[Kenwood] TS-790 A display problem

[Clif Holland]

Yeah, that thing is worse than the old TM721 display, at least you could 
make it out with a flashlight. If you put in 12v bulbs and they work browse 
around, there is 12-14v all over the place...

Thanks very much, Clif.  You always have the right answer.

It uses 6 volt bulbs, and I only have 12 volt bulbs with the wire leads.
So I used the 12 V bulbs with an external power supply to get the bulbs
lit properly, and lo and behold, the display is there.

Here I thought I had a real problem, but I am certainly glad to know
that it is indeed very minor.

Thanks, Clif, and thanks to the list.

73,

Ken, W8EK
