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 This repair book is obsolete because the product I bout it for is pretty old.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

X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazardous X -R AY R A DIATIO N .To avoid such hazards, the high voltage m ust not exceed the specified lim it. The nominal value of the high voltage of this receiver is 26.5kv(25�), 29.5kv(29�) at max beam current. The high voltage must not, under any circumstances, exceed 29.0kv (25�), 31.5kv(29�). Each tim e a receiver requires servicing, the high voltage should be checked. It is recom m ended the reading of the high voltage recorded as a part of the service records. it is im portant to use an accurate and reliable high voltage m eter. 2. The only source of X-R AY R adiation in this TV receiver is the picture tube. For continuous R AD IATIO N protection, the replacem ent tube m ust be exactly the sam e type tube as specified in the parts list.
SAFETY PRECAUTION
1. P otentials of high voltage are present w hen this receiver is operating. O peration of the receiver outside the cabinet or w ith the back cover rem oved involves a shock hazard from the receiver. 1) S ervicing should not be attem pted by anyone w ho is not thoroughly fam iliar w ith the precautions necessary w hen w orking on highvoltage equipm ent. 2) A lw ays discharge the picture tube to avoid the shock hazard before rem oving the anode cap. 3) D ischarge the high potential of the picture tube before handling the tube. The picture tube is highly evac uated and if broken, glass fragm ents w ill be violently expelled. 2. If any Fuse in this TV receiver is blow n, replace it w ith the FU S E specified in the R eplacem ent P arts List. 3. W hen replacing a high w attage resistor(oxide m etal film resistor) in circuit board, keep the resistor 10m m aw ay from circuit board. 4. K eep w ires aw ay from high voltage or high tem perature com ponents. 5. This receiver m ust operate betw een A C 110~250volts, 50H z/60H z. N E V E R connect to D C supply or any other pow er or frequency.
PRODUCT SAFETY NOTICE
M any electrical and m echanical parts in this chassis have special safety-related characteristics. These characteristics are often passed unnoticed by a visual inspection and the X-R AY R AD IATIO N protection afforded by them cannot necessarily be obtained by using replacem ent com ponents rated for higher voltage, w attage, etc. R eplacem ent parts w hich have these special safety characteristics are identified in this m anual and its supplem ents, electrical com ponents having such features are identified by designated sym bol on the parts list. Before replacing any of these com ponents, read the parts list in this m anual carefully. The use of substitute replacem ent parts w hich do not have the sam e safety characteristics as specified in the parts list m ay created X-R AY R adiation.
