In addition, I don't have a CRT tester as of yet, but based on what I have seen so far i believe i have a decently good 15GP22. I was getting a good grayscale out of it and decent brightness for a CRT of its type (no, not like a Chromacolor or Trinitron, but you don't have to squint in a dark room, either). I haven't installed the CRT since doing the IF alignment, so I don't know what kind of improvement I have made with that. I need to get more .1uF capacitors ordered, and need to find a solution for the convergence transformer. I was getting grayscale shift due to leaky bypass capacitors on the G2 grids causing the voltages to change by several volts.
