Hello All, Take a look at W3BYM's pair of 813s modulating a pair of 813s.
A VERY robust, well designed, engineered, AND FINE sounding Homebrew! The entirety is available in Electric Radio Magazine http://www.ermag.com/ My recommendation would be to get the ER back issues. The price of back issues is $3.75 ea. The specific issues are: Number 153 - February 2002 Number 154 - March 2002 Number 155 - April 2002 The text goes into design considerations, parts selection, specific transformer information/identification, and tap selection. Also issues as to modification of the B&W 850A bandswitch/coil assembly. -- Bob - NØDGN +------------------------------------------------------------------+ | \\"""// CraftyBob - WitchDoctor \\"""// | | (@ @) Bob Bethman - NØDGN (@ @) | +-------oOOo-(_)-oOOo--------------------------oOOo-(_)-oOOo-------+ | NØDGN AMRadio Manassas, VA | REAL Tube Radio and AM | +-------------------------------+----------------------------------+ | Manassas Radio - Home of Homemade Kielbasa & Pirogi | +-------------------------------+----------------------------------+ | Bob Bethman \\\|/// " The absence of a danger | | rbethman(at)comcast.net \\ ~ ~ // signal does *NOT* mean | | (/ @ @ /) that everything is OK " | +-------------------------oOOo-(_)-oOOo----------------------------+ | <http://home.comcast.net/~rbethman> | | 1 BC-61ØI w/BC-614I,1 T-213/GRC-26 w/BC614I,1 '51 Collins R-39ØA | | SP-6ØØ/NR Type 159, Heath DX-6Ø, Apache, Mohawk, SX-1Ø1, HT-32A | +-------.oooO---Oooo.---------------------------.oooO---Oooo.------+ | ( ) ( )Opinions expressed are that( ) ( ) | | \ ( ) / of my own and do not \ ( ) / | | \_ ) ( _/represent those of ANYONE else \_ ) ( _/ | +------------------------------------------------------------------+ | Amateur Astronomer - Celestron Nexstar 8 & Meade ETX-6Ø | | 38 Deg 46'48.62"' N - 77 Deg 28'26.89" W | +--------------------------.oooO---Oooo.---------------------------+ | ( ) ( ) | | \ ( ) / | | \_ ) ( _/ | | ALL E-mail received and sent scanned by AVG | +------------------------------------------------------------------+ ______________________________________________________________ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected]
