27" tube has measures ~ 1 ohm across the horizontal, problem?
AceTKK:
I picked up a beautiful 27" tube from a t.v. shop as a candidate for an 8-liner chassis swap. Upon getting it home and breaking out the multi-meter I found readings of ~6.8 ohms across the vertical and ~1 (or maybe even a little less) ohm across the vertical. Now, all I have currently is a super-cheapo Wal-Mart analog Multi-meter so it's accuracy is questionable. I guess my question is does a 1 or <1 ohm reading on the horizontal indicate a problem with the yoke?
thx,

I wouldn't trust a cheap consumer analog multimeter. Go to Harbor Freight Tools if you have one, and pick up their cheap digital multimeter. Normally $9.99, on sale this week for $4.99 and often on sale for $2.99 Even includes a transistor (PNP/NPN) tester on it. Also make sure you have a NEW 9 volt battery in any DMM, otherwise it can give incorrect readings I've found.
Scan the forum for my post about a 23" tube with a 7.8 vertical and 1.x horizontal. Ken felt it might have pincushion problems on vertical since most 25+ chassis assume 9x as the low end.
I am not going to try the 8liners (I already tried their 19" and posted results at oscar's site) and am instead going to go with the other brand of chassis. I just havn't gotten around to ordering yet.

I've got a 32" tv with a .8 on the yolk, still works fine as a tv.
It's not compatible with the 8liners chassis.

AceTKK:
Dabone, did you actually try an 8-liner chassis with your tube (do they make a 32" replacement chassis?) If so, why wasn't it compatible? Pin-cushion problems?
Yea, I think my first step will have to be picking up a better multimeter. According to the 8-liner website the Horiz. resistance should at least 1.5 ohms. I don't trust this meter I have now to be accurate within such a small range.
Thx for the input,

A guy I know has a nanao with the same low horizontal ohms--according to victor (from 8-liners) this means that the two windings for the horizontal on the yoke are wired in parallel and not series like a typical arcade setup and therefore will not work unless you somehow turn your parallel wired windings into serial connections. I have no idea what this means, whether its true or not and if so how you would go about doing that. if you do find out please post back as this sounds interesting--hacking a yoke!
