Thanks Malcolm...very good post!
Hope you don't mind but I forwarded this to an old friend of mine
who has the 'flickering digit' problem on his Corsair 2. Very good
info!

Salut everyone,
Nice to see the reflector hackling well. Quite a few members with
their hackles up as well!
Being only a humble Corsair2 owner, have rejoined to impart a piece
of information. Lost the display readout on power-up just after
completing the WPX cw contest. Ten-tec always prompt with advice
could only sugeest pluggery or dry joint. After re soldering the
entire display board, the fault persisted. With digital probe I
narrowed it down and found C28 2.2 mfd electrolytic, Pin 28 on U10
display micro-controller suspect. Changed it for 1mfd tantalum with
immediate result, a rock solid display. Have seen various Corsair
display complaints over the years especially on the flickering green
100 hz readout and am sure this may be due to a deteriorating C28.
2. On rig comparison, my other is a JRC JST135 chosen for it's
excellent receive qualities. On receive the Corsair beats it hands
down and renews my faith in this wonderful old lady which I rate one
of the best cw contesting rigs ever.
3. I have owned two Corsairs, the original is now kept for spares.
Since the start I have done all my own repairs right up to PA final
transistors and am willing to help out if anyone has any Corsair
queries direct to malcolm.mcleman@free.fr
Best regards to all,
Malcolm/F5VBU/GM3UIN
