Any help would be greatly Appreciated Thank You Radio Amateurs Handbook any copy printed between 1963 to 1970. Also back issues of QST for that era. A tube TRX for SSB will minimally be around 11 tubes or more and not simple. "Just finding items like the power transformer will be a challenge." NOPE, that is urban legend BS or must be working for a Far East exporter (Purpose of the "weak dollar" is to strengthen these mfg. in world market - not kill them). Just in greater Chicago area there are at least 3 major mfg. that have been around for 75+ years -- and turning out hundreds a day plus custom requests. Triode Electronics JUST handles the Dynaco rebuild requests -- they are providing brand new units exceeding original 1950 specifications (better materials and mfg facilities) http://www.triodeelectronics.com/ Heyboer - Grand Rapids, MI http://www.heyboertransformers.com/index.shtml Heyboer also handles the profesional musicians/bands/professional restorers/audiphile market -- that still use vacuum tubes for that soft warm sound! http://www.heyboertransformers.com/tubeamps.shtml There are a LARGE number of US transformer manufacturers -- USE the GOOGLE with the Internet!! If you can find an old Heathkit HW32 (Monobander SSB series) and rebuild it that might work better. Yes, that is a viable solution for a tube based radio. A solid state design is also possible. gb |
