| Subject: | Re: Compass Amplifier Tubes |
Re-seating the tubes fixed the problem. I have a source for one of the
tubes. I do not believe that the other one is a 6X6, since that tube really
doesn't exist. It's either a 6k6 or a 6x?.
If anyone knows about tube nomenclature maybe you can help.
Thanks

Ernie, try spraying a good lubricant down the brake cable into the housing, while
working the brake handle. You will be surprised how easy the brake gets. That
is only if the cable is good. If frayed, don't bother, just replace.

For you old guys out there that need reading glasses, I just came across
the greatest thing since......well reading glasses. They're called Hydrotac
OPTX stick on lenses. They're designed to stick onto regular sunglasses to
give you bi-focals, but lo and behold, I just stuck them to the inside of
my visor and voila' I can see the gauges and still look out the window.
I bought them on Amazon for $15.

Thanks Gary, I knew I wanted to do something when I got home, and you just
reminded me, look up "Spray Graphite Cable Lubricant" I used to use it on
my moto cross bikes when I was a kid.

| Subject: | Re: Pressure Problem |
Hi
I see mention of the compressor building pressure a bit while taxing?
I also saw in the manual that the charge rate is approx 8litres in 30 minutes at
60%.
At what percentage do the compressor start charging and will it charge faster if
the RPM is higher?
We have a problem where the compressor don't seem to charge but I don't know if
it will only visibly charge enough while in the air or also on the ground. ie.
50% for how many minutes, etc?
There is no audible hissing sounds with gear down.

| Subject: | Main gear soft after landing |
Hi
If you hang and pull a wing down say the left side, it is normally a bit difficult
(stiff) and then becomes easier and easier to pull up and down. After a while
of leaving it (say an hour or so), it is stiff again.
After a landing the same thing. Sometimes left, sometimes right.
Is this normal or need some nitrogen? The gear/oleo's on both sides were overhauled
last year.
I am thinking that if you maybe land a bit more on the left side, the left side
get pushed in a bit more and then will be softer than the right side and otherway
round.
Or might there be a problem to attend to?
regards
paul
