#2219 — VTX5000 modems

I have not forgotten these. the sad fact is that I've now run up a few of 
these and not one of them has powered up successfully. All make a nasty phut 
noise and a little crack and then lock up the speccy. The source of a 
noxious smell has been traced to a tiny tantalum 'bag of resin' type 
capaacitor which is across a supply rail on the edge connector  inside the 
box. The obvious  conclusion is that these capacitors have gone leaky 
through disuse and damp or whatever and sadly all will  have to be replaced, 
but I have my doubts if any other capacitors of a similar kind of which same 
are visible I gather, will be in the same conditon. and really its going to 
be an issue A: getting them all changed  or to supply as is if someone blows 
up their spectrum buy tring to run one.
 Thoughts?

Haven't seen any followup to this. The capacitor issue should be easy to 
fix, even if there are others of the same kind. Do you still have the 
defective modems?
