Re: Replacing a B/W vector tube

Thanks for all the great info !

I succeeded in replacing the 19VARP4 with an A50-120W tube from a 1968 (!) Philips TV.

Here's the story and pics: http://www.dragonslairfans.com/smfor/index.php?topic=3209.210

Looking back it was a piece of cake. The only step I miss in Arcadius' lost is refueling the yoke with some hot glue.

John: the G05's don't come with any centering magnets so I don't use them. They were on the TV though. I think the picture is very nice now. I onlyhave to do a final check with the diamonds screen on my LL.

Thanks to all who replied and to Chris for "forwarding" it to the list.... :)

I already bought one TV with this tube but it still has to come over from Germany, and I'm currently hunting another one her in Holland. This size is pretty hard to find, you see much more very small (portable) or very large BW TS on offer.
