Hello everyone I am hoping that some one on here can help me out!
recently purchased a used titan 425 ran great the first week ! although the
meter lights were out .
28ma 1300-1500 out opened it up the bulbs were 12 volt in series replaced them
closed the cover back up
powered it back up meters light up it wont key up??
tried removing the bulbs no joy replaced Q1 and Q2 on the bias board still no
joy
checked all of the relays K5/K4/K3/K6 they all close when powered directly bias
on terminal 85 on the bias board reads 8.5 volts all of the time.
relays K5 changes state when you switch from standby to operate
28 volt source on pin 7 from ps reads good
meter reads approx 2.4 kv when in ep??
at a loss here hopefully some of you gentlemen have some clue as I sure don't
would also be interested in purchasing a used but good bias control board
Thanks And 73's Martin KN4DXD
