How do you know it's bad if you haven't heard of it? I expressed my doubts, and my Ukrainian clients have already started listening to this And he likes the sound of HVRV PESS-01 headphones

And last.

It will be sold in China first There is no doubt that this is true🤝

Haven't heard it, but I'm guessing it sound like ass

Color me skeptical.

OK. It looks like a headphone and small form factor amp. Anything to say about this combo, or are you just posting pretty pictures? The artwork is nice, but I don't think the artist would have gotten full benefit of said headphones/amp.

The newer vaccines are two part, with a month in between shots. I'm told this is superior to the one shot vaccine. I too had no reaction. However, I've never had any reaction to any vaccine. As someone who while in his 40s spent 30 minutes looking for my cell phone, while it was in my hand the whole time, I cannot confirm this lower dementia risk factor.

Thanks for your reply. I plan to test different combinations of static current and cathode resistor values to better understand how they interact. If I get some results I’ll come back and share them. For now, I’m planning to try around 27–30 mA of static current. It’s a bit difficult to find high-precision resistors around 1.2 kΩ, so on the cathode side I’ll probably increase to about 8 kΩ and see how it behaves.

Fan of this kid. Very sardonic sensibility and seems to really care about the musicianship.

Once properly warmed up for an hour or so, the transistor legs sit at around 110, transistor casing at 100 and hottest part of plastic tab at 90 (all in degrees Celsius and with at least +/- 5 degrees or error possible; the IR-gun I use is not the most sophisticated). Definitely too hot to touch, though still a bit cooler than the EL34s . So a bit of margin on both die temperature and what PLA Pro can withstand, though I guess the latter will age quite a bit faster than it would at ambient temperature if I would leave the amp turned on 24/7. I normally don't post pictures because my case work is rather poor, but I found a long exposure mode on my phone which after some experimentation captures the tube glow without leaving the rest in darkness, so I thought I'd make an exception. Pardon the somewhat battered front panel. Should also add that it sounds great.

Thanks for the pin tip. This beyond my understanding. But as I see it, with 400V/22mA the Vgk will be what it will be with offset zero. 12 W with EL34 shouldn’t be much of a problem. My EL61 will also handle that, I hope.

Oh boy. New OL post. Yes, I am going to repost all of them here.

Thanks for your comments, @simmconn. The heatsink gets warm and user is aware of it. I think he is running at 400V/22mA and so far, it seems to work. If it gets too hot than he can’t use this thing - that’s life. For pin dimension. The first version used Neutrik XLR3 pins. They were perfect, diameter slightly undersized. But to short to be soldered direct to main PCB. When looking for brass rod the best I found was 2.5 mm so, I decided to try that. 2.5 mm works with my Teflon tube sockets. The user is informed of that pins are soldered only on one side and if pins come loose, we have to find a better solution or perhaps abandon this thing. I use Addnorth HT-PLA Pro filament. Better heat performance than PLA but not as good as ABS. I’m confident the socket isn’t a problem. It might be a problem with the transistor tab cover. I haven’t thought about the cover until your post - thank you simmconn. Now the user is informed, and he promised to keep an eye on the cover.

I don’t think the non-grata is an issue. It’s just that improving from a Benchmark isn’t easy and most of us haven’t been into audio much lately, or at least enough to offer any insight worth reading.
