Bonjour !
I am Frenchand happy to join this group of Polysix owner. My old Polysix bought back in1983 has been sleeping in the attic since 1990, until I have returned back now tomy first love. Unfortunately I have discovered the battery leakage problem !
So I did the standard procedure (like many)
Spend a lot of time checking the lines on KLM-367 with plenty of leds on at start up..
Browse internet for hours (discover service manual, old crown, etc)…, change IC30 & 31 … recheck continuity, still few leds on..
Recheck again, change all set ofpanel switches (vintage planet)..4 leds on... Bank B not working...
Check lines again, to get finally only leds A1on start up. Great !
Unfortunately soundis not OK.
Tune seems OK,6 voices are OK, voltages from power board are OK (15V, 5V -5V and -15V) all potsand switches seem to work except the 4x EG and 4x VCF pots which are notactive!
I think atthis stage it is useless to do the calibration procedure. Is there some indications,checking to start with to define if it is still a line/continuity problem or if electronic parts (IC, diode..) should be changed.
Thanks inadvance for your help
Phil
