Greetings,
HI Gabe, sorry for the late reply.
You'll need to use bi-polar caps where indicated on the prints. These act
as coupling caps and must therefore be able to pass ac (bi-directional
current flow). The only other way to do it would be back to back polarized,
but then you'd need to add a bias voltage at the junction. Way to much
hassle and in many cases there wouldn't be enough space. You can use the
polarized caps for the power supply de-coupling applications at each IC chip.
I've used Panasonic (good quality, inexpensive and small size) caps for
both bi-polar and polarized. I can get the part #s next time I'm at the
shop if that would help. Sorry, but I have no ideas on EU suppliers.
Good luck!
Regards, Jim

Hello everybody.
My buddies at the studio are willing to recap their Series II.
I inspected the channel board and double checked with the schematics:
there are sixteen 10uF/25V bipolar caps on the channel circuit plus four
2,2uF/50V and the Aux little board.
Before I entered the game, they went ahead and bought the caps but they
got all polarized caps...
Is there a possibility for a polarized to work instead of a bipolar? (this
tells you I am not really an expert but I can do the job!)
Speaking of bipolars, from where we live here in Italy, it looks like the
only option is Nichicon MUSE ES series.
I also looked at Elna RBS Silmic II series but they are out of reasonable
reach.
What do you think?
Anyone in Europe that could point to a resource for finding those?
I could only find some 10uF/50V here in Italy and 150 10uF/25V in UK.
The board has 28 channels so that's 450 pieces of the 10uF.
Thanks a lot for any help.
Gabe
