INTRODUCTION:
Denon's DP-30L is a great turntable, good entry level, well designed and engineered.
Nice heavy beastie - weighs around 10Kg, good solid platter
Drive drive motor is made to last, one of the largest and best made that I have seen - built like a battleship
The DP-30L features a good solid speed control (feedback loop compared with a reference signal)
Auto lift without using any gears, this works very nicely
No clumsy gear systems around the tonearm which might restrict free movement of the arm - end of record detection is via a photo interrupter system.
From an engineering viewpoint, very sensibly laid out - easy to work on
My DP-30L was one of our turntables in our audio production facilities, sitting alongside Linn Sondek LP12's, Technics SP-10's and others.
This Denon DP-30L did its job well (one of our studios specialised in audio archival work) but it has seen better days cosmetically, the tonearm was accidently destroyed by a clumsy staff member and the turntable body had "graffitti issues" so I am parting out the major parts I think might be useful to someone.
Prior to advertising these various sub-sections, the turntable has been powered up today one more time and I checked the most important aspects - motor noise, speed control, end of record detection and the tonearm lift system. Not only functional checks but voltages and control signals where applicable.
EVERYTHING was functioning exactly as it should.
While dissassembling, sometimes I have had to desolder the connecting wires, I have included photographs which should help with re-assembly or servicing
I can also supply a good service manual for this turntable, in pdf format.
You could build up a complete DP-30L with these sub-systems I am offering, the only parts needed are the heavy white/cream body, metal plate underneath the platter and the black base underneath.
All mounting screws for each sub-section are supplied along with the electronics
Denon Direct Drive Turntable
Model: DP-30L
Part number: 2339023109 2228148
AC Power Transformer, AC filter printed circuit board, Front panel power ON-OFF switch
Fully functional and all components are excellent condition
Complete with all of the mounting hardware, filter board cover etc.
Fully tested when the turntable had its "final spin" - no problems at all, I checked the voltages and they are spot on. This assembly provides 9.5V - 0 - 9.5V (main supply) and 100V (motor) to the main board. Reconnecting is easy as this uses colour coding (Yellow-White-Yellow is the 19V centre tapped and Brown-Brown is the 100V).
Currently set for 240V AC input but other voltage inputs are available should the need arise.
The printed circuit board provides the extensive line filtering and a fuse.
The front panel ON-OFF switch is working fine (push on - push off) and includes the round brown button
Since removal from the turntable, this AC power transformer, PCB and switch are now stored in a sealed plastic bag
