I have some of the old Motorola (Micor?) RF decks. I have both the VHF & UHF types. The 2 meter is running a pair of the 8560A tubes. I can't recall the single tube in the UHF decks.

 The question being is there any market for these things now-a-days? I had intended to build up a PS for them eventually. But, got hooked on playing with SSHPAs.

Hi Paul and the group,

I have several of the single tube (high 2m band), dual tube (high 2m band), dual tube (6m band) RF decks.  I created a PS to power the RF decks and converted a couple of the single tube and dual tube units to 2 meters.  The dual tube units put out about 750 Watts with about 5 watts drive.  The single tube units will get you about 400 Watts with 3 Watts drive.  I had a UHF unit (single tube), but used it for spare parts to fix others.

I liked the fact that I could run 700+ watts on 2m SSB with no fan noise.  Just built it into a rack with the heat sinks sticking out the back...

Tubes are by far the hardest to get a hold of now, for me at least.  Maybe I'm too cheap......
