PAIA OZ nuisances
2006-04-23 by easterleggs
My Paia Oz has new 4013 chips, socketed, and a new amplifier chip. Before the repair, the lower half or so of the keyboard had fuzzy or intermittent notes. All notes but one are fine now. The low F does not produce any tone now. Is it safe to assume this is a bad cap upstream of the oscillator chips...in other words, something associated with that particular key only? I'd be curious to hear a layman's explanation of the tone-producing pathway from the perspective of a single key on the Oz...anybody wanna take a stab? Also, my volume pot has no effect. The tone pot instead seems to control the volume to some degree. Anyone experienced anything similar? Thanks for any help! --Stephen
