Zenith A27A11D

Thanks for all the help on my Zenith A27A11D portable that I found on the side of the road. I replaced Q-3401 which was shorted, RX3415 (degausing thermistor), and IC3431 which did not check bad, but I changed it anyway. I'm thinking about putting it back in though. The problem I have now, is the purity, and the color needs to be realigned. Also, the focus is way off. I bet I have a difference in voltages from this NEC Voltage Regulator. I noticed that there are no pots or adjustments on the CRT board, and the only pot I have seen so far, is the horizontal size. I suppose all of the adjustable components have been left off, and fixed components were used in their place to save on production costs. Everyone thinks I'm crazy for trying to repair this old dog, but all of you electronic types out there like me, can surely understand our hobby. Can anybody tell me what resistors to check for the color circuit, and where the focus circuit is on this baby?
