They're normally used in DC power switching and are the controlling componants of the new generation of battery-operated car motors. Can they be biased for linear operation, and thus used in audio? I'm thinking of plate modulation without a big plate transformer. I'm also thinking of B+ level control without a variac. I've done this before at lower voltages with standard bipolars, and I think MOSFETS will work fine as well, but these things can handle up to as much as 3300 volts VCE (woof!) at multiple amps. You can get one that will do 1500 volts at 10 amps for *two bucks*. Would be pretty cool to modulate my 4-1000 AM rig with these in the B+ line, but they gotta work linear to do that. 73 Dave S. ------------------------------ Date: Wed, 31 Dec 2008 15:48:44 -0500 From: Ed White WA3BZT Subject: CHU Move To: Old Tube Radios Message-id: <495BDAAC.7090000@verizon.net> MIME-version: 1.0 Content-type: text/plain; charset=ISO-8859-1; format=flowed Content-transfer-encoding: 7bit Is the CHU move tonight?
