Idler Wheel Drive, Heavy Arm and a Crystal Pick Up
![]() |
Garrard 5 HF At left you see an edited picture form an advertisement in a record collector's magazine from 1963. It is the beautifully designed Garrard 5 HF record player on a matching plinth. The deck has a heavy arm, suitable for a ceramic or crystal pick up. But also low compliance moving magnet types of phono cartridges can be used. The turntable has 4 speeds: 16 2/3, 33 1/3, 45 and 78 RPM. There is a knob to adjust the speed if there is a deviation. This facility is especially important when playing old shellac records which were not always cut at 78 rpm, but at 80 rpm or whatever speed the manufacturer of the early days adopted. The single record player 4 HF is similar to No. 5. There were two versions of the 4 HF. One was just a plain portable record player. The second version was a portable gramophone as it had amplification. |

Portable Mono This is the mono edition of the Music Master. The lid contains 2 loudspeaker units. One for the low and mid frequencies and one for the high frequencies. There are three potentiometers. At left is the knob for setting the volume. The second from left is for adjusting the treble. The third one controls the bass. |

Portable Stereo This is the stereo version of the Music Master. It consists of two portable units. One contains the two loudspeakers and the other one has the turntable. The advertisement (from which the image at the left is taken) talked about four speakers to impress prospective buyers. In fact there were the two low-mid units and the two high frequency drivers. |

For Old Mono Lp Recordings These
Garrard recordplayers have an automatic shut off which can be disabled
by pressing the small red button next to the arm base marked "non
automatic". |

78
RPM Fanatics Love This Machine Many music
lovers have evolved with the market and are used to listening to stereo
long playing records and to the Digital Audio Compact Disc. A few have
experienced the sound of 78 rpm direct to disc recordings from before
World War Two. No tape recorder was involved. A range of cutting lathes
were installed in ghe monitoring room or close to the performers. The
music was cut into the laquers on the spot. |

Wide Range With the
advent of the Compact Disc many people started collecting vinyl abundantly.
And often they came accross old 78 rpm discs too and bought a suitable
gramophone to play them. That is what happened to me also. There are
various items worth listening to: Eduard van Beinum conducting the Concertgebouw
Orchestra in The Swan of Tuonela (Sibelius), Herbert von Karajan with
the same orchestra in Don Juan (Strauss), Paul van Kempen with the Berlin
Philharmonic (1936) performing Les Preludes (Liszt), Withold Malcuzynski
playing Chopin, Eileen Joyce on Columbia, Emil Telmányi on a
10" Tono, Ida Handel with Wieniawski's Polonaise, Yehudi Menuhin
playing Mozart with his teacher George Enesco conducting, and Furtwangler,
Mengelberg, etc. |

Demonstration On the
lighter Philips side there are of course the stars of the nineteen fifties:
Jo Stafford, Frankie Lane, Patachou, Mouloudji, etc. And jazz artists
on Mercury, London, Philips, Decca. |

The Mechanism Even after
50 years of dedicated service, the mechanism is still working perfectly.
(I will add pictures of the 301 and 401 in due time so a comparison
can be made between the 4 (5) HF and the legendary Garrard transcription
units.) The fact that the platter is set into motion by means of an
idler wheel, and the materials used for the construction of the machine,
result in a very pleasant and natural sound with the appropriate weight
in the lower mid frequency band. Note: I will add some explanation about
the handles, strips and switches at a later date. |

2-Way Loudspeaker System Simplicity
makes sense: a two way speaker system in a quasi open baffle. An oval
driver for the low and mid frequencies and a high frequency unit. The
addition of the back panel improves the dynamics and gives a good reproduction
of the low frequencies in relation to a firm mid band. Positioning the
lid with the speakers closer to a corner makes it possible to find the
best sound balance. |

6 dB Slope For The Tweeter The capacity of the electrolytic condenser is 8 uF. The high frequency unit is a sealed unit and is connected in parallel to the low-mid driver. Only one capacitor in series provides a 6 dB slope, ensuring a correct phase. Do not swap it for a polypropylene capacitor. You may loose some of the speed of the sound. And polypropylene will influence the dynamics and the frequency curve. |

The Front-End is Important Choosing the best suitable ceramic cartridge or crystal pick up is of course important. Various makes do come to mind. Ronette and Acos are the bes known. At left the Merul and at right a simple Ronette. |

The Scale For the 301, 401, 4 and 5 HF, the Garrard engineers designed the SPG3 Stylus Pressure Gauge. It was packed in a small cardboard box with instructions. For todays standards with precise measuring of a cartridge's playing weight with a digital scale, the increments of 0.5 gram of the SPG3 result in a rather rough adjustment. In the early Lp days, playing weights of 4 to 10 gr. were possible. For 78 rpm shellac records a down force of 9 gr. can be necessary. In that case the best sound is emperically found, as the Garrard scale's indication is 5 gr. maximum. For that a small brass weight of 5 gr. was supplied to calibrate the gauge. |
