Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!
Very good quality scan of the document. I am very pleased with what I got.

DESCRIPTION OF SCHEMATIC DIAGRAM
1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE REPLACING PARTS. 2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING.
1. The unit of resistance "ohm" is omitted. (K = 1000 ohms, M = Mega ohm). 2. All resistors are 1/8 watt, unless otherwise noted. 3. All capacitors are ÂµF, unless otherwise noted. (P = ÂµÂµF).
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH " Ã¥ " ( ) ARE IMPOTANT FOR MAINTAINING THE SAFETY OF THE SET. BE SURE TO REPLACE THESE PARTS WITH SPECIFIED ONES FOR MAINTAINING THE SAFETY AND PERFORMANCE OF THE SET.
VOLTAGE MEASUREMENT CONDITIONS:
1. Voltages in parenthesis measured with no signal. 2. Voltages without parenthesis measured with 3mV B & W or Colour signal. 3. All the voltages in each point are measured with VTVM.
THE AREA ENCLOSED BY THIS LINE ( ââ - ââ ) IS DIRECTLY CONNECTED WITH AC MAINS VOLTAGE. WHEN SERVICING THE AREA, CONNECT AN ISOLATING TRANSFORMER BETWEEN TV RECEIVER AND AC LINE TO ELIMINATE HAZARD OF ELECTRIC SHOCK.
WAVEFORM MEASUREMENT CONDITIONS:
1. The colour bar generator signal of 1.0V peak applied at pin (24) of IC201. 2. Approximately 4V AGC bias .
