So my lengthy reply disappeared when I hit post grr... lets try this again....
Quoted from TimberOne:I think the pinsound will fix the buzz. If you do LED you likely will need a OCD, I got terrible ghosting w/ led but the ocd fixed it all, looks awesome now.
Ordered, I was looking at those the other day wife gave the nod of approval today lol
Quoted from Schwaggs:My DESW had buzzing with the stock board. Replaced with a Pinsound board and it works perfectly and zero buzzing.
Good to know thanks. It'll be my next upgrade after I fix motors and lamps.
OK so I dug into the ghosting problems. These are NOT leds. Forgive me if this is an obvious fix I'm new to SS machines. I don't know if having a large number of burned out and missing lamps would cause this. Let me know if I should start at the transistors on the board or sockets and diodes.
Force lamp (47 Power scoop left) Ghosts on every row test lit correctly on row 7, does not ghost on any column test. Lit correctly on column 6. On individual lamp test it ghost with everything besides lamps in row 7 and columns 2 and 6.
Shooter lane (Launch 31) ghost on row 1,5,6 lit correct on row 7. Does not ghost on any column test, lit correct on column 4. Individual it ghost with every lamp in column 4.
Only did individual tests with the following
39 drop center ghosts with every lamp in it's column (5)
63 right bump ghost with every lamp in it's column (8)
23 DS tie ghosts with every lamp in it's column besides 17 (not used) and 18
48 scoop right ghosts with 56.

Starting to wonder if my good deal wasn't such a good deal. But we agreed this pin will never leave our house so I'm not too worried about it.
Thanks in advance.
