Default Re: Vintage Television Technology.

The Pye V4 service manual shows: V1 RF amplifier [EF80] V2 vision and sound mixer [EF80] 16/19 mc/s IF.

Early versions of the dual band model VT4 were 16/19mc/s but to add confusion, later versions were to BREMA spec 34/38mc/s. All two band models employed the PCC84 and PCF80 in the highly successful incremental tuner. John.

I'm fairly certain that only the FV series employed the ECL80 as mixer/oscillator.
