Re: Litte Phatty 3.2 cumulative?

Makes sense since it clears the flash memory before uploading the new one, I guess the only reason to go to 3 before 3.1 or 3.2 is to update the firmware installer /boot loader on the phatty.

Litte Phatty 3.2 cumulative?

Hello -- can I go directly from updating from 2 to 3, then to 3.2 or do I need to install 3.1 on the way?

Thanks!

-- Richard. (Sub 37, Little Phatty, Multimoog)

Re: Sub 37 Gap in case

By the way, Moog is correct it can be adjusted out -- you don't need to take the side panel off just loosen the top center bolt slightly on the 'tight' side, and tighten the equivalent bolt on the other side and it will pull the panel to even out that gap -- then you definitely wont notice it. The p...

Hmm -- pretty soon we'll have accounted for all the multis still in existence in this thread.

BTW what is it with all these people with TWO multis? I thought ONE was pretty cool. Do I need to find another one?

fixed

Bought volatage/capacitance meter. Downloaded service manual. Tested all voltages -- surprisingly, correct. Removed, cleaned, lubricated and reconnected all connectors (there are at least 14). Blew out all the accumulated dust. Seems to have fixed it! So thankfully no need to search for a dead capac...

This is the same though on A and B, does that suggest something further down the line?

Great. I have a mate who knows general electronics, and I have the ciurcuit diagram, so I'll ask him how to check the capacitors and post any joy here. I bet it's a simple fix once you know how.

Doesn;t happen when absolutely cold!

New information! When I fired it up I notice that for a few minutes it sounds fine -- this happens after a minute or two as it warms up. Must be a clue in there for what's wrong. Atfirst, I though a quick clean of the busbar mght indeed have imprved it, but if I hold a note when it's cold, it gradua...

that's the sound

that sounds like exactly the problem. I'm sure the bus bar does need a clean, but since this sound happens in 'drone' mode I assumed not related to dirty contacts. I'll clean it up though and see. I'm finding it impossible to find anyone in Seattle to look at this thing, so if you find any likely cu...

Multimoog double oscillation/harmonic problem

Switched on my beloved multi today and thought it was simply out of tune. However it seems that when I select either osc a or b separately, there's some sort of harmonic being generated. E.g. at F the oscilator sounds OK, but f# or b and beats begin and get more horrible the further from F I get. SO...
