Default B&O ICE200ASC


has anyone built a set of these?

I'm helping a friend trying to do some repair work on a rawson build.

it has 2 of the 200ASC modules, 2 of some driver board (input signal goes to a volume pot into these driver boards then goes into the sig. input of the 200asc).

was wondering where he got the circuit for the driver boards. the psu looks like 2 seperate supplys for each ice module.

attached are pics of the main psu and the driver boards. it's missing the transformer, looks like it needs a 60V x2 pcb mount trafo. I have no idea
where to get that. any ideas where these are from?

thanks for any help.

the ASC does not need an external power supply, it is build in.
my guess is that the boards in the pictures connect to the power-OUT of the ASC to provide power to the driverboards. they look like some home made job, not like B&O stuff.
I do have all the documentation for the ASC and the AC modules so I can help you with those
