Garrard 5 HF At left you see an edited picture from 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 turntable has 4 speeds: 16 2/3, 33 1/3, 45 and 78 RPM. According to the advertisement the platter weighs 2 kg. There is a knob at the front at right for adjusting the speed (+/- 5%) if there is a deviation. This facility is specifically 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 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 |

Playing Weight There were two versions of the 4 HF. One was just a plain portable record player. The second version was a portable gramophone with amplification. The down force (playing weight) is not adjusted by sliding a counterweight but by increasing or decreasing the tension of a spring. On the short end of the arm is a slightly protruding wheel. If you turn it to the left the down force will be less and if you turn it to the right the playing weight will be increased. |

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 consists of the two loudspeakers. The other has the turntable plus the lid. The built in amplifier of this portable gramophone has four knobs. The fourth is for adjusting the balance between left and right channel of course. The advertisement (from which the image at the left is taken) talked about four speakers. This certainly was meant to impress prospective buyers. More is better. In fact there were the two low-mid units and the two high frequency drivers. All these versions have the Garrard TPA 12 transcription arm. |

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. |

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, Mengelberg 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
with Mozart No. 40 on HMV but also on old pre-war Polydors, etc. And there are
popular records of the early nineteen fifties: Jo Stafford, Rosemary Clooney,
Frankie Lane, Mouloudji, Patachou, Rudolf Schock, etc. etc. |

Demonstration Excellent
demonstration records are the already mentioned Barcarolle by pianist Alexander
Brailowsky (Polydor 35014, 1934), and Walter Gieseking playing Variations
Symphoniques (César Franck) with Sir Henry Wood, on English Columbia.
It is amazing how well the piano is recorded and in balance with the orchestra.
But also the early nineteen fifties hits and jazz records - though not direct
cuts (direct to disc) - have a flabbergasting presence. |

The Mechanism Even
after 50 years of dedicated service, the mechanism is still working perfectly.
(In due time I will add pictures of the 301 and 401 so a comparison can be made
between the 4 (5) HF and the legendary Garrard transcription units.) |

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 with ample bass. |

6 dB Slope For The Tweeter The high frequency unit is a sealed unit and is connected in parallel to the low-mid driver. Just one capacitor (electrolytic condenser) of 8 uF 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 the nice mid-band. 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 best 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 the case of shellac records the best down force is emperically found, as the Garrard scale's indication is 12 gr. maximum. For that a small brass weight of 5 gr. was supplied to calibrate the gauge. |

The Strobe For users of the early 301, the 4HF and 5HF and also the TA Mk4, Garrard suplied a neat stroboscope for calibrating the correct speed in countries with 220 Volt/50 Hz. power. It was a "stroboscopic speed indicator", a small plasic disc of about 96 mm in diameter. It gave the exact speeds of 33 1/3, 45 and 78 RPM. Such a disc was necessary if the platter did not have strobiscopic markings and after the recommended 10 minutes run-in time the speed had to be calibrated anew. |

Template for Garrard 301 In due time there will be more info about the Garrard 301 on this page. Nevertheless you may be interested in the real size mounting template for the Garrard 301 transcription turntable. |
And then there is the Garrard TA Mk 4

Garrard Ta Mk 4 The
Ta Mk 4 is a very ood turntable for playing 16 2/3, 33 1/3, 45 and 78 rpm records.
Motor, platter and tonearm are in working order. This Garrard TA Mk 4 is for sale. Mail me if you are interested.
