Thanks, I'll give the nx a try. Did you install the alternate compensation scema. That makes a big difference on the FEs. I'll try to get it on the V1.3 amps sometime today.

Thanks, I'll give the nx a try. I'm not sure how much of the alternate schema is already on the V1.4 but I'll try to install it on the V1.3 amps later today. It made a big difference on the FEs.

yes, the difference is quite noticeable isn't it? i can see how most people would prefer the alternate placement but for me inner harmonics take priority and i've actually grown quite fond of the 'soft' myref bass

Sory, I wasn't clear in my response. I was refering to the alternate compensation mod. We are going to have to give them their own names.

Found an old BP-150 board with surface mount spots. Here's my little down and dirty production showing the simplicity of the process.

This one is a little plump, but will work just fine. Some solder wick painted with flux works great to remove any extra solder.

P.S. Look out Spielberg!!

Nice work, though, you need someone to hold the tweezers for you to prevent the resistor moving, hence, you have better control on the soldering process, in other words, the amount of solder. You cave me a push toward trying that by myself.

Thanks for the video :- )

Nice video, Bob

Only a suggestion wet (much) less the point, it will avoid that excess of solder.

A good smd solder joint should have only a tiny amount of solder.

Interesting link with lots of pics of excessive solder:

O.K. So it's "Fat" not plump. .........And I wasn't shaking - just zeroing in on the exact center, with quick minute adjustments.
