R o c k - O la D e L u x e A m p lif ie r : Unquestionably the most powerful
and simplest amplifier in the industry! Peak output actually 25 watts! Achieves
richer, clearer, deeper, stronger tone without the distortion found in old style
amplifiers which use twice as many tubes and much more complicated con
struction. The superiority of Rock-Ola’s amplifier is achieved mainly through
the use of the radio industry’s newest super-power-output tube, the “6B5”—
adopted by Rock-Ola over a year ago and now used on the finest and costliest
radios. Contrast this 6B5 tube to the old style tubes found in ordinary old style
amplifiers—and you will readily appreciate the superior engineering skill
responsible for this sensational Rock-Ola amplifier. Outside volume control.
Inside tone control. Built entirely in the mammoth Rock-Ola Factory.

Less P a r ts : ROCK-OLA Multi-Selectors are known everywhere as "the
phonographs with the simplest mechanism.” Rock-Ola engineers have elim
inated all unnecessary parts. That's why, when you take off the back door, it
all looks so very simple! There is nothing to jam. Nothing to wear out!
O n e P o s it iv e C a m M o v e m e n t : The entire changer mechanism is
controlled by a single cam assembly. Simple . . . nothing to get out of adjust
ment. The cam is worm-driven by a V-belt from the power motor. Both cam
and worm gear are of tough metal, instead of fragile bakelite or composition.
D u a l M o to rs : Control motor is designed for the changing of records
only, while the turntable motor is specially designed to give a 100% noiseless,
smooth, even-running turntable. Regardless of voltage variation, the turntable
always runs at the same even speed. Dual-motors eliminate the need for
clutches and other unnecessary parts. The Dual-motor feature is one of the
outstanding ROCK-OLA points of superiority!
N o V ib r a t io n : By the scientific use of rubber mountings and insula
tion throughout the ROCK-OLA Multi-Selector, all the vibration usually
found in ordinary phonographs is eliminated. This insulation, combined with
the use of Dual-motors, is greatly responsible for the perfect tone quality.
M ic r o S e n s it iv e S w itc h e s : The use of the famous Burgess Micro
Switch, known and respected by experienced music operators the country
over, is an example of the high quality of every part of the ROCK-OLA Mult'"
Selector. There can never be burning or sticking of contact points with the
use of this switch.
R e c o r d T r ip p in g S w itc h : Found exclusively on ROCK-OLA Multi
Selectors! Prevents the continued playing of one record by moving the tone
arm over again, after it has played part of the record. You get one full recor
of music—no more! Ruggedly built. Simple. No hair-trigger adjustments.
M u lt ip le C o in C h u te : Takes nickels, dimes, and quarters. It is con
veniently located on top of the cabinet where anyone can see it, and where i
is easily accessible. The most efficient and simple chute of its kind. Monarc
style.
S p e c ia l C u r r e n t: Standard models operate on 110 Volt, 60 cycle A.C.
Available for D.C. at small additional cost.
A p p r o v e d b y N a t io n a l B o a r d o f F ire U n d e rw r ite r s :
