Working on an Amplifone PCB set. Totally re-worked both boards. Deflection board running perfect in my SW cockpit (so with my own HV board with Cinelabs HVT).
Just tried the other HV PCB (which has a Wintron HVT) and it works great except for one thing. It's blooming.
Now, as far as I understand the word blooming means that the picture size changes in total (so both H-size and V-size at the same time). If that's the wrong word then it is doing what I described and it happens whenever there is a lot of current demanded, so when I am hit by shots or destroying the deathstar.
I checked with my HV meter and the HV was kinda low, so I upped it to 19,5 kV but it's still doing the same. I noticed that the HV dips at the moments the shots hit or the deathstar blows....
I changed back my own HV board and I have noticed the same effect on that one but too a MUCH less extend. The HV seems to dip much less at those moments.
Now, can it be the Wintron being a worse HVT than the Cinelabs not being able to "keep up" with the power demands ? Or is there anything else to check ?
