First off I would get a transistor checker at this point.
Parts Express carrys one in a kit form(#320-074) for 29 bucks that would take you all of two hours to build.
The best transistor to use in replacement of the greatlty used SE4002 in Kustoms is the NTE199 or a equivilent, as even a NTE123AP does not have the currect gain of a NTE199 and this may be a problem in some circuits like a reverb driver where alot of current is needed.
A 123AP transistor on avaerage has less than 1/3 the gain of a 199!
Caps that do not have a band or line on one end, or a positive and negitive sign are of the non-electroylitic type and can be install in any postion.
