I also built several heathkits transceivers, back in the late 70s. now, mostly do 2 meter fm. thanks for the shout out. pigpen51https://www.blogger.com/profile/07447842175184001919noreply@blogger.comtag:blogger.com,1999:blog-5837660608809488753.post-9493186659308004212015-07-13T07:04:45.900-04:002015-07-13T07:04:45.900-04:00Rickn8or, thank you!
Pigpen51, I have been a ham ...Rickn8or, thank you!<br /><br />Pigpen51, I have been a ham off and on since I was 15 and a radio geek since age 12. Much of my interest is in older gear, though I have (and use) a couple of Ten-Tech 540s and their Scout 555 with all the modules. All CW so far; I've got a little AM rig on the workbench now and some bigger ones in the queue after it.<br /><br />Joe: Modern multi-match output transformers would simplify building the power stage around something a bit odd -- 6BG6, perhaps? -- and subbing 6L6s later if desired. I've long believed the overload characteristics of 6L6s and KT88s were responsible for much of the warmth in electric guitar sounds. Jensen Transformers have some interesting preamp circuits on their website -- cascodes, etc. -- that are worth looking into if you'd like to chart a different course on the input/driver side.<br /><br /> And for both Joe and Pigpen51: I've long harbored a secret wish to build a 1920s-style ham transmitter around one of the (repro!) WECo 300B audio triodes that are so highly spoken of by audiophiles. It's probably the last of the classic power triodes still in production.<br />Roberta Xhttps://www.blogger.com/profile/09956807794520627885noreply@blogger.comtag:blogger.com,1999:blog-5837660608809488753.post-66976237857186708702015-07-13T02:41:49.832-04:002015-07-13T02:41:49.832-04:00Tube amp semi nerd, of the guitar playing fraterni...Tube amp semi nerd, of the guitar playing fraternity here.<br />Always pondered putting a bit of effort into designing a circuit around some of the lesser known and used NOS tubes floating around.<br />It would be a fun idea, but, the standards are standard for a reason, and the new production Tung Sols/JJ's/ et al work well enough for my musical level.Joe in PNGnoreply@blogger.comtag:blogger.com,1999:blog-5837660608809488753.post-28019986531842470862015-07-12T18:55:52.854-04:002015-07-12T18:55:52.854-04:00I never realized your were a ham nerd too.
