813's You transfered me back in the fifties TOM
Are these valves still available or used ?
Remember I had a TX on board " Algerine Minesweeper " 6V6 gt as an
ocillator, 807 gt as a driver and 813 in the PA. Never blowed one up. Even
when using portwave in harbor we just took the ant.off :-). Dont try it
nowadays without a good protection...
Thanks TOM for the trip.
Jos
