Bally MPU Corrosion Repair - question on replacing a 390pf with at 430pf ceramic cap
I'm working on my first Bally MPU for an Evel Knievel. I'm following the guide at pinrepair no problem. There was a bit of typical battery corrosion so I ordered the battery corrosion repair kit from GPE.
As the title states, I'm replacing a ton of corroded parts but there are more than what is in the kit so I picked up the rest locally... essentially any component that has any corrosion at all is getting replaced. Which leads me to 8 ceramic caps on the lower right hand part of the MPU board. The values are 390pf. I typically can get most of my stuff locally and stopped into the distributor today but they did not have this value but suggested I replace it with a 430pf ceramic cap.
Is this a suitable replacement for these caps? 4 of the 8 will need to be replaced (the bank of 4 that are closest to the bottom of the board).
Thanks.
