Pioneer SX-450

Vintage 1970’s Tuner/Amp

In excellent condition, this classic 1970’s ‘Made in Japan’ receiver is in full and perfect working order. Smooth, sweet, crackle-free and with all illumination bulbs working. Picture 5 was taken while just using a length of speaker wire as an improvised aerial.

Physical condition is really excellent but some of the veneer on the side-panels looks a bit skanky.

This comes in its original carton and with mains cable. The internal moulded styrene is missing from the carton, so we have packed it in generous layers of bubble-wrap, which will probably do a better protection job. The user manual is a print-out copy from the excellent website. Click here for further info and specifications.

The last picture is from the 1978 Hi-Fi Year Book.
