...Part #17775201? I have checked with Sony and the original part number was 983126967 and was changed to 177752011. This home theatre system is about 12 years old. It looks and sounds good. It is a component unit that the tape player etc. sets on top of the woofer unless you can get an extensinon cable. Thanks for any help that you can provide since I have a new entertainment center that I would like to use to house the Sony stereo system.
