Not indicated except for electrolytics.
¢ Allelectrolytics are in 50V unless otherwise specified.
« Allresistors are in ohms, 1/4W in resistance, 1/10W in chip resistance.

* All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
+ The components identified by b4 in this basic schematic diagram have
been carefully factory-selected for each set in order to satisfy regulations
regarding X-ray radiation.
Should replacement be required, replace only with the value originally
used.
+ When replacing components identified by 14 , make the necessary
adjustments indicated. If results do not meet the specified value, change
the component identified by }€ and repeat the adjustment until the
specified value is achieved. (Refer to R1535, R1536 adjust on Page 36 .)
« When replacing the part in below table, be sure to perform the related
adjustment.
