ROG Omega - no sound SOLVED

I'm getting no sound whatsoever. I've sliced and diced the grooves and checked all the gaps with the voltmeter.

I didn't have a 2n7000 for Q2 but read somewhere that a BS170 could replace it so used that.

Voltages:
Q1 G 0.00 S 0.83  D 4.71
Q2 D 9.36 G 6.22  S 8.73

Thanks in advance,

John

Hi John

BS170 has a different pinout than the 2N7000.  Try flipping it around.

Always check the data sheet when subbing transistors/ICs.  The graphic on the drawing won't necessarily be accurate when you're using different ones.  That's why all these layouts have the pins marked too...just in case.

flipoing the 170 did it! Good to know about the transistors, i will check next time I sub. Thanks so much!
