Tor, the bias Voltage can be measured there, but that's not the critical measurement. That's the CURRENT, measured IN SERIES with the power (supply) to the amp. That taken by the biasing and its regulator is miniscule. With most multimeters, a 0-1A scale will do the setup, but with SSB operation that can peak to 2 or 3A. Construction: VERY FB! 73!
ReplyDeleteHat very FB too. Bill, that looks like a slightly different design to present stock, possibly better with room below logo for callsign?
ReplyDeleteThe day I learned where the bias point was on a transistor was a big day for me. Everything changed...keep at it
