Inspired by Nate, I made Detroit pizza tonight for Dorothy and Steve.

A little catch-up. I listened to this last Friday at the whisky gathering. And again right now. Live At The BBC by Marianne Faithfull https://album.link/i/1444089414 Example: Just lovely.. RIP

Friday we saw the Boston Symphony Orchestra and the Tanglewood Choir perform Beethoven's 9th. So far the only live music event I have been to that made my heart race. When the choir and soloists all stood up in unison to perform the fourth moment, I was shook.

I've ran into an issue building Carbon. I'm using split PS boards + separate GRLV. When I connect PS boards to transformer (without AMP boards) everything is fine, and voltage is +405/-406VDC (bias is a bit low at 563 but that's non-relevant issue and a matter of zener tolerances). But as soon as I connect AMP boards, transformer starts to heat up a lot (I didn't risk to leave it connected for more that 15 sec). Maybe it will start melting. Here is my connection: +400 goes to each AMP's B+ terminal, -400 goes to each AMP's B- terminal (obviously). However GND from each PS from goes to nearest AMP board only and are not tied together or by a sort of star terminal, therefore GNDs are not shorted. Am I missing a point here? Should connecting GNDs of each split boards remedy the transformer heating problem? Easy to check by yourself, one must say, but one of my DN2540N5 went bad and I cannot check it right now. This is my transformer spec (must be plenty of power, so insufficient VA rating must not be a reason?): 1 x AUDIO GRADE WITH EPOXY FILL INTERIOR PRI:230V SEC: > 2x 330V under load (350mA) (separate windings) > 2x 18V under load (500mA) (separate windings) - VA rating around 300VA

Happy Birthday, Jeff! Maybe you could celebrate by making something at https://www.lakesidewoodworking.net/ that Brent can't have, then posting it to https://www.instagram.com/woodworkonthelake/ ?
