Try, www.ne7x.com/sb200/heathkit-sb200.htm at the bottom of his page will
take you Conversion to 6 meter. I been using the 1969 modifications only
with 10 meter not 40 meters for over 10 years now and with good tube I get
500 plus watts with 60 watts drive. However don't use Taylor tubes in a
SB200 filaments will sag and short out filament to grid and will cause you a
lot of problems trust me..... WA0KBZ Bill
