That’s odd. I googled the same exact phrase(ALMOST) and didn’t get a hit on this site. This is the page I was looking for. W7RF has some remaining part’s for the Landwehrs. I bought some 5 pin power connectors off of him several years ago. Thank you W3AB, I guess J

Awhile back I purchased a set of Landwehr Preamps, for 2 and 70cm. I just
got around to setting them up in my station in NJ. Both are DOA, so now I'm
trying to fix them. Does anyone know where I can get a schematic, or anyone
that can fix these that has the parts. Both units relay are function 100%,
issue is with the rx on both units. The 70cm one shows hi SWR and low RX,
the 2m one no preamp, or low RX. I'm sure both will need preamp chips, I'm
not sure these are available anymore on the open market..
