Very fast and perfect delivery. Clear and well scanned. A lot of work professionally realized.
Again thak you a lot

This manual is accurate and of high quality. It is only volume 2 of the service manual. This is schematic, parts lists, and exploded mechanical drawings. The theory of operation and the diss-assembly instructions are in volume 1. The unit can be tricky to dis-assemble portions of so the volume 1 manual can be important. The product description of the manual is accurate but it does not say anything about volume 1 and the image of the front page does clearly say Volume 2.

Wellll again thank you very much fast and effective. Clear and well done for such an old TV!!!!

It has all the information you will need to fix it. The main circuit diagram is only A4 but being a PDF, you can print it to any size - I did it on two sheets of A3 and it didnt lose any detail - just made it readable when pinned up above the bench. I've found the fault, just need to buy some obscure bits to get it going again!
I cant fault the process, I paid for the manual in the morning and it was ready to download by lunch time.

Very good copy in a 54 pages PDF archive. This is my sixth purchase here. :)
SECTION 3 MECHANICAL ADJUSTMENTS
1. PRECAUTION Clean the following parts with a denatured-alcohol-moistened swab: record/playback/earth head pinch roller rubber belts capstan idlers Demagnetize the record/playback head with a head demagnetizer. (Do not bring the head demagnetizer close to the erase head.) Do not use a magnetized screwdriver for the adjustments. After the adjustments, apply suitable locking compound to the parts adjusted. The adjustments should be performed with the rated power supply voltage unless otherwise noted.
SECTION 4 ELECTRICAL ADJUSTMENTS
PRECAUTION 1. The adjustment should be performed in the publication. (Be sure to male playback adjustment at first.) 2. The adjustments and measurement should be performed for both L-CH and R-CH. � Switch position DOLBY NR switch : OFF DIRECTION switch :A � Standard record position Deliver the standard input signal level to input jack and set the REC LEVEL (RV301) control to obtain the standard output signal level as follows. � Record Mode �

Thus, the TEST mode will be activated. If a recording is done in the TEST mode, the REC MEMORY mode becomes active where the tape is rewound by the amount of recording when a rewinding is executed after recording. After adjustment, make the CN801 (2P) open to release the TEST mode.
