BULLETIN # 837
MODEL: TS-830S
SUBJECT: OPARTION ON 240 VOLTS
To operate the TS-830S on 240V AC, the power transformer
split primaries must be rewired from parallel to series
connection
1. Unplug the AC power cable.
2. Remove the bottom cover.
3. Remove the jumper wires between the two 0 terminals and
two 120 terminals on the bottom of the power transformer.
4. Connect the adjacent 120 and 0 terminals at the middle
of the transformer. This will provide 240V AC operation.
For 220V AC operation, connect the adjacent 100 to 0
winding.
5. Change the AC fuse from 6A to 4A. Tag the power cord at the
back of the radio to indicate that the transformer is
strapped for 240V AC, and the power fuse should be 4A, and
not 6A.
6. Replace the bottom cover and reconnect power to verify
your work.
