Lexicon MPX G2

[Systematic Chaos]

We have a saying in Germany: Der Teufel ist ein Eichhörnchen! (The devil is a squirrel)

When EC told me that all of a sudden the G2 would be going through a continuous start-up cycle I instantly knew it was the battery since I had the same last year....
Luckily we did complete Data Dumps in our efforts during the last two days so it's now just a matter of replacing the soldered CR2032 with a socket and a new battery, upload the saved data sets and go for it....

The batteries in the Lex MPX-G2 are nearing their 20th anniversary so anyone having the unit might wanna consider doing the battery replacement.
For the G2, a vertical CR2032 socket/battery holder is needed....

Or like with the MP1, you could just pick up a ready to solder CR2032 (has solder legs attached). Using a socket is more elegant but given how long the batteries last it's probably cheaper and easier just to go with the ready to solder in variety.  They are reasonably common as they are used in many computer main boards etc.

While being at it I deemed it the more "elegant" way (same as MP1 battery mod) to use the socket variant...it's a matter of a few cents more in the end....

Hey SC, I agree a socket is more elegant. However, MP1 mod is flat socket. When I looked for vertical sockets (for MP2) they were quite thick (so not ideal for MP2 space wise) and harder to source here. While looking in the electronics store for a vertical socket I found the ready to go CR2032s (quite cheep) and no vertical sockets to be found. Then my thought was, if I only need to change this every 20 years.... and I can't source a thin enough vertical socket easily...

no space issues as in the end (including the battery) it's the same size as the battery with solder lugs....
Together with a CR2032 it cost me 0.76€

That store is 5 klicks from where I live

Hang on a second!  Let's just back this up. I think everyone is missing the real point here. .. what the hell does "The devil is a squirrel" mean?

Hey SC they look good, can't get them here  :facepalm: all the ones I found were much thicker. So do the lugs line up with the MP2 PCB ?

Spec sheet and measurements (in mm):

According to that it's the same spacing as a CR2032 with solder lugs (vertical mount)

These are not suited for the MP-2.

[rnolan]

Thanks MJMP, why though ? It was hard to see from the pic, I wasn't sure the pins were in the right spot ?

@SC please cancel that request I emailed you.

Cheers R

The pin spacing of the holder is too small.

Well dont know if we said this before but after doing the preset dump, saving it to the computer and uploading SC presets the internal battery of the Lexicon hit the fan and the unit started powering up and then reseting and doing it all over... so today I purshase online the batteries for bothe the Lex and the MP1. In one week they should be here.

I think tomorow will be a busy day!

Hey El, have fun, it's nice to fix things (well I like it  ;) )
