I dropped the MP1, so it went to rack heaven, but I think that's still sitting in the back of the repair shop for spare parts, so I could probably get those back, if I wanted  ???

Was the MP-1 so badly damaged ?

Hey Max, I've been using the New Sensor re-issue Russian tubes, cost around $25 AUD.  They also do a short plate version, MikeB uses a Boogie SPAX7 and a Mullard short plate in his MP-1.  I like the long plates as they are very "3D" compared to other tubes I've tried.

Ciao Rich!  :wave:
Yes, I agree about long plates. I tested a pair of long plates Groove Tubes 7025 and a pair of long plates Ei ECC83 in my MP-1 with awesome results.
Then I came back to Ruby's JJs, 'cause those have a killer tone.
But one of these days I should give Mullard LPs a try.

So he said, but I'm fairly certain it can be fixed by someone else.  I don't have it in front of me, otherwise I could tell you the error message that popped up.

Will do, MJMP!  I just found out my office is still open on January 18th (Martin Luther King Jr. Day here in the States), so that kind of screws with my plans of picking it up from the shop that day  :facepalm:

I picked up the crapped out MP1, powered it on, it displays "C" and then cycles through the 128 numeric characters, then pops up Err 1, 2, and 3.

Dead battery? Or EPROM read?

I'm guessing EPROM because it powers on and can recall the factory presets, but it won't save anything.

That's dead battery usually, not EPROM. Factory presets are in the EPROM, saved programs are stored in RAM and kept alive by the battery, when the battery dies, the saved programs are lost  :facepalm: So good to back them up with a sysex dump or write them down (irritating but effective).

Dead battery.
It's the RAM (user settings), not the EPROM (factory presets).

It's still cracked open, so I can check to see if the previous owner put an aftermarket battery in there (i.e. solderless).  You're saying if I swap in a new battery, it should go back to normal?

Yes it should in 99% of the cases. Do you have sound?
