Specifications are used to indicate a recorder's performance characteristics ... but your F-44 is more than a mass-produced recorder manufactured to meet minimum specifications printed on a piece of literature ... each F-44 series recorder has been optimized at every stage of production to obtain its maximum performance characteristics ... each recorder is one of a kind ... it's your recorder.
Begins ... with the inspection, testing and alignment of component parts before they are assembled to insure they meet Ampex design specifications... shown at left (1) a technician adjusts the Bias Oscillator Transformer for maximum second harmonic rejection (minimum harmonic distortion)... even the die-cast frame is re-checked prior to assembly to verify the micro-milling operation, here (2) a plane gauge is used to determine whether the magnetic head mounting and tape guides are within the 1/1000" tolerance required.
Continues ... through every stage of sub-assembly, here (3) the F-44's Channel Selector Switch is inspected and checked for workmanship... then, the very same switch is checked again (4) when it has been assembled in the electronics chassis... the completed electronics chassis is then aligned and tuned (5) following a 33-page, step-by-step procedure that simulates all normal operating conditions with inputs and outputs measured, aligned and tuned to optimum performance.
Includes ... mechanical as well as electrical adjustment and alignment to assure optimum performance from the tape transport system ... after assembly of electrical and mechanical sections, the completed recorder is subjected to a 16-hour "break-in" (6) with the clutch tied into operating mode so that it is stable when finely adjusted (electronics are on during break-in period)... at the end of 16 hours, the transport's mechanical components are once more aligned (brake, clutch, hold-back tension spring, capstan drive, counter, etc.)... here (7) a tension gauge is used to measure (for adjustment, if necessary) the spring on the capstan idler drive to insure proper tension on the capstan, thus eliminating unnecessary pressure on the tape or tape slippage.
Meantime ... the 3 magnetic heads for your F-44 recorder are being inspected and aligned to tolerances so precise they require special. Ampex-designed micro-optical measuring equipment... an optical comparator is used to align the height, azimuth and perpendicularity of the F-44's heads to the tape guides... head gap requirements are held to less than 10 millionths of an inch and here (8) a 50-power microscope is used to align the gap in the center of the area where the tape will make contact with the head (to attain equal distribution of tape wear on both sides of the head gap).
Ends ... at three, final inspection and alignment stations ... one (9) is in a sound-proof chamber where the mechanical function of the tape transport is once more aligned and adjusted for: speed accuracy to within 1%; optimum torque from the hysteresis synchronous motor to operate all functions with a minimum of line voltage; audible mechanical noise... the second station, where: recording and playback response are optimized through 15,000 cps; record bias is adjusted to minimum distortion; the second playback amplification stage is adjusted to optimize the output of the playback head and electronics on each channel ... and the last station, where your F-44's performance characteristics are once more verified to assure you the peak of performance from your F-44.
This Requires... 41 testing, measuring and alignment instruments representing over $156,500... the full time of 13 technicians... and a dedication to make each F-44 the finest quality stereo tape recorder/player money can buy.
Because each F-44 recorder is a one-of-a-kind, an individual record is kept of its performance characteristics. As each F-44 is optimized to its own peak of performance, a record is kept of the important performance characteristics: Overall Frequency Response/Signal-to-Noise Ratio/Flutter-Wow Measurement/Crosstalk Rejection. You will obtain your F-44's own specifications when you return the 1-year Warranty Registration card to Ampex.

RIES
Reliability and durability are important "extra" ingredients that Ampex adds to each F-44 recorder to assure you of continued peak performance year after year after year. That's why random production line models are dropped, bumped, shook, frozen, cooked, inspected, probed, checked, measured and tested by Ampex's Quality Assurance engineers (an independent group charged with the sole responsibility of maintaining the incomparable Ampex standards of quality).
