what is this?

NTE still list triplers in their cross reference guide; but, I don't know if any are currently being made. My local parts house has a few NOS ones; but, I don't think they're making any effort to restock them. Heck, I think I'm the only one that has bought a tripler from them in years. Also, I can't imagine there being much demand for triplers for '70's TV's, outside of the TV collecting community, as most people won't have a 10 year old TV fixed, let alone a 30+ year old set.

Years ago, I had a '79 Philco console that looked almost like that set. It was nothing more than a rebadged Sylvania as GTE owned both the Sylvania and Philco names at the time. My set had a 25V delta gun CRT and a single board chassis that was mounted on a metal frame. I can't remember; but, it seems like the chassis number was something like an E21 or E23 or something like that. I remember similar 19" and 21" models with an inline tube and the 25" consoles used a delta gun tube.
