here a re a couple of pics of a relic I took out last week.

this was put in service in 1983 and has a date code of 1981. I personally worked on many of these for many yrs. this was the last one to be removed from a site and was still working but not live to an antenna. it was left as a backup when it was replaced by an MTR in 98 or 99.

Nice, that is a name from the past!

 

I am currently working with a radio shop doing inventory on all his unsold, traded in radio gear, plus a slew of UHF mobi and base antennas to sell off on eBay. 

 

Walking through the warehouse was like going through a museum, I love seeing old gear get new life.

I did a quick check before I pulled the plug. Tx was 1500C high rx was .5uV. I didn't check to see how far off the Rx was though. was set at 50W but it was set like that for yrs, was rated for 90W. we almost always set them to 1/2 power. I'm probably the only one still left in the shop that know the little idiosyncrasies of this particular brand of machine.

John - When I first read the title of your thread, I thought that you were speaking of anyone old enough to know what a vacuum tube is and how it works...LOL... ;)

Speaking of vacuum tubes, I had the "honor" of working on an "ENIAC" [ Electrical Numerical Integrator and Calculator ]  in Chicago in 1966. This one was one of the late production units having "only" 1900 tubes. It was in a room 26 feet by 16 feet and had it's own air conditioning system. Even so, the average room temperature was around 85 degrees and no joy to be in there for any length of time.  It had the problem solving power of a 1982 Commodore 64.  But at least it would do something that a Commodore would not do... the operator could cook lunch on the wire mesh case surrounding the power supply tube type 2X2 rectifier bank. There was a sign near the operator's desk that said, "Bring your own frying pan."

 

:D
