PRC-77/RT-841 RF amplifier? - Steel Soldiers::Military Vehicles Supersite

I'm currently putting together a setup for my M35A2C, however one component has been eluding me...

I have a VIC-1 Intercom system, the AM-2060 mounting base/power supply, MT-1029 vehicle frame/interface and of course the PRC-77 radio set, but I'm having trouble locating a suitable RF amplifier. Either set, the AM-4306, AM-4477 or the AM-4700 would be fine, but the 4700 is preferable.

There seemed to be a few floating around about a year ago but I'm having trouble finding any currently. Does anyone have any possible leads on these units?

Thanks, will do.

Update: Still looking for any of those three RF amplifiers (range boosters). AM-4306, AM-4477 or AM-4700. Any help would be much appreciated.

Another possibility is to locate an old "CB Linear" and if it has transistors rated for VHF, as many of the cheapies do, rework it for the VRC-12's range. Then hide it in a green box! I did this to an old beater and got 10 watts out of it.

I did not pursue further, but due to the poor gain of some transistors and isues with the RF transformers at VHF, (6 meter ham to be exact) it might take a couple stages to get the full 50-100 watts.

But I can tell you do not want to rig it and want the right items.

Look on E-Bay for a seller goes by "Old Buzzard Rich,W2OBR in Beachwood N.J" he did have some of the
Israeli units made by Tadiran that were the same as the unit you are looking for I think. If you don't
find him PM me back and I will dig up a e-mail address.

Hope this helps! popacom / Billl in Ky.

Ebay apparently has never heard of him or their user search function is total crap. If you could find his email that would be very helpful.
