Here is the M400 module, it uses a pair of 2SK1058 and pair of 2SJ162. This is my "spare" one(I ordered an extra one just in case). I am very happy with sound

So! cabinet is pretty much done. I need to make another shelf and a drawer. The top rack unit has pull out lights! Both of the Crown amps are modified by me (bigger filter caps, different op amp, signal capacitor swaps, etc.)

Now I need some speakers to go with this...

Here's the front door. Book matched birch veneer with pine trim.

Well, they may be old designs but they are the same as the new ones from Crown. I changed the opamps and several other things.

Oh, and thanks but the wood work is not perfect. Of course, I see all the flaws...

Hi! This is my prototype a board of Hybrid Power Amp, based on Holton. Mosfet-Bipolar Hybrid 2SC5200/2SK1943 IRF9610/610.

I'm making progress on my chip amp. I got to use my new drill press for the first time. I can finally make nice holes in sheet metal now. I installed 2 rivet nuts in M6 size for the transformers. It just so happened that they bolts they provided are also M6. I didn't plan that! wow. Anyway, I'm using the rivet nuts "backwards" so nothing pokes out of the box. There's a Twisted Pear USB receiver DAC in the center, with the Audio Sector LM3875 amps.

rivet nuts backwards

What side of the panel is the threaded fastener?
What carries the bolt tension into the panel?
How strong is the squishy aluminium that the rivet is made from?
