For Sale: AM-6155/GRT-22 VHF/UHF Amplifier

[Brian Carling]

I can tell you guys this is a GREAT amplifier.

I had one on 2m years ago. Built in AC supply, excellent inside.

You do NOT need to do that Svetlana tube conversion It's not worth it. I got 400
watts p.e.p. out of mine with the stock tube on 2m and worked a lot of DX on 2m
SSB with it.

Fair Radio used to sell them. VHF ops realize that the true output level on these is
a lot more than 50 watts.

I would be tempted to buy it if I were more  active on 2m SSB & CW...
