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 the PITCH DIAL BOARD, also referred to in the Service Manual as PY51 which the large Black weighted user knob
Perhaps you need a different part for your PMD340 ... To see the other items I have from our PMD340, please take a look HERE
MARANTZ - CD Player PITCH DIAL ASSEMBLY ONLY
General Information PMD340
Made in Japan
Rack case construction
Single CD unit
Supports standard CD-DA discs but ALSO CD-TEXT (extremely useful for production house produced CD's which may have special information in this area)
Large easy to read Orange backlit display
Pitch change/bend user control
Analog audio outputs (Balanced & Unbalanced)
Digital outputs (SPDIF)
Error correction method: Cross-interleave Read Solomon code (CIRC)
16 bit linear quantization
Built in test modes (explained in the Service manual)
Wired remote control ports
Now to the specific information about this PMD340 Module, the PITCH DIAL BOARD
Part # WA371K104-0 PY51
Sitting to the far right of the PMD340 is a very nice user jog control used for pitch changing.
Perhaps you have a PMD340 with a dodgy pot or more likely, someone has pulled off the large Black weighted knob
No active components on the PCB, just the pot which is another completely sealed AMPS
Black plastic 55.75mm diameter jog wheel/knob is weighted from the rear
Completely unmarked knob
No mounting hardware supplied, this slides/click fits into position behind the front panel - there are no screws used.
PCB DIMENSIONS:
30mm x 24.75mm (very small PCB)
TESTING:
Fully functioning PMD340 until the laser assembly failed, now that the complete CD drive assembly has been removed the 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! The advertisement for the Display module shows this pitch control having been used, indicated on the LCD screen - that photograph was taken immediately prior to the equipment being dismantled.
This PCB has been carefully removed from the equipment and the board is now placed in a sealed clear plastic packaging, awaiting it's opportunity to breathe new life into another PMD340!
