My Analog Board Replacement Parts List, mostly capacitors (note there are two sheets):

On your Google Doc you have this Digi-Key Part Number: PF2395-ND for C1 which should be a 3.9µF(J) NP HF 250V 105°C, right? But the specs for PF2395-ND says "Operating Temperature: -25°C ~ 85°C". Is this ok? OR should i get P13751-ND with Operating Temperature:-40°C ~ 105°C instead?

Since you didn't mention any Digi-Key P/N for CR20, I found MBR1045GOS-ND which matches the specs you specified. Is this the right one?

For C33 and C37 I found two. Should I get WYO472MCMCF0KR(element14) or DE2E3KH472MA3B(digikey).

For CR15 and CR19, you listed 1N4735ADO41MSCT-ND but it's not available on Digi-Key. Can I get 1N4735AFSCT-ND instead?

Also no stock for P5928-ND(EEU-EB2E101). How about EEUEE2E101?

Which ones are these on the board?

805-0563 upper RFI shield

805-0577 lower RFI shield

22 AWG J4-J7 harness

HF is High Frequency. All caps that are spec'd for HF will mention such on their datasheets. If a cap doesn't say it's HF, then it's a LF (low frequency) part. You need HF wherever I wrote HF in my list.

Usage of the diode is easy. Note the datasheet:

Note that Pin 1 = Pin 4 electrically. You therefore can just cut off pin 1 and connect pin 3 to the PCB thru-hole, then screw-in the top section of the part to the heatsink on the analog board, as shown in my photos here:

Ok thanks I got it.
