1) Get your cap list here: http://www.juniorsrevenge.com/MonitorCaps.html

2) Radio Shack probably won't carry all the caps you need, nor in all the sizes you need them.

3) 506 refers to the location, not the value. As in C506.

4) Not sure what a 19K49xx has to do with a Tempest, since a raster K4900 will not work in a vector Tempest...

In a tempest cab thats what I meant. Its a jamma game with the questioned monitor.
Thank you for the help and that link, it was great.
 
Looking thru the cap kit list, I noticed there is a K4900 list and a K4906 capkit list.
I have a 19K4953 Wells Garner, which capkit list do I follow? Lists are similar, but differ in a couple places....
List below:




===================
Wells-Gardner K4900
===================

C201 - 1000uf 16v
C205 - 470uf 16v
C301 - 330uf 25v
C303 - 2.2uf 50v
C308 - 2.2uf 50v (may also use a 3.3uf 50v)
C310 - 10uf 100v
C311 - 4.7uf 160v
C313 - 100uf 160v
C315 - 1uf 50v
C351 - 1uf 50v
C352 - 47uf 25v
C354 - 47uf 25v
C505 - 560 uf 200v (Filter Cap)
C506 - 22uf 160v
C507 - 47uf 160v
C701 - 1000uf 25v
C702 - 10uf 100v

There is also a 1uf 50v cap bridged over the top of D306, using the same
holes as the diode. Negative lead matches the banded side of the diode.

The voltage value differences aren't that big of a deal, as the lists were compiled separately, and some have voltage upgrades that aren't actually necessary.

To answer your question about which to use, check the value of C313. If it is 100uf, use the 4900 list. If it is 47uf, use the 4906 list...
