BULLETIN # 40
MODEL: TS-120S
SUBJECT: ANTENNA INPUT TRANSFORMER REPLACEMENT

TS-120S transceivers subject to strong static fields or similar high
current atmospheric discharges may suddenly exhibit low RX sensitivity on
all bands.  TX will be OK.  You may suspect T1 on the RF unit X44-1260-01.

When replacing or ordering T1, L43-0696-35, also check the value of C20.
If it is 33pF, just replace and repeak the transformer.

First production transceivers will have a 15pF cap for C20.  When changing
T1, also replace C20 with a 33pF capacitor, and repeak the circuit.

Old part number:    L34-0696-05    Antenna Coil
New part number:    L34-0696-35
Old Capacitor was 15pF, replace with
New part number:    CC45RH1H330J   33pf

Please make these changes in your service manual.
