Hi Richard,
Really sorry, my mistake, I have measured C10 again to the ground and this is also ~823 ohm.
But don't bother with C10, nor C30. This is the same as measuring resistance from base of Q10 and Q30 to GND.
In both there is ~823 ohms. Your measurements brings confusion as I was thinking we have only trouble at 2nd RX chain,
are you sure its not 0.82 kOhm? If this is 0.82k then its OK.
?
Anyway 50 ohm on base of Q30 is NOK.
Can You de-solder C30 and measure voltages on Q30 before replacing Q30?
?
Regards
Tomasz
