Hi SDIY folks.

I am rebuilding the Universal Active Filter Module designed back in 1973.

I am looking for a Data Sheet on the SG3821 Transistor array.

It has been a long time singe I used this part and if anyone has a better
replacement suggestion I would be interested in your comments.

I was looking at the CA3046 and CA3086 devices and these type of parts.

We used them at Oberheim for the SEM1-A for Osc. 1 & 2 designs.

I just have not been able to get a data sheet on the SG3821. It would be
nice to keep the same part in the design but I am afraid it may be hard to
find these days.

Regards,

Terry
