Note sul diagramma di circuito :
1. Tutte i valori di resistenza sono in ohm,
)
K=1,000, M=1,000,000.
2. Tutte le resistenze nominali watt sono di
1/6 a meno che sia specificato altrimenti.
3. Eccetto per i condensatori elettrolitici, tutti i
valori di capacitanza di meno di sono
espressi in µF, e di piu di 1 sono in pF. I
varoli di capacitanza elettrolitici sono in µF.
4. Tutti volt di capacitanza nominali sono di
50V a meno cha sia indicato altrimenti.
5. Tutti valori di inductanza sono in µH.
6. I valori letti del voltaggio presi con un
"VTVM" proven gono dal punto indicato
sulla massa del chassis, i valori di voltag-
gio presi usando un segnale di barre col-
ore sono con tutti i controlli alle loro
posizioni normali ed il commutatore AFC
in posizione "OFF". Il voltaggio puo variare
con l'intensita del segnale.

7. Le forme di onda furono prese con il seg-
nale di barre colore e i controlli regolati
oppure le forme di onda di immagine nor-
male furono prese usando un oscillatore a
larga banda ed una sonda bassa capasità.
8. Rispetto a quando indicato su questo
schema possono essere state introdotte
delle modifiche.
9.
I diodo 1S1555 possono essere sostitutti
con 1S2473, 1S2076 oppure DS472 a
meno che sia specificato altrimenti.

Circuit diagram notes :
1. All resistance values are in ohms,
K=1,000, M=1,000,000.
2. All resistance rated wattages are 1/6W
unless otherwise noted.
3. Excepting electrolytic capacitors, all
capacitance values of less than 1 are
expressed in µF and more than 1 are pF.
4. All capacitance rated voltages are 50V
unless otherwise noted.
5. All inductance values are in µH.
6. Voltage readings taken a digital voltmeter
are from point indicated chassis ground.
Voltage readings taken by using a colour
bar signal are with all controls at normal
position. Some voltages may vary with
signal strength.
7. Waveforms were taken with colour bar
and controls adjusted for normal picture.
Waveforms were taken by using a wide
band oscilloscope and a low capacity
probe.
