I find myself a TV tech, getting dumped on with older HAM rigs for
repair by newbie licenced HAM's with no vacuum tube experience.
I am in need of a decent 50 or 100 watt dummy load to properly align
the transmitters at full power.
I have stuff for trade or am willing to pay up to $20/USD for one
shipped to Canada, postal V0X 1X0.
Outside of the usual ones on e-bay , as long as it is a tube transmitter
you can use a 100 watt lightbulb. While it is not a very good 50 ohm
load the tuning of a transmitter should let it work.
That's what I ended up using after I boiled the water in my
immersion-cooled 47R/2W resistor, but didn't know if that was sufficient
;-)
Thanks.
