These are the typical resistance values between pins for the K7191 HOT (2SD1398) and Regulator (STR30130). This may not tell you if the chip is going to operate properly but you will be able to tell if its blown or not.
Taken as label side up with the digital ohm meter set to "diode". The first value indicates where to position the black lead(-).
2SD1398
1 to 2 open

Slight variations are ok.
Ken Layton:
Those readings only apply if you are using a digital (electronic) multimeter and only if it has a "diode test" function. Readings are much different if you use a conventional analog (meter & pointer) style multimeter.

Click above for manuals for select sega games. You can also contact their customer support people and find out if they have the manul for a game otherwise unlisted. (compliments of Ken layton)

I can't believe I have never been to this site before but nonetheless, if you want a great cross-referencing site go here:
http://nte01.nteinc.com/nte/NTExRefSemiProd.nsf/$$Search
type in your part number , for instance the K7000 HOT is a 2SD1398
and you will get the more common nte part number for it (nte2302)
please keep the "i knew that--were you living under a rock?" statements to a minimum :-[ ;D

Tube readings--you can get donor tubes from tv's and match them to the appropriate chassis (from ebay, your workbench or wherever)
