I have a customer who swears his OMT was brand new when he bought it.
Someone else before me upgraded it to a CD Pro when the older ones
stopped working. I temporarily lost the serial number, but it fell
within the range where all the BC 337s needed replacement.
Looking at the credit/control board... it appears that all of the
transistors were replaced, including the BC327s. Or who knows, maybe
they were all removed, tested, and replaced with the old ones? I can
tell by the soldering and the rosin that they had been soldered in again.
Anyway, it won't play a CD. It looks like the usual bad CD player
problems, in and out, spinning erratically then returning it to the
carousel. A good working player acts the same way, and the player from
it works fine in my test box.
So should I assume someone did indeed "test" the BC337s and put them
back in? I have plenty of 2N2222s to replace the BC337s.
To make things worse, I don't have a Wurlitzer to test it in, and it's a
little over an hour away to the customer's house.
Any ideas? Words of wisdom? Change the transistors and take a trip there?
