This was a sorry looking set of separates lurking in a builders skip.\u00a0 Missing parts, dents, scratches and broken plastic aplenty.<\/p>\r\n

\"Skip
Skip Salvage<\/figcaption><\/figure>\r\n

It’s always worth a look, so I recovered a very sorry Technics SL PS670D CD Player and RS-BX501 cassette deck. Two Sony TA FE370 amplifiers completed the haul.<\/p>\r\n

Nothing here that’s going to be repairable. This haul is all about recovering potential spare parts to fix future finds.<\/p>\r\n

\"knobs
knobs and screws<\/figcaption><\/figure>\r\n

Control knobs and assembly screws are always worth retrieving. Such parts are often missing from car boot finds, the correct replacement knob can make all the difference.<\/p>\r\n

\"Technics

The cassette deck yielded a decent auto reverse cassette mechanism. Thought damaged beyond repair the motors, capstans and maybe drive belts and hubs could all find future use.<\/p>\r\n

\"Technics
Technics CD Transport<\/figcaption><\/figure>\r\n

The CD player provided a transport mechanism, including useful gears, motor and laser assembly.<\/p>\r\n

\"Headphone
Headphone amplifier board<\/figcaption><\/figure>\r\n

A surprise find in the CD player was this amplifier board. A peruse of the service manual for the similar SL-PS7 model confirmed that this is in fact a self contained headphone amplifier. Just add a split power supply and maybe an op-amp swap to convert this into a self contained unit. A project for later.<\/p>\r\n

\"Motorised
Motorised Alps volume controls<\/figcaption><\/figure>\r\n

The real treasure in this haul is the motorised volume control. Two of them. Conveniently mounted on their own circuit boards, these were retrieved from the two amplifiers.\u00a0 While I am generally happy with manual control of my vintage HiFi system, remote volume would be good. There is every chance that one of these good quality Alps units will be mounted in it’s own case to provide that facility.<\/p>\r\n

\"Scrap

The rest of these units are only for scrap. That sort of damage just won’t polish out.<\/p>\r\n
