I've always been a sucker for lost causes and high tube
count
boatanchors, so when I came across this SP-600 I had to
have it. This beast had been sitting on the floor of a
damp garage
for decades unprotected. I spent 3 hour cleaning out
mouse
turds and black widow webs.
Take it outside and hose it off. You wont hurt it. If you
need parts email me.

I will pass along a method of cleaning used at
Hewlett-Packard many years ago. We washed equipment sent in
for overhaul using a paint spray gun filled with warm water
and dishwashing detergent. This, along with a soft brush,
would remove most dirt and junk. Once washed the equipment
was rinsed off using a sprayer hose attachment and dried in
an electric oven for several days at about 130F. Remove
anything that can be damaged by moisture, meters for
instance. We also found a high rate of failure of
hermetically sealed transformers and chokes. This is
counterintuitive but if the seal is leaky moisture can get
in and has a hard time getting out again despite the baking.
I don't know what effect this will have on the ferrite cores
in the SP-600, maybe none.
