Hi guys!
I have WG 19k4915 (med res) and i want find tube for use it...manual show M48AAW00X tube, but i have other tube A48ACB24X (H: 1.7ohm - V: 9.1ohm)
Someone know the yoke value of horizontal-vertical res in M48AAW00X tube?


Thanks!

the other tube A48ACB24X you have will work.
but you will need to swap the yokes.

the med res yoke is different than a standard res yoke.

Hi, thanks for your reply!

Tube A48ACB24X have med res yoke, before there was a chassis med res 19k7635, i want know if i can use WG4915 on this tube...

Thanks!
 
yes BUT YOU HAVE TO SWAP THE YOKES.

the 4900 and K7000 med res yoke ARE NOT THE SAME.

the tube is fine and will work.

Hi, thanks...

I never did change yoke, maybe better to try a tube ready to install 19k4915...
Which value must have the yoke to install 19k4915?
Thanks!

you will not find one.

they are chassis specific.

you will have to swap the yoke as it is mated to the chassis.

Ok...thanks for your info

There are difference between chassis 19k7915 and 19k7635?
I have see both in the same tube A48ACB24X...

between those i don't think so you will have to measure the yokes you have to be sure.

but between the two in your first post yes they are.

a K7xxx -- has a low impedence yoke.

and is different from a

WG49xx -- has a high impedance yoke.

Horizontal is about 3.6, I think.

Here's the Vertical:

Thanks modessitt ;)

Yoke for wg 19k4915 are easy to find? What would be the cost?

Nope. I tried a while back to buy some medium-res yokes (of all types and that one in particular) for the purpose of repairing med-res chassis for people, and I couldn't find one...
