The cat slept atop the '610. Not the Model 26. (;-) There was a 5 KW PA made in an almost identical cabinet.
Sold my '610 to an off-shore navigation company in Louisiana for $300. They sent a man in a PU to Oklahoma to get it. Last heard it was operating 24/7 in the 2 mHz just above 160M. Still have a set of PA coils in attic. 73! K0PP On Fri, Mar 22, 2019, 10:26 AM Ken G Kopp <[email protected]> wrote: > I had a Teletype Model 26 attached to a BC-610E.
