I don't know if this is techinical, but any suggestions would be appreciated.
I acquired a Viking II that had been sitting for a very long time in a garage/barn.
The transformers, insides and chassis are not in bad shape.
The case is bad, especially the front.
The logo and some areas are corroded down to the copper color.
Oddly enough, the corrosion seemed to have missed the lettering which is good.
I'm not sure yet what I will do as far as the case..
Get a used one..paint it black krinkle and call it done?
I've replaced the caps and some resistors thus far.
I've managed to get two knobs off thus far (10 to go.)
The 10 remaining are rusted bad..real bad.
Anybody have an idea for removing rusty knobs?
I'm talking RUSTY..
The bakelite is good and should polish up nice.
Hate to mess them up doing something that would damage them.
It was abused but I'd like to get it on the air.
I have an HQ-129X to mate it with.
Thanks for any suggestions.

Try a couple drops of marvel mystery oil. Take the set screw out and put a couple drops in the hole and let it set a couple days

I suggest a 50-50 mix of lacquer thinner and ATF.
Works and penetrates like a charm, eats rust.
Let soak for several days on the set screws... once the set screws are out it is easy.
As said, drop in the hole and let soak...

laque thinner may attack the finish on the knob but ATF is a good idea

The auto dealers may help here... Mopar has "Rust Penetrant", GM has "Heat Valve Lube", both are the same stuff, very effective! (freed up a frozen 318 for me in 2 days, and ran just fine afterwords!  ) Norm K7NCR |

Can't argue with any of the suggestions here so far. I have had very good luck with simply douching the shaft and the set screw with WD-40 and then letting it sit for a few days. If it still doesn't free up easily, I douche it again and wait another few days. That's always done it with my Johnson...

One thing I'm certain of is that there is too much certainty in the world.

My Dad always had a little bottle of p oil for these kind of problems.
I've seen it in spray cans from auto parts joints.

I tried some good penetrating oil that normally works for almost any rusty mess, but no go. Even tried some turbine oil [in very small drops] with no good results. Ended up using a screw extractor on 2 before it broke. Really rusted to break one of those. Finally ended up completely drilling out the set screws on 2.
