I think they used either screen or cathode modulation for AM and a single 6146. So 90W woud be within reach for SSB and CW. Maybe 45W on AM. I think reported stability is a bit on the optimistic side for that era and class of rig. "I think" this was before sweep tubes I emphasize that most of this is a hazy recall mixed with hazy recollections of how most manufacturers did things. IIRC only the "Expensive (Collins) and big, heavy (Hallicrafters) rigs used filters, while most aimed at the rest of us used phasing. I think Collins had a transverter using a pair of 4CX250s and Hallicrafters came out with one matching the HT37 later I'd look at how the circuit layout compares to the HT37 and the external phasing SSB generators. Someone, somewhere must have a schematic. Check with the Boat Anchor groups But other than guesses...Wish I could help. 73 Roger (K8RI) > Some pages list power out at 90w....(could be a typo or misprint)...this is a picture..notice the carrier balance knob...maybe using phasing?? > > http://www.radiopics.com/Gonset/Photos/Gonset_GSB-6.jpg > > -----Original Message----- >> From: "qrv at kd4e.com" >> Sent: Oct 24, 2014 6:19 PM >> To: World Wide Six Meter Club >> Cc: Roger on six <50MHz at rogerhalstead.com> >> Subject: Re: [SixClub] Gonset GSB-6 6m Transceiver? >> >> Roger, >> >> So far I haven't found a schematic or manual online, >> so I can't see how they are getting things done in there. >> >> David KD4E > > ______________________________________________________________ > SixClub mailing list > Home: http://mailman.qth.net/mailman/listinfo/sixclub > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:SixClub at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html
