Exactly what was needed to assess the product - excellent value and great service
 ;
A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.
 ;
Quality scan of the original. All the detail necessary to troubleshoot, repair and adjust the unit. I'm sure I will be downloading more manuals in the future as the need arises.
 ;
Exactly as described, a Service Manual complete with the schematics and PCB layout delivered in a timely manner. Many thanks for the great service.

some of the writing is a bit blur but the part in the schmatic was great and i have fixed the machine thanks
SCHEMATIC DIAGRAM
MODEL : 51HC85/57HC85/65HC15/65HC85
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "X-RAY RADIATION PRECAUTION", "SAFETY PRECAUTION" AND "PRODUCT SAFETY NOTICE" ON THE MANUAL FOR THIS MODEL. CAUTION: The international hazard symbols " " in the schematic diagram and the parts list designate components which have special characteristics important for safety and should be replaced only with types identical to those in the original circuit or specified in the parts list. The mounting position of replacements is to be identical with originals. Before replacing any of these components, read carefully the PRODUCT SAFETY NOTICE on the MANUAL for this model. Do not degrade the safety of the receiver through improper servicing.
NOTE: 1. RESISTOR
2. CAPACITOR
Resistance is shown in ohm [K = 1.000, M = 1.000.000]. All resistors are 1/6W and 5% tolerance carbon resistor, unless otherwise noted as the following marks. 1/2R = Metal or Metal oxide of 1/2 watt 1/2S = Carbon compsistion of 1/2 watt 1RF = Fuse resistor of 1 watt 10W = Cement of 10 watt K = ±10% G = ±2% F = ±1% Unless otherwise noted in schematic, all capacitor values less than 1 are expressed in F, and the values more than 1 in pF. All capacitors are ceramic 50V, unless otherwise noted as the following marks. Electolytic capacitor
Mylar capacitor
3. The parts indicated with " " have special characteristics, and should be replaced with identical parts only. 4. Voltages read with DIGITAL MULTI-METER from point indicated to chassing ground, using a color bar signal with all controls at normal, line voltage at 220 volts. 5. Waveforms are taken receiving color bar signal with enough sensitivity. 6. Voltage reading shown are nominal values and may vary ±20% except H.V.
