I think that all Brownings are collector items now but not one with all of those modifications. I'll not say any more for fear of offending the tech who built it. From what I can see his work looks nice though.

According to the listing, the tech built it in the 1970s, so I would assume that the chances of offending him are probably slim, assuming that he is still alive. Based on all of the threads I've read in this portion of the Grumpy's site, it seems that nearly every "High Performance" power modification (and plenty of VFO-based frequency modifications) to a Browning transmitter has a negative consequence on some half-watt resistor somewhere, or overstresses some other component that ultimately results in a component failure.
While I agree that its historical value is nixed by the heavy mods, it'd be great to have a knowledgeable tech hazard a guess on what other commercial TX design this is based on, or similar to (such as Collins, Drake, Siltronix, or generic homebrewed 50s/60s-era ham TX design, with its 6V6s), based on the transformer, preamp tube and final tube complement used here, and what you think might've gone wrong to drop the output so precipitously from its 2008 performance. I agree that the tech's work looks very neat and am curious to know more about the rationale behind the reconfigured design if anyone cares to weigh in, thanks.

If you like to collect Eagles that have been modified. That would be a nice one. Of course it may need some work to get it back on the air. To bad they didn't leave it alone and use a 180 amp to do the same thing for around the same $ And yes, it looks like nice work that was done to that old bird. 73  |
