Zenith G2952 "St Regis" porthole restoration

Thanks. I missed the button switch.

Yes, the 16DP4 fits. They are the same size and deflection angle. 16DP4 is a recommended replacement with the 16EP4.
Room isn't the real challenge though.
The HV metal bar on ceramic insulators needs to be removed and replaced with something that can support the glass CRT at the right height so everything lines up.
I suppose something could be fabricated from wood. Then you'd need to rig up a strap the hold it down.

That aside, I suspect the 16DP4 is even harder to find than a 16EP4.

I bought an NOS Rauland 16EP4 off the 'bay years ago, and was shocked what a poor quality tube is was, physically & electrically. The faceplate had a very significant warp to it, good getter flash, but the tube tested completely dead. Original box, warranty card, the works. Shocked that Rauland would even put their name on that POS.

Sounds more like a bait and switch by the eBay seller. I could be wrong but...

This was back in 2008, when older tubes would pop up more frequently.
Seller auctioned a warehouse inventory of tubes. I got the 16EP4, also a 12UP4, 16GP4, and a 19AP4, all NOS in original cartons with paperwork.
