To all those who have provided leads for meter repair, I thank you. I am
following up on those leads.
To the others who posted and were probably shaking their respective heads in
disbelief that I was working on the SX-17 while powered up, I have this to
say.
First, if you are not familiar with the SX-17 chassis layout, other than the
"S" meter terminals, there are no other live terminals or exposed wiring
when working from the top of the chassis. So, I felt I was perfectly safe
with what I was doing. I also had the mind set that I am working on a tough
boat anchor with no real possibility of damaging anything. I mean after
all, this thing weighs about 50 lbs. This I admit proved to be wrong. The
one item that could be damaged was. Murphy is involved here.
Second, the steel cover that goes over the main tuning capacitor must be
removed to perform alignment and calibration. It allows access to the
trimmer pads. In order to check the effect of the alignment with the cover
on vs the cover off, I needed to have the receiver on and warm to avoid
initial drift from cold start. So, the rest is history. The end of the
shield cover hit the meter terminal and probably opened the coil. This "S"
meter is in the plate circuit of the meter tube. So, basically, I shorted
B+ to ground through the meter.
Live and learn, but I will repair this receiver, count on it.
