1970s Zenith Console - Troubleshooting

[BeamT]

From Zeno the Zenith 212-139 crosses to a 800-791 in the Zenith Replacement line of triplers. I can see the same information. Also crosses to a NTE/ECG 521 if you are willing to stray to a non-Zenith part. In both the 800-791 and the NTE/ECG 521 there is a focus tap that is unused in this application, so you clip the lead and cover it over with silicone.

From everything I can find the original 212-139 was a 6 step tripler, rated at 30KV max, no focus tap. Sams indicates the Focus Divider is 200meg tapped at 40 meg. It appears to me the NTE/ECG 530, Zenith 977-9530, is close. They are also 6 step triplers, rated at 30KV max, with an internal divider, 240meg tapped at 40meg. Sams indicates we should see 25KV at the CRT, and there is no adjustment.

I haven't found any documentation/information this was a recommended replacement for both the tripler and the divider, but I know this was done back in the day.

It would be nice to hear from anyone that has gone down this path. I asked the same question in my thread about a single replacement for both.

Hope this helps, good luck with your set.
