TS440S front panel and tuning dial removal
 

remove the rubber grip by sliding it off the front of the dial, then losen the
screw on the dial. I'm pretty sure it is a hex head.

I need to remove the front panel of my TS440S to clean out the
pushbuttons (some are too "bouncy").

I see there are some screws on the side, but I suspect there are a
couple under the tuning dial knob.

How does one remove the tuning dial knob? Looking at the screw head,
it doesn't look like a hex screw.

There are two screws behind the tuning knob, but it's not necessary to
remove the knob to remove the front panel You can remove the knob by
inserting the appropriate size Allen wrench into the hole in the knob.

What's the proper size allen wrench?

How do I remove the front panel without removing the knob?

Tnx!

1/8" fits mine.

In order to get to the push buttons you're trying to work on, you have to
remove the face panel which swings down from the front of the rig once you
remove the necessary screws. You might find it's a little rough going cuz
things are pretty tightly packed in there. I've been in there to replace
the meter lamp twice in the past 15 years and it's tight.

You'd do well to see of you can locate a service manual. It'll make the
task easier. I learned the trial and error way to get in there.

I went and bought a metric set. Turns out 1.5mm fits perfectly well in
my case.

Well, I did remove the front panel, and it was relatively easy to
get to the PCB that has the switches.

These buggers are a paint to work on, however. They're membrane
switches. I carefully lifted the clear mylar, and slowly removed
each membrane, and cleaned them off individually. I also cleaned
the copper pads on the PCB.

I'm taking a break from all of that as I type this...

I have it, it came in the mail today, after I was about 1/2 way
into the disassembly...

Your comment about the lamp is making me wonder if I should do a
preemptive replacement.
