Checking Vertical Output Transformers??

[Tubejunke]

I am still battling the 1958 Zenith Space Command (18C24Q) that I have posted many times on being stumped on a recap that produced no improvement in the set with little vertical sweep and hum for sound.

My latest efforts have been disconnecting the transformer leads and yoke leads in order to take some resistance readings.

On the transformer I get 317 and 326 ohms across the two sections and 9.6 ohms between the two. Infinity to chassis. Does anything sound off?

With the yoke its hard to know what to do. Inside the back cover are several resistors and a capacitor. Best I can tell two 560 ohm resistors work in the vertical winding portion. Neither of those 10% resistors was higher than 609 ohms. I disconnected both resistors to attempt getting winding measurments. I came up with 22 ohms between three different points. From a similar set schematic that I have 22 ohms is a good reading but shouldnt I get that reading at four sepearate test points if reading the resistance of two seperate windings? Does that make sense?

Anyhow that's where I am at with this great looking DISASTER..

This set is in such great shape it is unbelievable. It looks as if it was only ever used a couple of years with nearly all Zenith stock tubes and a super healthy crt. Someday I feel like whatever crazy thing is keeping this set from working will surface and the set will be a good one for normal use with the large 24" crt and remote control. Not quite run of the mill.

If anybody has a remote for one of these I need it.
