While the 21yp4 is electrostatic the other 21zp4 is magnetic so is there another way to focus this 21zp4 without the focus magnet setup from the factory. The sams shows hv is 10.2kv for the 21zp4 but if anyone has a sams for the cbs Columbia with the 21yp4 electrostatic tube maybe the hv is the same or different I maybe chasing something for nothing if both tubes are listed at 10.2kv. I already tried setting the hv to 10.2kv but it’s clearly not enough because the screen pulls in typical not enough hv.
