Major Havoc R186 missing on boards

Along with some manuals I bought from an op, was a Service Bulletin
regarding Major Havoc.

1. Resistor R186, a 1k ohm 1/4 watt, is missing on some Rev B Kit
boards. It is located near the LETA chip (137304-1001) at location 12N,
underneath the Quad Pokey Adapter board on the main logic board. The
symptom if the resistor is not loaded is very slow movement of Major
Havoc by the Whirley-Gig. The added resistor doubles the response.

So far both boards I have looked at are missing the resistor. You may
want to check your board, a .01 cent part could be causing slow
response.
