There is a mod on the A model which was fixed in the B version.

I saved a bunch of 5370A boards from being sent for gold scrap at a

as far as speed goes, and you can use the A or B
virtual roms as you wish.
The principle difference is the B analog boards are
easier to
It's not practical to convert an "A" to a true "B" model. They use a different

firmware runs on a "A". John's CPU board works on either version.

List,
I won a 5370A from ebay. Though it seems to be missing the A channel level
knob, the unit was shown powered up with the correct 0.0 on the display,
although the unit was sold as non-working for parts or repair. But the price
was right with a best offer accepted.
So assuming (gulp) that th
