Comes from over here:

http://www.nteinc.com/

From first exploring not being able to locate the chip under "semiconductors", however, a keyword search leads to this subpage:

http://www.nteinc.com/specs/1000to1099/

Others than that, I'm lost here. You may contact them for further information.

Further searching leads to:

http://www.wallcoinc.com/NTE_NTE1022_IC_4_CHANNEL_SQ_DECODER_p/wal7-nte1022.htm

A "NTE NTE1022 IC-4-CHANNEL 'SQ' DECODER" available for $6.98!

But if it's SQ, where is the phase shift network?

From my understanding NTE produces replacement parts for obsolete industrial type ICs. Too bad their homepage doesn't tell for what this replacement is for.

I doubt it being quad, otherwise it should have mentioned the system (QS, SQ, RM, whatever). Maybe a chip for car radio, since most cars have four speakers included? Some kind of pseudo-quad? That would explain the balancing resistors... or not.

It's probably easier to ask those guys at NTE rather than us. There is an email address included.
