Default Tech Review: Victor's (8liners/Genao) Replacement Arcade RGB Monitor Chassis (LONG)

Hey all,

I purchased three high impedance chassis from 8 liners because I
had three dead or non-working GO7's.

First off I'd like to say I'm no monitor expert, but I have done
some cap kits, flybacks, transistors, etc. and am learning all the
time.

The first chassis I hooked up I mixed the vert and horiz and popped
a cap on the board. Do not do this. This is bad. I contacted Victor
and he said he would repair it for $20. I thought this was very nice,
since I was the one that let the smoke out.

The second chassis I installed correctly. The picture was very
nice and crisp, good color, good adjustment except the horiz width did
not work- just spun freely. The only problem was that the image was
bowed in about one inch on the left and the right (monitor mounted
horiz). Like this ) (. There is no adjustment for this I used this
chassis one all three tubes with the same results.

The third chassis was exactly the same as the second on all three
tubes.

I also have a known good GO7 chassis that I installed on all three
tubes that worked perfectly in every case.

However, my test game is a MAME machine running with a JPac. The
JPac has a video amplifier built in so I still question if this may be
the cause of the bowing.

When I have more time and a good canidate I'll test these chassis
in a regular game like my Ms. Pac. I attempted it in my Robotron but
there is no provision for it to sync to this game.

Apart from the bowing (which IMHO is intolerable) it's new, cheap,
and a time saving remedy for your 20 year old monitors. Perhaps one
of you monitor guru's out there may have a solution for this problem.
I am willing to provide one of my chassis as a test bed. So please
contact me if you are interested.

Thanks.

,Bill
