Pro-120 series Mk 2

Issue number history

In early 2003 we released a redesigned Pro-120 controller. However - in general it's such a popular and good controller that not a huge redesign was possible! The main change is that it uses sub-miniature resistors, to give room to add alterations!

Etched in the copper of the Pro-120 Mk 2 is a number such as 30-3B-2-04, there the '04' is the Issue number of the circuit board.

The table below links to the issue numbers.

01020304

These are the features that are added:

Pro-120 2 Issue 01

Pro-120 2 Issue 02

June 2003. Most of the changes are minor tidying up of issue 1.

Issues 1, 2 and 3 are now too old to qualify for factory serviceing.
