Re: uBITX v6 Low Audio - Back at it again


 

Before I stat removing components, I'll report the following based on your last suggestions:

Resistance from base of Q30 to GND = 50.8 ohms, no where close to 836 ohms.
Resistance from base of Q10 to GND = 0.82 ohms, no where close to 102 ohms.
Resistance across C30, in circuit, = 50.6 ohms.

I light of that, what's your opinions? Start pulling and ordering some parts?

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.... less than 90 ohms.
