Testing Amp Module

Here is the Amp Module assembled and in test.

I have been really slow on this, bowing to financial pressures, but moving ahead now. I was just now attempting to set the bias current. One MOSFET responds but the other one doesn’t. I will order more this week and resume test.

My plan is to complete checkout of this module and offer as a sub kit the amp and LP Filter module in a sub-kit for bare-bones control. The amp has a binary resistive pi network on the input from 0 –  15 dB attenuation to match the drive provided.

The Display Module has been put to bed. We have a good board set. It will be offered assembled and tested or as a kit.

More after I get the bad MOSFET replaced.
