The two rollers can be replaced by either the QTIM or QLEN tape measuring rollers. The QTIM is supplied in
the place of the take–up reel tension roller as standard equipment. QLEN instead of QTIM is optional. (To be
stated when ordering).
26. ERASE HEAD
This is a full track erase head.
27. STROBOSCOPE ROLLER
This roller comes in two versions : 50 Hz (CCIR machines) and 60 Hz (NAB machines). Using this roller, it is
possible to check that the machine is running at the correct speed, either in record or playback. This works at
all speeds and uses the stroboscopic effect whenever a mains powered lamp is shone upon it. When at the cor-
rect speed, the bars on the roller should appear stationary.
28. RECORDING HEAD
Audio recording head.
29. PILOT HEAD
Neopilot head used for both recording and playback of pilot signals.
30. PLAYBACK HEAD
Audio playback head.
31. CAPSTAN SHAFT
Tape main drive.
32. PINCHWHEEL AND TAPE GUIDE CONTROL LEVER
This lever engages and disengages the tape from the heads and motor capstan shaft. It also moves the
stroboscope roller and mobile tape guide in and out, to allow easy loading of the tape.
When it is in the open position, rapid rewinding is possible. (This lever should never be left in the open position
for long periods of time as this may cause a "FLAT" on the capstan shaft "0" ring).
33. TAPE TENSION ROLLER (OR TIMER) (see 25)
34. TAKE–UP REEL (see 24)
