Currently restoring a 37-116, have the following options re: chasis
Replating the surface rusted metal tube shields with
1)Tin 2)nickel 3)silver 4)gold 5)copper 6)Brass
They are originally tin plated, however, even though this would be true to form, it's not the best coating for corrosion protection.
Would one of the other metals diminish the value? Which would you pick?
Also, as I haven't fired it up, is it best to bite the bullet and recap the whole thing (ugh!), try to reform the caps (need to buy/build a high voltage DC supply for this)... reform in circuit or individually? I've read the reforming threads... sounds like some work to do it right... but still easier than recapping the whole unit. The tubes appear to be original, w/o much filament transfer, so I'm hoping they'll fire up eventually
Thanx for any help...
