Happy to find finally a schematic for this amplifier. The schematic is of good quality, the pcb layout is useless: all is black. Never the less, it is very easy to find the components on the board using the schematics.
;
Hard to find manual was ready the next day. Scans were very legible (including schematics). All the essential parts of the service manual were present (adjustment procedure, schematics, and parts list). It would have been nice if the rest of the manual was included (disassembly procedure, theory of operation, etc.).
 ;
The Service Manual for the Kenwood KR-V55R provided by owner-manuals.com was as described/advertised. The contents provided the necessary information to effect a diagnosis of the unit. The schematics above all else was instrumental in tracing the the signal flow from component to component.
;
This manual was the factory original. Excellent value and contained all the details I needed. Easy dowwnload provided the information when I needed it.
;
Impeccable, document très complet. Perfect, i get all i need. All schematic are correct. Thanks

ADJUSTMENT
s How to assemble the antenna connector and its terminal.
The antenna connector and its terminal are supplied as separate parts. When replacing the antenna connector and/ or terminal, assemble the parts prior to the replacement. 1. Mount the antenna connector onto the chassis �. � Double-sided adhesive tape is attached to the terminal; peel off the tape cover �. � Attach the terminal to the antenna connector as shown below. � Slide the antenna terminal along the adhesive cushion on the chassis so that the adhesive part on the terminal is firmly attached to the antenna connector �. 2. Remove the antenna connector from the chassis with its terminal attached, then solder the center part of antenna connector to its terminal � . Do not use excessive solder on terminal.
Repair Jig (Chassis)
Use jig (part No.: A10-4060-04) for repairing the TK-3140. Place the TX-RX unit on the jig and fit it with screws. The jig facilitates the voltage check and protects the final amplifier FET when the voltage on the flow side of the TX-RX unit is checked during repairs.
How to Remove the Cable
1. Gently draw out both sides of the connector lever uniformly in the direction of the arrow with tweezers. (CN303, CN304, CN305, CN306)
