Re: High voltage and higher power output - what heat sink are you using?

If you "remote" the 510 by adding even a small amount of wire you run the risk of turning that amplifier into a big ugly oscillator (been there, done that!). One of the reasons the BITX 40 amp is so trouble-free is that the layout is good and the leads are very short.? 73? Bill N2CQR

What I have done with other projects is to mount the output transistor remotely.. ?This allows for easy use of the case itself as a heat sink, as well as makes it easier to use "junk box" heat sinks that do not fit the printed circuit board. ? Surprised I have not seen this option all ready mentioned.. pretty simple matter of removing the 510 and running wire.
