[sdiy] tired old question: Juno 106

[CCartCat at aol.com]

I googled and found some info (including a post by Michael Bacich) but 
thought I post here for any add'l info:

Juno 106 is dropping the 2nd voice--checked it in test mode.   Never opened 
the Juno and just kinda wanted some clue before I did.

The 2nd voice drops out intermittantly, works sometimes, coming thru sputter 
and static as if thru a bad connection.   Some general noise in the 2nd voice 
when activated, whether the tone comes thru or not.   Sometimes cranking the 
resonance control to about 75% to 100% will cause the tone to come thru.   

Is it definitely a malfunctioning chip or perhaps some shotty connection that 
even this mere lurker can correct?   

FWIW:   Also put filter in self oscilation and turned off the DCOs:   not all 
voices are at the same pitch in self osc. (OK, that I can live with--just 
saying for the sake of diagnostics); voice 2 is dead quiet and 4 has maybe the 
faintest sound coming thru if you listen really carefully.

Have read in my Google travels that certain chip lots (41C and 42B) were bad. 
  But have had this Juno for years generally working (at least to my 
standards).

Were this voice 6 I might take a Brian Eno attitude:   rename it Juno 105 and 
move on.   But voice 2 is a diff story.
 
Thanks for any info/suggestion/heads up,
Kevin Seward
