ok. got some measurements. While measuring resistance from base of Q30 to ground (top node of C30 to GND)? is around 836 ohm. While base of Q10 to GND (top node of C10) has 102 ohm (different transformer). Richard, if You will have much lower than 100 ohm - C30 (100nF) is also suspected to have short.
