Paul,
I did some investigating and some testing. First, two of the three
bulbs were bad. I cannot get these locally, so I have ordered both
meter and switch bulbs on the internet and they will arrive in a few
weeks. Meanwhile, I put the good bulb into the standby switch, and it
turns out that the delay appears to be working properly--the lamp lit
after a few minutes warm-up.
Now comes the bad part. I connected a dummy load to the amp RF output,
and I connected the exciter rf to the amplifier (this is the first time
that I have done this), and I connected the exciter relay switching to
the relay connection on the back of the amp. At this point, I saw that
the swr on the exciter swr bridge was high. I double-checked all
connections, and used the same cable to connect the exciter directly to
the dummy load, where the swr was 1:1. I then thought that perhaps
there was a stick relay in the amp, so I went ahead and connected
everything back as one would expect to use th amp. I pressed the CW/Low
switch on the amp, and I turned the exciter power to zero and turned on
the exciter, and then brought up the power a little. I saw some grid
drive at the amp but no plate current. I unkeyed, turned up the exciter
a little more, and the grid current went up a little more, still near
the bottom of the meter. I repeated this with a little more drive (the
exciter still showing a high swr, and this time no grid current showed.
I turned the amp off, and again checked to see the swr at the exciter;
it was still high,despite the fact that it should have been looking
directly at the dummy load through the amp switching. Then I wrote this
e-mail.
