Roland PG-800

I finally bought one!
My JX-8P has found its mate! :)

Sorry about the crappy flash reflection

Roland SH-2000

It's not a Roland SH-1000, but almost ;)
I serviced an SH-1000 for a colleague who also had an SH-2000 that he was willing to sell.
His SH-1000 needed the keyboard contacts cleaned, so I took care of that and got the SH-2000 for a good price as "payment" :)

Roland CR-78 non-rechargeable Lithum battery replacement mod

Replacing NiCad with Li.

So, I was servicing a CR-78 for a friend and the old leaking battery had already been removed when I received the unit. After I was done with replacing all the damaged components I was going to put a non-rechargeable battery in there. It's probably possible to replace the NiCad with a NiMH battery, but they recharge slower than the NiCad (so you need to keep your machine running longer and more often to keep it charged) and I'm not sure exactly how they work when they reach their full charge.
As I'm not an expert in rechargeable batteries, I decided that the safest option was to use a non-rechargeable Lithium battery.

I think I'm in over my head...

So, someone was selling an SH-1000 in pieces for a small amount of money.
He said it was in pieces, some switches were missing, and showed some pictures of it.
I thought "How bad can it be? I'll take it."

Oh shit...

Repairing a Synare Sensor

Picture grabbed from video ;)

I was asked to take a look at this strange thing and see if I could repair it.
Supposedly it made fun noises once upon a time, but not anymore. I had never heard of it before and I couldn't really find any schematics, but I decided to look at it anyway.
(I actually fixed this back in Decemeber 2012, but I've been too lazy to post about it until now ;) )
