BULLETIN # 1053
MODEL: TS-950SDX
SUBJECT: Change of Gate Resistor Type 

Symptom: If the final amplifier is operated at excessive transmit levels 
(over 150 watts output) the final FET's may fail and short from Source 
to Gate. If this occurs, the bias resistors used in this circuit may be 
damaged and cause a large amount of smoke to be emitted from the final 
compartment.

Corrective Action: Change the carbon type resistors used for R17 and R18 to 
fuse type resistors. This will prevent an unpleasant odor and smoke from 
the final compartment.

Parts Required:

Qty Description                      New Part No.       Circuit Description
2   100 ohm 1/2 watt Fuse Resistors  R92-1310-05        R17, R18


Procedure: Remove the old resistors from their locations on the circuit 
board and install the new resistors directly between the Gate and Source 
of the final transistors.

Caution: If you do not have the proper equipment or knowledge do not attempt 
this modification yourself. Seek qualified assistance from your closest
Kenwood Service Center (Long Beach, CA, or Virginia Beach, VA).

Time required for this moditication is 60 minutes or less.
