Did you get your amps physical concept from the venerable Lucent LAC? :)

What's that?


Magura :)

When I saw your amp coming together a while back, I said to myself - Hey, that looks like a LAC. A Lucent LAC is a 240 watt / RF / 850Mhz cell base station amplifier for the obsolete Series II TDMA and AMPS. It is a Very ingenious design.

Yeah Nelson - nice fan. So nice it will make you deaf if you hang around too long and it has been known to swallow a womans head of hair (this really happened :eek:)
 
what is it?

For starters, it's a couple of mosfet's from the BAF07, you know, the blessed mosfet's :cloud9:

Together with a couple of Lovoltech's they form the engine for the Donut that you've stumbled on before I guess.

The black block they're all mounted on, is a directional heat spreader, made of carbon.
Keeps the whole shebang at the same temp., within less than my IR thermometer can measure the difference of (0.1C).
