Ducksan type 20 and Samsung 3708b22 hellllp
« on: January 14, 2021, 11:25:19 pm »
Hi all,
Totally new to arcade building but I understand most things but im clueless with CRT screens. I acquired a cocktail table that im in the process or restoring for my own personal gratification as it takes me back to the 1980's.

I need help as I have a ducksan type 20 main board and no crt tube so I brought another screen and mainboard  but I think the flyback is screaming as my ears hurt. The picture is ok even if slightly off cantered and I can't seem to shift it. I was wondering could I use this ducksan type 20 on a Samsung 3708b22 tube on it. Or could I somehow fix this high pitch frequency. Ill include pictures of items, if I can figure out how.
