Potential Project: Marantz 9300 powers up, no sound.
I found this on CL, might consider picking it up as it has pre-outs for a 7 channel amp at 105 wpc. which I could use. It's a 2002 vintage with no HDMI, so the pre/pro in it doesn't actually interest me. It comes with the remote.
Thing is, it powers up, no sound.
I found a service bulletin when I was getting the service manual. It says the incorrect main relay was used, should be the 24volt instead of the 12 volt. The correct one is the Omron LY20240490 or G5PA-28. Digikey doesn't have it if I searched correctly. Mouser appears to have it:

But I'm not sure it is the right one. I don't understand the reference to Lot Number on the Service Bulletin. I've attached the .pdf of the service bulletin so perhaps someone could help verify this.
I don't expect Marantz to blatantly say they all do this, but it seems to me that reading between the lines, this could well be the issue. The part where Marantz says: "There is problem in normal useage" seems a little fishy. Don't have the unit to examine to know if this was already replaced in a later run and the issue is something else.
I'm guessing that replacing an inexpensive part is all that is needed, but the seller is looking for $115 for a nearly 15 year old dead unit because it was $3K new in the beginning of the HT era. I think it should go for like $25-50 considering it's age and it's dead.
Could someone please let me know if I have correctly matched the right part from the service bulletin?
Also - this is a risk. If the seller would come down about 50% I am considering taking the plunge. The part would be around $4 plus shipping. The 9300 has the remote, so that could be eBayed to defer costs if this ends up a pig in a poke.
Opinions on this would be welcome. Would you pull the trigger on this?
Thanks for reading and being my "Guardian Tree" on this. (FYI, it's a tree that commands respect and honor and holds the energy for protection and safety).
