I noticed the second anode on that 560 tripler is way to short, perhaps that's the reason for the different number?

for the 121-831 HOT, hell its been how many years ?? Caps still are 22-5001. Tripler subs to ECG526A or NTE526A. The following also sub to same 212-141, -01, -02, -03, -04, & -05 The other tripler goes to a newer set with in line guns. It wont help you. 73 Zeno

Thanks for the info!
I have this Tripler already, bought it to replace the Tube Tripler in a Philco Projection set but never got around to that yet. It has the number TCG 523 which I would assume is the same as an ECG 523, I was pretty sure the one in the set uses more than 4 connections but perhaps I was wrong, I need to pull it back apart and check.

Just took a look and my old Tripler has 4 connections, the one in the picture had 5 so maybe that's what confused me.
Do you think this 523 would work?

Well I went ahead and wired in the 523, it works, that is it makes HV and doesn't explode but I'm concerned about how much HV.
Not wanting to damage the CRT I did the the power up with the 2nd anode hooked to my HV probe, but not connected to the CRT, it has 36kv ! Seems a tad high for a 17" set, or even a 25" set. Of course there's no load on it other than the probe so maybe it's OK, or maybe I have a bad safety cap? I think I will replace the Safety caps before going any further.

36k is too much.is there a high voltage control?26k would be more like it.shouldnt be the tripler.look for safety cap problems also

Sounds like one or more of those safety caps has already opened and I wouldn't operate the set again with the CRT connected until the HV problem is fixed.

I'm using a 523 Tripler right now because that's what I had on hand, I don't know the specs on it, it could be a quadrupler for all I know.
Anyone have the specs for a 523?

Manual calls for 27.5 KV max. on the 17" (30kv on 19")
Measure it with no brightness. Wrong tripler and/ or open caps. Each cap that opens gives apx +2kv. They may be causing the width problem also. There is NO HV adjust or HV shutdown in this set. 73 Zeno

I don't have any .0018 1600 volt caps handy, I do have some .001@10,000 volt ceramics, think they would do for a test? I could parallel a couple of them to get closer to .0018

the vert module fails due to them it can cut the neck off the CRT. Some things you dont screw with, this is one of them......... BTW if there are any old shops around check with them for parts. They would LOVE to get rid of them. 73 Zeno

I got this from George over at Talon. Attached is the cross for your tripler - it's a kit, and I dunno if they carry it.
I've got exactly ONE NOS 22-5001 left - you need more. Maybe a collective, some from here, some from there...... Cheers,
