How to Replace the Battery in the KORG Polysix with a Battery Holder + Repair Minor Trace Damage!

Please join us while we repair some minor trace damage on the CPU board of this Korg Polysix and install a coin cell battery socket. This Polysix had minor acid damage, but it can often be much worse. This is a very common problem, so we tried to demonstrate a thorough repair. If you do have a damaged board, hopefully this will help you repair it. We don't claim to know it all, we simply record these repairs in an attempt to help others. So, if you have tips, better methods, etc. please help everyone by sharing them in the comments. Thanks for watching and please subscribe!

*If you don't want to take the risk of attempting to repair the CPU board yourself, you can buy a modern clone version here that is very well made here: https://synthronics.de/klm-367a-repla...
