Questions about 19AP4
1. Can I use a 10BP4 as a test CRT, instead of the 19AP4, on a Zenith porthole chassis? The pinout appears the same. I know I would need to elevate and stabilize the 10" if I want to use the 19ap4's yoke and ion trap. I don't expect a great picture, I just want to validate a raster and deflection.

When using the 19AP4 toward the (hopefully) final stages of circuit restoration, is the method of discharging the CRT to ground the metal flange? I wish to avoid getting zapped in case I bump or handle the CRT after use.
