pair of NTE110 diodes. The tuner originally used a pair of 1N34 diodes that crossed to NTE 109. But I already had the 110s so I stuck them in. They work fine.
