Just picked up a like-new BK 490 with case and a few adapters. From what I can tell, it comes with adapters 1, 3, 4, 5, 6, 20 and 23. What other adapters do I need to handle 99% of the most common arcade tubes?

bk467 and 490 is very nice. I think its easier with 3 meters.

24 for xy and 31 for some k7000. Not sure what nintendo is (I think its 23)

Most Nintendos are CR23. The 15" color monitors in cocktails are CR25.


Between the CR6 and CR23 you have about 80% of the arcade monitors covered. If you have a color vector with a WG6100 then you may want a CR24. Any "skinny neck" tubes will require a CR31. If you have any Matsushitsa monitors then you'll need a CR30.

good to know. I assume cr6 is for B&W.

Not sure which 15" N* monitor you mean, since there aren't any :confused:
But here's a comprehensive socket breakdown for N* monitors (I own them all :))

19" Sanyo's (DK+) ----- CR23
19" Sharp's (PO/PC10)---CR31
13" Sanyo's (DK) ------- CR33
13" Sanyo's (SD/SF) --- CR25
13" Sanyo's (Atari) ----- CR25
18" Sharp's (Tents) ----- CR31
18" Sanyo's (Table) ----- CR23

Note that the 13" Atari is referred to as 14" in their documentation (lacks audio amp, used in Missile Command and Warlords cocktails) and the 18" monitors are sometimes referred to as 17". For the newbs, that's because the Japs measure glass, we measure viewing area.

All Nintendo documentation I have ever seen refers to the 13" monitors as 15", that is why I called them 15". I realize their actual size, but Nintendo likes to be "different".

When you say 13" versus 15". are you measuring straight across the screen or diagonal from corner to corner? I've always heard screen size is corner to corner

Technically, the nintendo monitors are called either 14", 18", or 20", but in our world they are 13", 17", and 19".

Yes, you determine the screen size by measuring corner to corner diagonally, but in the US the size is the viewable are, while in Japan (and a lot of overseas places) the size is the actual outside dimensions of the tube.

This is why you actually have to check the tube label when doing tube swaps. Some TVs will be listed as a 20" model, but when you check the label you find it is an A48 (19") rather than an A51 (20")...
