1/ I believe there is a mistake on the schematic N°1067 for the collector circuit of the mixer (MIX) transistor AF114.

The resistor 470 Ohms, below the first IF transformer should be connected to the -8V line, and not to the ground.

2/ In  the first audio stage (BF1), for the polarisation of the Base of first OC75 transistor,

the resistors forming the polarisation bridge should be 56k and 10k, instead of 5,6k and 10k.

3/ one further information about TR88: on some model, the AF114 was replaced by AF102.

Was this depending on availability?
