1. When repairing the circuit, be sure not to increase the high voltage to more than 30.0kV
VHF/UHF .......................................................................... 75 ohms Unbalanced
(at beam 0 mA) for the set.
Receiving System2. To keep the set in a normal operation , be sure to make it function on 27.0kV ?1.0kV (at
PAL I, B/G, D/K & SECAM B/G, D/K, -K1 & NTSC Mbeam 1,000 mA) in the case of the set. The set has been factory - Adjusted to the above-
mentioned high voltage.
Receiving Channel
\\\\\ If there is a possibility that the high voltage fluctuates as a result of the repairs,
VHF-Channels .......................................E2(48.25MHz) thru E12(224.25MHz)
never forget to check for such high voltage after the work.
C1(49.75 MHz) thru C12(216.25 MHz)3. Do not substitute a picture tube with unauthorized types and/or brands which may cause
S1(105.25 MHz) thru S41(463.25 MHz)excess X-ray radiation.
