This little synth is a great one ! It features a really powerful and good sounding oscillator and some very unique modulation possibilities that makes it sound like a big one :o)
This unit is still old and it seems so that this particular one hasn't seen a cleaning in his whole lifetime. There is so much dirt, dust and other oddities that it takes a while to bring it's beauty back to the sun ... take a look at the photos before cleaning.
Photos after cleaning ... The Keybed needs a lot of cleaning and adjustement work too, because it was in a incredible bad state delivering only rare triggers and floating keyvoltages.
A little modification was neccessary to fix a problem with the keyboard trigger pulse. But now it works fine again and is ready for the next 50 years ;o)
