I finally cased up my uTracer. So much nicer to work with I still have a few refinements, but it's up and running now.

Happy Birthday Justin

Just finished testing a new version of the battery with the LT1021-7 reference. From what I can measure, it seems quieter on the scope (mostly above 25KHz) than the LED version. It's nice to be able to test without risking the whole amp I'll probably start using the LT1021-7 in the GRHV supply as well since it needs less current to operate. I'm currently feeding it about .94mA with the base of the transistor it connects to pulling about 70uA from that as well.

Very nicely done Nate

Built a test rig for the Active Battery modules. I'll give it a try tomorrow. It will allow me to test the DC & AC for the batteries.

Thanks everyone. Had a really nice day. Just got back from a nice dinner with the family at the local Greek place

Hi Les, Yes, you can safely keep the FQPF8n80c in the power supply. It's what I use in mine.

Ad long as the +/- legs of each channel are somewhat balanced it should not hurt the headphones. That being said, I'm not sure how the negative rail going further negative would push the outputs to +50 or +100. I'm assuming your -500v rail is now unregulated at about -560v and the other rails are all good. Is that right? After you get the PS back in order be sure to check out the amp as well. Good luck and keep us posted.

Happy Birthday Bent! Enjoy ?

It's a chrome finish. I did it in black as well. Here's the PS...

Yeah, Nascent Audio is me. Thanks Hugo!

Happy Birthday Chris! Enjoy

Happy Birthday Ari!

Start with the right channel and check all of the test point voltages. Also, what are the voltages for each rail.

Nice! That's been on my project list for far too long.
