HISTORY:
Sustainability is the name of the game! Anything that can be reused or repurposed creates Ee savings and reduces the poisoning our environment when items are buried in the earth at the local tip needlessly.
Never heard of Ee? It is a concept that creates a measurement of ALL things (not just electronics) that humans have made and the energy used in obtaining the raw material, processing the materials right through to a finished product and even should include the shipping of the item to the distributors/retailers.

So who may want just the input function PCB module for the PIONEER Z-93?
Sometimes disasters happen and the rear RCA connectors become damaged, this board will solve the problem. Some may even use this board as a "component farm", the active devices are listed below.
This is one of the "easy boards" to swap out of an existing Z93 system - unscrew two screws on the rear panel and one on the PCB. Those ribbon cable connections lift off at the Main board end, NOT on this PCB. There is a trick to doing the ribbon cable disconnect/connect procedure ...both of these ribbon cables are connected on the Main board with WHITE connectors (this is very important - the Grey/Connectors are NOT push fit types)
The white connectors are like this, it can be seen that they "clamp" together holding the ribbon cable wires in the process BUT do not try to lift the top section of the connector upwards to release the ribbon cable - it will not work and you risk destroying the connector! It is actually easy to remove the cable (but not so intuitive) - PUSH DOWN on each end at the same time and while this downward pressure is applied, lift up and out the ribbon cable - it will release easily! You really need three hands but a "widely spread" pair of small pliers can help. Use the pliers to apply the light downwards pressure evenly to the connector top section (at each end) and use your other hand to lift up the ribbon cable out of the connector spring contacts. Bingo! you have freed the ribbon cable - insertion is the reverse process.
PIONEER - MIDI Stereo System Component
COMPONENT: Input Function Module
PART # : AWK1174(A)
This is the module which has 4x RCA Phono connectors at the rear, being for DAT IN, DAT OUT, CD IN, PHONO (Turntable) IN
Supplied with the 2x Black interconnection ribbon cables.
Easy to remove the old PCB and refit this board, takes just a few minutes!
COSMETIC CONDITION:
Very nice condition!
CLEAN
NO damage to the board or components
NO damage to the ribbon cables at all and the "push fit" bare wires are undamaged and straight
OBSERVATIONS:
Known to be fully functional as it was removed from our Z93 with the failed twin cassette decks, ALL other functions were working perfectly.
Now what are those active devices?
TOSHIBA TC4052BP IC (Multiplexer/Demultiplexer)
TOSHIBA TC4066BP IC (Quad Bi-lateral Analog Switch)
2x JRC4558DX IC (Dual OP Amp)
2x DTA143ES Transistor (PNP Digital Transistors - built in bias resistors)
DTC143ES Transistor (NPN Digital Transistors - built in bias resistors)
Now packed in ESD material, ready for safe shipping.
