Low frequency converted PB CHROMA supplied to IC6
pin passes through the balance modulator within
IC6, is converted to a 3.58 CHROMA signal, passes
through FL6 (3.58 MHz+500 kHz), is amplified bet-
ween pin (10 and pin (9), passes through DLI (3.58M
1H delay) is fed to pin(6), output from pin (7), level ad-
justed by VR14, and output to VIDEO OUT.
