Diode Question & Linearity Coil Question for Wells Gardner 19k7635
1st question, The chassis im working on is a WG 19K7635 medium resolution.. Im just recapping it and noticed the diode at what looks like D18 (probably D16) is completely missing. The legs are still soldered in place. Thinking that this isn't right I checked the parts breakdown in the manual and its shows whats suppose to be there at that position is a "Switching diode" but it doesn't give a value or part number.. What is the value I should put there and do these need to be put in polarity correct ? My eyes are seeing as position D18 but the part number break down doesn't mention a position D18 so I think its D16. Can someone verify that for me ?
2nd question, Same chassis as above, the linearity coil at position L2 has a part number on the coil itself as 9A2813-006. I cannot find a this coil anywhere. Is there a suitable replacement for it ? Or I see Chad at the arcadecup has something close to this with a part number of 009A2813-016 Linearity coil and specifically states its used for the P447 chassis. Can I use that one in its place ? Or is that a upgrade number ? Thanks for any help
