## Comments

Have you fitted the diodes on the amp board?

Any chance of posting a couple of pics?

PS thanks for all the help so far. With the amount of support here I'm confident my amp will be playing sweet music soon.

I'm cheering you on from the sidelines Brumjam!

(It will get sorted! >:D< )

I'm going to check my soldering now on the current adjustment pot. Getting closer to music.

Waiting for further news...

Family has stopped play for time being. To quote Arnie 'I'll be back'.

Make the most of the company. :-)

R3 = 240R

R4 = 2K7

R16 = 470R

R5 = 240R

R6 = 2K7

R16 = 470R

Some of these parts had different values on original BoM, so I had to remove some of these resistors and solder in the new values - I only mention this because my soldering wasn't brilliant given proximity to other parts. Should I focus on checking the solder on these parts?

Thanks, James

The result will be all the more satisfying when I sit down and listen to music through it

I've noticed that on a couple of builds that folks have taken the speaker connections from the amp board and not the connections on the p/s board. Does this make a difference?
