Hi Tony,
It was really a thrill seeing this today, I took the back off and poked around a bit and was amazed at how 30+ year old memories seemed as fresh as stuff that happened last week!
The date on the CRT is the 48th week of 1968, I thought we got ours in 1970but I could easily be off by a year. (My Mom won it in a Grocery Store Raffle!)
I checked the tubes and found a shorted 4JD6 and (gasp) 6GH8!
The CRT checks good. It has issues with the sync but the pic looks pretty good when it sits still.
There are several Compactrons in this set including the Horiz output which is a 22JG6 where I could swear ours had a 38HE7 in that position, perhaps a revision (or a bad brain cell)
Edited to add this picture.
It's in remarkable shape overall!
