you are aware that you need a heatsink touching all the sot transistor. still with heatsink it typically can take about 5 minutes to reach high temps.

The tube 6E5P in triode connection has Ka c.a 50 - I know because I tried it. So probably yes, it is not enough for 300B, when you consider even low NFB. And this tube has a really huge microphonic problems, every single one - not useable in audio first stage amplification, in my opinion ofc.

Hi all new to Estats...looking for the best value estat amplifier,the Blue Hawaii is a name I hear.Can somebody explain why this particular amp is so good for estats unlike Stax,Topping etc. I ask because already theres a low opinion on the new Feliks amplifier...so looking for something really good.Thanks

i am aware of the overheating issues. i have an assembled board coming to me to look into this. something clearly has changed from the original parts i used and there is some positive thermal runaway that did not happen with the prototype. there is a later version board now, 4 layers, still does not fix the problem. putting 12v zeners in series with the 1.1meg resistors may introduce enough negative thermal compensation. otherwise the bias needs to be trimmed a lot. hate the parts situation i do.

Has anyone tried building this? Not sure if it's just me - after power on, the board overheats within a minute and then comes the magic smoke. PSU voltages are correct but output balance (i.e. L+ vs L-) goes from -2 to -60v quite quickly then suddenly normalises to around 4v). Pretty sure there are no shorts or issues with soldering on my board...

You won’t find them boards at Kevin’s library. Custom made.

Thank you. My friend is very grateful. He says he cannot see the center board to be found? He also says that the boards attached to heatsink is also not found?

Those are always uplifting, and I could use that today. Thanks for that.

I knew it was bad, but I didn't know it was fucking-with-someone's-dog bad. That's horrible.

I can only hope the murderer is put in prison and made someone's - or better yet SEVERAL someones' - ass bitch! Scum deserves it deeply.... A dog, too.....

That is heartbreaking! WTH is wrong with some people... Sam

This shit is crazy. King of the Hill actor Jonathan Joss fatally shot in Texas after argument with neighbor. EDIT: The second page didn't paste for some reason:

Have heard good things about it and it was on my list; guess I'll bump it up.

Funny, I just came here to post what I listened to yesterday. The sound quality is pristine. I've always been a fan of HDCD, especiallly in Reference Recording's hands. YMMV, but I very much enjoy the performance as well. I've had this disc for years.

Copland: Our Town Suite, The Red Pony Suite & El Salón México by Aaron Copland (1988) https://album.link/kjqzqbb7js4mt Example: Finally getting back to finish off the trio of CBS Masterworks: Copland v Copland... Like the others, just lovely, maybe not the most audiophile of the recordings out there, but super lush and the performance is unquestionably good. I may poke around a little bit more for other recordings, I have a few others in my queue (Bernstein, MTT, Marriner), but I feel that in the future, I will probably just come back to these.

ew... {begin rant} Well you were right. I didn't have the stomach to watch past a few minutes. As soon as I heard 'Physics Establishment' I knew that it was Crackpot time and I was done. I am sorry I gave it that much time, they probably got credit for a view. I at least was able to give it a thumbs down. There are several vids by Angela Collier about Crackpots - and they are scary people that are mad.... I like Sean Carroll - I read his pop physics books back in the day: From Eternity to Here: The Quest for the Ultimate Theory of Time The Particle at the End of the Universe: How the Hunt for the Higgs Boson Leads Us to the Edge of a New World Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime I would rather read papers than books aimed for public consumption now. But Sean is a well respected in the industry with over a hundred published research papers. He falls in the camp of Brian Greene for me as a science educator. In some ways I hate that he did this. It raises the status of 'people that yell' that their theory is worthy of debate. {end rant} Back to working on my theory of everything that they cannot handle....

Glad you posted that Jimmy. I've read all of the Dept Q novels by Jussi Adler-Olsen, which are set in Denmark, but it seems they kept the characters and themes the same. Gonna check it out.

Dept. Q (Netflix) - An Edinburgh-based detective involved in a shooting gets re-assigned to a newly-formed cold-case department. A crazy set of twists & turns connects all the dots. We liked it alot. Hopefully there will be an S2.

a friend of mine is planing to build a similar amp but cannot find the pcb files for the pcb in center can you please link those?

If I wasn't certain that I haven't been drunk since I was 16, I'd swear I was shit-faced in that second picture. I've come to terms with having a bald spot, but Foster Brooks has to go!

Steve wanted a couple to action shots.
