re:The old AC- CHT
probes and all engine gauges in the old Bo's....new probes no longer
available, must change out to new gauge and probe according to Beech.
HOWEVER:  Instrument Technologies in Dallas, TX will sell you a probe with
matching resistor to use on your older CHT system, retaining the old
gauge...allot less cost than a complete change.  Also, has the know-how
(repair, parts) to keep your original AC engine gauges working in lieu of
replacement with new Rochesters.  Instrument Technologies  800-229-9078
