BA-3 Amplifier illustrated build guide

@bergy

As Dennis points out, Randy Thatcher has fantastic PCBs for the Aleph series that can be scaled as big as you desire. If you've got the chassis for Aleph 2, these boards will let you build it. He also has lots of other items that facilitate the build, the most important of which is matched output devices.

thank you,
those purple pcb are fantastic, and mosfets are also available, (an huge help for me),
this kit is Aleph 30 and Aleph 60, how to get Aleph 2 ?

Bergy, read the build notes at the beginning of the builder's thread. There are a couple of neat little features on the UMS boards. A jumper for setting the AC current gain is one of the features. It is also nice to have the resistor position numbers as well as the caps etc match the thread for research etc.

Go to the build thread and search Aleph 2. Seems that there are a bunch of posts referring to it.

This is starting to turn into the Aleph/BA3 thread 😱 Would it be a good idea to make Aleph responses happen in the Aleph UMS thread?
