Pork Barrel Build - no output on BL3207

[FastEdTex]

Pork Barrel build using BL3207 (MN3207 clone from Small Bear).
Have audio signal on pin 3 - very faint, highly distorted signal on pin 7 & 8.
Jumpers set for 3207 - vertical - Pin 1 test at 0V pin 5 test at 8.9V
Pin 7 & 8 test at just over 4V
What should pin 2, 4 & 6 test at?

BL3207
1 = 0V
2 = 4.35V
3 = 3.78V
4 = 8.25V <----?
5 = 8.91V
6 = 4.34V
7 = 4.54V
8 = 4.54V

Anyone with a working unit with MN3207 or BL3207 voltages that wouldn't mind posting them?

Thanks

The voltages look okay to me.

I've biased my mn3207 to 5.2v on pin 3. Did you try to adjust trimpot?

I thought they were good as well.
I have probed at Q2 and have a clean signal going into 3207, and clean signal at pin 3 going in, just no good signal coming out.
Could the components after the BBD have an effect on the output to affect it in such a was as to reduce it to such a tiny audio signal?
Wrong resistor value?

I will try that again, but I have had it as high as 6.1V on the 4558, but I'll check it on pin 3 of the 3207

I swapped the clock and BBD for a known working 3101 and 3007 and changed the jumpers, all worked.
Put the jumpers pack and the BL 3207 and 3201 back in the sockets.
Adj. the trim pot to get above 4.0V on the pin 3 on the 3207 and viola, good audio!
Well I'll be hog-wallered.

I can move on to boxing it up now.
Thanks Sharpan and Scruffle
