Title: VR values on CD systems.
Post by: atman on 05/09/2017, 04:29 AM

Managed to damage the VR103 pot on my Duo when I was removing the C133 cap. Thought it was out of alignment but it was permanently damaged.

I had a moherboard from a Super CD-rom that I had laying around. Took the VR103 from that one and it seems to work.

But, its a rather old VR, are there any schematics on the VR, are they the same values and what values are they specified?

No schematics or anything but maybe these links will help.

Thanks!

Noticed that it was a reason for the super mini pots, had to put wire on the bigger pot and hide it on a better place.

Think i'll order a set.
