Up for sale here is this Technics SA-200, SA-300, SA-400, SA-500, and SA-600 rear speaker connector and fuseholder panel.  I am pretty sure it will work for all those receivers, but please double-check that yours looks like this one.  This is in great shape with just very light wear.  All of the twist-lock speaker connectors work well.  No fuses or fuse cover are included.  This may work on other Technics receivers and possibly on other receiver brands as well.  Please see my pictures for details.

US shipping and handling is $4, and international is $12.  I accept Paypal.  If you have any questions, please ask.

I have a number of other Technics SA parts, collectibles, Magic cards, and vintage electronics listed--feel free to take a look!
