e.g. PM5326
Bandpass 250Hz-15kHz
e.g. 7122 707 48001
LF Voltmeter
e.g. PM2534
Ri=50
S/N and distortion meter
e.g. Sound Technology ST1700B
Use a bandpass filter to eliminate hum (50Hz, 100Hz) and disturbance from the pilottone (19kHz, 38kHz).

To avoid atmospheric interference all AM-measurements have to be carried out in a Faraday“s cage. Use a bandpass filter (or at least a high pass filter with 250Hz) to eliminate hum (50Hz, 100Hz).

WARNING
GB WARNING
All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wristband with resistance. Keep components and tools at this potential.
ESD
NL WAARSCHUWING
Alle IC“s en vele andere halfgeleiders zijn gevoelig voor electrostatische ontladingen (ESD). Onzorgvuldig behandelen tijdens reparatie kan de levensduur drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie via een polsband met weerstand verbonden bent met hetzelfde potentiaal als de massa van het apparaat. Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.
F
ATTENTION D WARNUNG
Alle ICs und viele andere Halbleiter sind empfindlich gegenüber elektrostatischen Entladungen (ESD). Unsorgfältige Behandlung im Reparaturfall kann die Lebensdauer drastisch reduzieren. Sorgen Sie dafür, daß sie im Reparaturfall über ein Pulsarmband mit Widerstand mit dem Massepotential des Gerätes verbunden sind. Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem Potential.
Tous les IC et beaucoup d“autres semi-conducteurs sont sensibles aux décharges statiques (ESD). Leur longévite pourrait źtre considérablement écourtée par le fait qu“aucune précaution nést prise ą leur manipulation. Lors de réparations, s“assurer de bien źtre relié au mźme potentiel que la masse de l“appareil et enfileer le bracelet serti d“une résistance de sécurité. Veiller ą ce que les composants ainsi que les outils que l“on utilise soient également ą ce potentiel.
I
AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche statiche (ESD). La loro longevitą potrebbe essere fortemente ridatta in caso di non osservazione della pił grande cauzione alla loro manipolazione. Durante le riparationi occorre quindi essere collegato allo stesso potenziale che quello della massa delįpparecchio tramite un braccialetto a resistenza. Assicurarsi che i componenti e anche gli utensili con quali si lavora siano anche a questo potenziale.
