John, I'm going to have to print out your papers and try it again. I'm not sure, but I think the display was flashing "10" then went to regular play mode. Then it will take selections, pull the CDs onto the player,and act "stupid".
I've never had symtoms anything like that, that wasn't cured with a new/rebuilt player so I didn't pay much attention to the number.
At the moment I can't think of the name of the only guy I know in the US........................ It just came to me, well sort of. It's something like Rob Stapleton. Does anyone know who I mean? I googled him a couple ways and came up blank. Not to put down John, it's just that the guy is in the US.

Hi Tony,
If this is a CD-Pro then it has a controller board in the CD chassis, have you verified that it is working correctly? What code numbers does it display in sequence when it the machine is powered up.

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?
