Hi;
I am trying to work out something to try and get my Aztarac project back on track and was wondering if the 6400 was med res?
I kinda remember that it is but it has been so long since I did the research and I cannot find my notes on the CRT, that I do not remember for sure.

Can anyone confirm that this was indeed a med res, or at least tell me it is not??

Thanks in advance
Jeff
 
If it has the 19VLUP22 tube on it (standard for the 6100 series) I would think it is standard res. My train of thought on this is that the Amplifone has a better picture which is attributed to the med res tube....
 
Concepts like "standard res" and "medium res" don't apply to vector chassis. Sounds like you're talking about dot pitch.
 
Yes, I guess you are right, "dot pitch" is what I am concerned about.

I checked the 6400 manual and it lists the 19VNJP22 as the CRT in the monitor, does that have the same "fine" dot pitch, same as the Rouland found in the MH, SW and Quantum vs. the "large" dot pitch as in the WG6100??

Thanks
Jeff
 
The 6400 is the same as a 6100, but with a more solid chassis design. The difference between a 6102 and 6400 is very, very little.

It'll be a challenge to build an Aztarac monitor from scratch. Never say never, but the 6400 is more different than you think. Yes the basic circuit is similar. However:

6400 is powered by a 40-0-40 transformer (closer to a G08)
6100 is powered by a 25-0-25 transformer

6400 X and y max input voltages are 4v and 3v (again, think G08)
6100 X and y max input voltages are 8v and 6v

Yoke is different, "May" be interchangeable with a G08-105 if that's any easier to find. Obviously tube is different, higher resolution. Good news here is that you can swap in a M48AAW00X Amplifone tube.

I made an XY monitor reference guide years back. Francis still has it up on his site.:

Wrong, In so many ways.

First off the picture tube in a 6100 is a 100 degree, the 6400 is a90 degree.
The output transistors are doubled up from 6 to 12 in the 6400.
the 6400 uses a input board that mounts at a 90 degree angle. thus a completely different deflection board.
different neck boards.
different deflection coils
the 6100 uses a 15 pin mloex connector, while the 6400 uses a 12 pin.
the HV units starts off the same, but had mods done to it including removing the 8 pin connector.

about the only thing that is the same is the metal frame...

Thank you for that detailed comparason.

BTW, I have been searching for both (either) a 6400 and a 105 for quite some time with not even a luke-warm lead. I figure eventually, in a couple of decades, after us collectors start dying out, a widower will be liquidating her husbands collection and I should be able to score one then, if I live long enough!

Clearly, the information I was provided and was referencing was incorrect. Thanks for the technical corrections.
