I have the list of parts ordered at Tritronics. Most in stock, some back
ordered. I ordered two of each for CYA's sake! I think I will just try
it. It's possible a line surge did it, or could be a fly. I faxed sanyo
technical saturday, but they are notorious for returning the fax in a
week or two. Like a shop is going to wait 2-3 weeks.(or more accurately,
the cuss-tomer). I gave them all my bad parts and asked what would do
this(such as a known issue like a fly,etc) To date no answer.
One time I actually had them fax me back a month later on some simple
thing. Gads what are they thinking!
