Quoted from Chosen_S:Hey all,
I have 2 issues I need some help with on Farfalla please.
1. I’m having sound issues. The speech at the end of sound test works, there’s only one sound effect that works (the rollover lane at the top of the playfield). No other sound effects work, if at all they are very momentary. I replaced the capacitors on the sound board, no change other than it took the buzz out of the speakers. I also reflowed the connector pins and the pot pins on the board.
2. I’ve also got the lower pop bumper frying it’s transistor... I’m going to replace the coil which seems burnt and crusty with the Bally/Williams equivalent. I’ll replace the transistor, resistor, and coil and diode and try again, unless anyone has a suggestion of anything else I need to do.
Thank you guys
Marco snd pinball heaven have some zaccaria coils.
I bought a few recently and they work very good.
