The REVOX 736 (G36) is a mono/stereo machine with stacked erase heads, separate recording heads separate replay heads, six audio pre-amplifiers. and a push/pull power amplifier. Tape speeds of 3 3/4 and 7 1/2 .i. p. s. are obtained by pole-changing the synchronous Papst capstan motor. Twin-track and four-track models are available, both fully stereo phonic, recording to the latest C.C.I.R. (DIN 45113) characteristic.

Specification (via Reeltoreel )
Tape speed
3 3/4 and 7 1/2 ips, pole-switching capstan motor, direct drive (motor may be switched off, if recorder is used as an amplifier)

Flutter and wow
below ± 0,1% at 7 1/2 ips

Rewind time
approx. 80 seconds of a 2400 feet reel

Max. reeldiameter
up to 25 cm (10 1/2")

Frequency response
40 - 15'000 cycles at 7 1/2 ips +2/-3 db
40 - 12'000 cycles at 3 3/4 ips +2/-3 db

Equalization
in accordance with CCIR standards.
70 micro-seconds at 7 1/2 ips.
140 micro-seconds at 3 3/4 ips.

Signal to noise ratio
Better than 52 db at peak record level (2 track)
Better than 50 db at peak record level (4 track)

Dynamic range (overall)
2-track recorder: 55 db at 7 1/2 ips | 53 db at 3 3/4 ips
4-track recorder: 52 db at 7 1/2 ips | 50 db at 3 3/4 ips
(Thd.= 3%)

Crosstalk
Mono 55 db | Stereo 40 db

Oscillator-bias frequency
70'000 cycles push-pull oscillator

Inputs per channel
1. microphone = 1 Megohm, 3 mV
2. Radio = 1 Megohm, 50 mV
3. Diode = 47 K'ohms, 3 - 50 mV, adjustable

Outputs
2 cathode-follower outputs, impedance = 5'000 ohms (input impedance of amplifier to be connected should be higher than 100'000 ohms.)

Output voltage
= 0.6 volts - (2 track)
= 0,4 volts - (4 track)
1 loudspeaker output 5 ohms, 6 watt Push-pull power amplifier, internal speaker may be switched off.

Tube complements
4 x ECC 81, 1 x ECC 82, 5 x ECC 83, 2 x ECL 86, 1 x EM 801,
3 diodes, 3 selenium rectifiers

Power line voltage
110, 240 volts, 50 cycles

Power requirements
approximately 120 watt

Fuses
for 220-240 volts: 0.6 Amps) 5 x 20 mm slow-blow
for 110-145 volts: 1,2 Amps) 5 x 20 mm slow-blow

All these data are valid for the 2-track as well as the 4-track recorder, unless noted otherwise.
