HISTORY:
Sustainability is the name of the game! Anything (that has been tested and still functioning properly) should be repurposed creating saving in wasted Ee and reducing 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.

While the Marantz PMD340 is a good workhorse in the audio production environment, it becomes pretty useless once the CD drive fails and the laser assembly has gone A.W.O.L!
This machine was in use by us for long periods in a studio environment, never missing a beat until the laser needed replacing. Tech's took the laser electronics out to have them replaced and "poof" disappeared, somewhere. So I have this PMD340 which is absolutely fully functional but without a laser - pretty useless.
I no longer am prepared to spend time servicing our equipment (retired and TRYING to have a break from all that) and as a result, this equipment has now become an "organ donor" for other PMD340 owners.
This is ONLY the Infra-red detector board, (remote control receiver sensor) also referred to in the Service Manual as PY41
Perhaps you need a different part for your PMD340 ... To see the other items I have from our PMD340, please take a look HERE

Wired remote control ports
Now to the specific information about this PMD340 Module, the IR DETECTOR BOARD
Part # WA371K
Function is to receive infra-red signals from the remote control and pass them to the main board for processing.
NO permanent interconnections, all signals are routed via connectors on this board.
2x screws (Philips head) support this board behind the front panel, very easy to remove and access/replace the board.
PCB DIMENSIONS:
42mm x 11mm
TESTING:
Fully functioning until the laser assembly failed, now that the complete CD drive assembly has been removed the main PMD340 system still works (in a fashion) with all front controls active such as track selection, pitch bending etc but of course anything that requires signals back from the laser reading do not work! These tests were made with the remote but I no longer have the remote. Once a colleague heard I had one spare, he shot over and bought it!
This PCB has been carefully removed from the equipment and the board has now been placed in a sealed clear plastic packaging, awaiting it's opportunity to breathe new life into another PMD340!
