Marquee Stuff

We will look at and I'm hoping to understand myself why the focus was improved on my 9500 when I made some changes to the Stig Waveform and Stig Amp boards with only a few changes made to the CLM -- Hocus Focus!

In this thread I've posted waveform patterns from the original Electrohome tech data. I will also be showing what ringing looks like on a scope, and what it looks like on my test HDM in comparison to the waveform from the tech data.

After countless hours of scoping around in the Marquee chassis, I've concluded that adding that ground strap, not only cleans up a lot on the scope, it also solves the well known "oscillating Stig Amp board" problem. As well, as correcting several smaller problems caused from the vertical deflection module.

Just a few of the things I've done to two of my personal Vertical Modules shown in the following images.

The same gamma circiut mod I've done for the G90, I'm also making happen for the Marquee.

This gamma mod will greatly improve on the existing gamma mod on the VIM.

It is a very precise and controllable gamma circuit, that uses the sync pulse for accurate performance, unlike the existing gamma circuit, which does not produce a high performance gamma curve.

Coming soon!

I will be showing a test probe connected to my Test unit, and possibly how to set and adjust the HV.

In my spare time I've been working on modifying the filament section of the LVPS.

Two things I'm looking to accomplish: 1, a cleaner 6.3 vdc for the tubes: 2, removing the 4 vdc filament voltage to the tubes when the projector is not powered on.

Special Access

How to purchase

This is for the single VIM modification of either the 20-2035-02P or 03P VIM.
This mod will only be offered based on your system and setup. It is very important to have a good HDMI source device and CRT's in your PJ for best performance.
The sale would involve a stock VIM being sent to me in exchange for the finished and tested VIM that I would be sending out.

This is a very special mod package that unlike the VIM only mod, it includes all three neck boards included with the Super VIM mod. This complete package offers an increased performance over the stock boards, but for the most discerning viewer only.
