The Rev 2.0 boards are in and orders are being filled.
One of the most frequent failures of the Wells Gardner 6100 series XY color monitor is that the low voltage power section of the deflection board fails.
Anyone who owns a Tempest, Space Duel, or other Atari color XY game with
a WG6100 in it has probably seen this problem. Something in the HV fails,
or a deflection transistor shorts which causes runaway currents to be drawn
through the low voltage section which in turn burns out the small regulating
transistors Q100 & Q101 and some resistors!
Heck, sometimes it just decides to fail for no reason.
We have designed a low voltage retrofit, the LV2000, which eliminates this problem. This small PCB (1" x 2" in size) replaces all the components of the regulating part of the low voltage section. The voltage is adjustable with two small potentiometers and there are two LEDs indicating that the low voltage is being generated.
The only parts that do not get removed from the low voltage area are the large filter capacitors, the 4 diodes, and the power output transistors.
With the LV2000 retrofit installed, the low voltage power section of the deflection board will never fail. If a deflection transistor were to short, the over current drawn will not affect the LV2000. So you could install an LV2000 once and not worry about having to replacing the low voltage components every 6 months or so.
