Discussion about the Korg PolySix synthesizer

Hello!
I recently completed one the KLM367 Clones and the MG circuit is not working properly. When I  turn it on the MG speed slowly ramps up to maximum speed and the level is stuck on "10" I did  all the bug fixes to no avail. The arpeggio speed is normal. Also, during the calibration found in the service manual, when you are supposed to make 1 and 8 light up in test mode after switching the tape enable on, I can only get 1 and 5 to light up. 

or  {2 and 5}
or  {3 and 5} 
or  {4 and 5) 

Has anyone else experienced this problem? Thanks! Greg
