schematic of HD-1530 DTMF Decoder - Need LS7225 IC

[Alex [Temple-Heath List]]

Thanks to the schematic I determined that I need to replace the 
443-1290 IC, which crosses to LS7225. Does anyone by any chance have 
a spare they would consider selling/trading? Not sure Heath used this 
part in any other gear besides the HD-1530.

More info on the LS7225 (and LS7226):

BTW, no luck with the usual sources (Mouser, Digiket, etc). Not much 
interest in buying from the "obsolete parts" overpriced "RFQ" sellers 
out there.

Thanks.
