I was planning to offer refurbishing service for failing JOBO processors. After a lot of deliberation and looking for available parts which could be used, plus a very close look at the postage costs, I decided that such a service would not be economical - which you indirecly proved, since you bought yours (in a good working condition) for $150 - which is waaaay below what I would charge for refurbishing - and when you add the shipping costs, you see that it's a service which would be way too expensive.
So, in a nutshell, I decided NOT to offer such service, on the grounds that it would be too expensive.
Sorry, I had not read all the posts in the thread. My apologies.
