I'll certainly second what's been said. The goop on the cabinets may
well be removable with some of the current cleaners (to include
Goof-Off, used with care!). You might even consider un-building the
unit and clean the chassis up completely. The front panels don't look
bad, at all, and you'll end up with a nice set of equipment. One can't
judge the effort based on the dollar value of your time.. you'll lose
that trade-off in a heart-beat! Its the fact that you did the job and
the results that count... Give it a try. Any bad parts you might find,
except maybe the power transformer, are readily available. Those two
units are an ideal entry point for the restoration process....... de K3HVG
