The manual you sent me was excellent. It included clear, readable diagrams and a usable parts list. I would surely use your service again. Thanks

Payments were processed quickly and items were exactly as described. I will use owner-manuals.com in the future for any other manual needs.

The Technics manual was very clear and I was able to solve my technical problems.
I did not think that anyone kept these manuals and was pleasantly surprised to find them on the Internet and at an affordable price.
I would recommend Owner Manuals as a first source of technical products for ‘dated’ equipment manuals.

The content of the manual was not found on the Internet and was a hard find. I check the net for 5 hours until I came across this web-site. When I did find the book it Auto loaded into my IPAD PDF shelf for books for review at anytime. Overall I am satisfied with the book and it answered all my questions. This repair book is obsolete because the product I bout it for is pretty old. Thanks for the help with the download and even having the manual. Thanks 73's K5HRD

Excellent manual including schematics. The service was great and the manual helped complete the job.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer: 1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. 2. Check the interboard wiring to ensure that no wires are �pinched� or contact high-wattage resistors. 3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators. 4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 5. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. 6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer. 7. Check the connector shell, metal trim, �metallized� knobs, screws, and all other exposed metal parts for AC Leakage. Check leakage as described right. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT540A. Follow the manufacturers� instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The �limit� indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOMs that are suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)
