assuming the parts are stn9360 and matching npn are 600v parts the front end limits to +/-600v. with cascodes you can get to +/-900. anything over +/-600v will damage the headphones.

So, I've been testing it for two days. It's thermally stable for 12 hours. I think the tests can be completed. I just don't know what the upper power limit is. I tried +-400V and it works. And even at +-450V. I wonder if it can withstand +-500V or 600-700-800V? I saw someone build it with four 400V modules. So, +-800V.

I didn't love their beer but it is another sad sign of the times in craft beer.

You may use the Epoxy Glue to fix it.

This one might work: https://eu.mouser.com/ProductDetail/EDAC/305-014-500-202?qs=XeJtXLiO41RmPm5Oq5cTfQ%3D%3D 14 posistions, 1.6mm board thickness and 3.96mm pitch between the pins

Hi Kevin Well, it still works. It's just that the voltage distribution isn't ideal for -400V and +400V. I'm not sure if it's possible to supply different voltages. The sound is good and quite clear. But I think I'll still have to buy those proper modules and settle the power supply issue—there's no way to get +-400V 6mA for under $50.

that is a dual voltage output, single ended flyback supply. can't change the positive voltage without changing the negative. so you really need 2 x single output units. and then you might be stuck with +/-380. which should work.

Perhaps Better to get down go 380 the other one, no?

So I connected this yellow DC-DC. It can produce -400 and +380 volts from 12 volts. Which is 20 volts less than I need. Interestingly, it can produce -400 volts in one side. And only +380 volts in the other. Funny. Now I'll be looking for ways to squeeze another 20 volts out of it. Or should I just skip the hassle and buy some decent USA S400 modules and be done with it.....

I'm not ready for a new espresso machine as the Lelit Bianca I bought some years ago is still doing a great job, but I found an announcement from Fellow interesting. I bought a Fellow Aiden I have been enjoying thanks to @luvdunhill , and have been receiving Fellow marketing emails. Here is an early review for the curious. I have to admit it piqued my interest, particularly how quickly it heats up. Looks like it can be bought for $1200 with an early discount and they toss in a credit for coffee beans. https://www.engadget.com/home/kitchen-tech/the-espresso-series-1-is-the-new-crown-jewel-in-fellows-coffee-gadget-lineup-170008473.html HS

I have decided that I’m going to shoot digital only soon. I have a significant amount of film in my freezer, but once it’s gone my film cams are conversation pieces only. I can fortunately shoot the vintage Nikon glass on the Df. Thinking about going to a Hasselblad 907x. I guess I’ll get a Ricoh to replace the Rollei. It’ll be a lot less charming. I’m able to get shots with that camera that I couldn’t with anything larger and less charming. I hope a GR meets those requirements.

Hi, The time has come for my broken SRA-3S, unfortunately I don’t like what I have found inside there Any idea if this kind of slot is for sale nowadays anywhere?

I bought a DAC3. It sounds identical to the DAC1. I’m glad to have the DAC1 for a different setup, so it all works out.

Rollei 35 on Gold 200.

At least the Swedes are still doing punk.

Quite good.

Saw Mary Fahl last night, I think the 6th time I've seen her (7th if you count October Project in 1995). Wonderful concert, some of her hits, October Project hits, and covers. The whole second set was her adaptation of Pink Floyd's Dark Side Of The Moon, pretty stunning. I think this may have been my favorite show of hers. Got to chat with her and her husband after the show, and also met 3 folks with whom I'll keep in contact ongoing; just some amazingly nice people.

This is beyond cool: I have the EV-1's user manual here and it was a fascinating thing

Yes, I was just listening to Hats (1989) and I wanted to see if the band members had done anything else since then. I've been listening to A Walk Across the Rooftops a few times in the last few weeks, since I first got it in the summer. I think the Blue Nile is basically broken up. Their 3rd and 4th albums, Peace at Last and High, didn't garner the same level of critical and popular recognition, so maybe it's best to leave it at that (from the sound of Moore's last interviews about the band, it seems to be a bitter ending, at least on his part).

^^ Very cool - I have had this on the top of my queue for about a week and I have listened to it a couple of times. A Walk Across the Rooftops by The Blue Nile (1984) https://open.qobuz.com/album/hzszuzspagdab Example: An Amazing sounding Album. Some backstory if one does not know. Linn (Scottish Electronics fame) was wanting to test out their new recording console, and brought in The Blue Nile for their first release. (LKH 1) - they did well.
