ROWE JUKE AMPLIFIERS
REPEATED FAILURE CHECK OUT

Weirton, West Virginia
SUBJECT
SOURCE
Rowe amplifiers repeated fail-
ure.
PROCEDURE
If you need a unit fixed or need
info call Tuesday thru Satur-
day at 1-800-967-2855 and I
will answer your questions.
First
Check all speakers to make
sure they are not shorted. Do
this from the jukebox using an
ohmmeter set in the low range.
Check for 4 to 8 ohms on each
speaker.
With some recent new custom-
ers we have noted alot of OBA
bill units, sent to us for repair,
come in with the rollers
gummed with oil.
~cond
, With a good amplifier in the
jukebox, play a song with a lot
of bass at maximum volume
and check the overload lights
to make sure they are off. (I
like to use Garth Brooks Thun-
der Rolls for the bass at the
end of the song.)

PLEAsENOTE
We strongly advise against
using oil. It is better to use a
Teflon lube in any and all bill
units.
