By the way, I would guess this is the correct hand unit. Unfortunately it's rather expensive. This is one I don't have.

these were good sets, I wouldnt mind working
on them all day. Easy first. If it has a headphone jack plug one in & see if it works. Also jacks go bad & get cold solder on them if they are used much. Speaker..... Unplug it & hang any old speaker in. After that will have to dig in. See if you can find the chassis number. Starts with TAC #### On a black & silver label probably near the HV trans. I can see if I can find something close. 73 Zeno

Here's the audio section and the control board - the volume control is at the bottom..

It still could be a bad jack - the plating tarnishes, creating a high resistance between normally closed contacts - plugging a earphone in and out a few times will usually do the trick, else some Isopropyl Alcohol and a soft brush.
Does the speaker have continuity? Start there, and work back to the jack - a pinched wire, a loose/off terminal on the speaker...

If the SPKR is bad you may have a hard time finding
an exact fit. You will be able to mouse something in. We can cross that bridge when we get to it. 73 Zeno
