PM4007A - where to buy a couple

[Sergey Kubushin]

Hi!

Does anybody know where I can buy a couple of Pioneer PM4007A chips? They
are quite exotic in function, Laser Disc AC-3 (Dolby Digital) RF
demodulators. There are ready-made boards with them but they are quite
expensive and they don't physically fit into my application.The complete
demodulator device is not that complex so I'd like to include one into my
own project...

Any information is highly appreciated.
