Does anyone have or know of a crt substitition guide that still exists? I know there is an electronic distributor who has a lot of crt's in stock but the numbers are somewhat different from the old numbers, for instance I know that in it's final stages most 21" roundies were converted to a 19" part number by some manufacturers.


If you have that infomation maybe we all could get some good stuff out of it!

The Sams tube substitution handbooks have a CRT section. The latest one I have is Volume 16 and it's last copyright date is 1973, so it's probably going to cover most anything we're concerned with. It shows the 25 to 23V numbers ie. 25XP22 to a 23VALP22 etc but I don't see any 19V round numbers, as you said that was very late and Volume 16 may be a little old to show it.
