[Hallicrafters] SX28 Restoration

[David Woodhead]

I have been wanting an SX28 for some time now and today was my lucky day - I picked up a very rough looking specimen for $25! I've given it a quick glance over and have a few questions for the group:

1.    S-meter housing has split in many places. Are replacements available? Perhas salvaged from a particular brand of meter?

2.    The main tuning shaft looks to have been knocked (bent). It appears that the shaft with the main tuning knob rides inside an outer shaft (with metal dial plate on it). Tuning is very rough and slipping. I will completely disassemble the gear train anyways but is this shaft assy serviceable? Is it a ball drive (gear reduction)?

3.    The RF cover (top, sides and underside panels) are badly rusted in places. The chassis itself looks to be OK under the thick layer of dirt! These pieces will probably need to be sand blasted and replated. Anybody done this? What kind of plating is it?

4.     All the knobs are original except the AVC knob, anybody have a spare?

All of the aluminum parts are covered in a thick layer of white corosion that will need to be removed. The dials are in fair shape, not cracked but do have a very light blotchy appearance that looks to be inside the bakelite or whatever they are made from.

Most of the underside is original and will certainly require many new caps and resistors. The Audio o/p transformer might be replacement - mounting

Thanks for any help/suggestions.

David.
