Good NOS (heh) 6922s are probably rare as hell anymore. When I used to have a tube preamp (Counterpoint SA5.1) 10 years ago, I had a pair of Amperex PQ white label 6922s in it, which I really liked. The EH 6922 gold pins are quite good. If you can manage to find some vintage, you will pay out the nose for them, and possibly get ripped off. Some seemingly decent recommendations for dealers here: https://www.thegearpage.net/board/index.php?threads/online-tube-dealer-sticky.1197164/

Another pot or stepped attenuator I have worked with (on Todd's CFP3) is a 41 step unit from Acoustic Dimension. It seemed pretty nice with good tracking, etc. The do make quad units, and the one in the CFP3 was a 10K, which they don't show on their website. http://www.acoustic-dimension.com/

Oops, sorry. No, I got the unit in fine shape. I like it very much! That said, I don't use it a lot as I haven't been playing DVDs/Blurays much lately.

Sorry, don't know where to find either, but in general, for any of the designs using old silicon, it is a good idea to source all of the silicon, or at least make sure you can, before investing in PCBs, etc.

A 14+ year necro thread... not an auspicious first post.

Haven't looked at the schematic, but 30V secondary would produce 30 * 1.414 = 42.4 V raw DC, less the rectifier drop (1.4V for full wave). So if the caps are right across that, 25V isn't going to live long. Looked at the schematic, and the caps are right across the secondaries after the bridge. A 30-0-30 seems rather excessive for a +/- 12V supply. 15-0-15 would have been a better choice.

Sorry for your loss Todd.

Yeah, I had heard some negatives regarding him (and his thumbprint on the show) before the series started, but went ahead and watched it anyhow. I can't say I've been a big fan of his (watched Dollhouse, but never really watched much of his other stuff). Apparently he isn't involved with the show since the first few episodes.

Hmm, the datasheet right off of Genesic's site shows GDS: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwi5usK-kvnwAhXKZs0KHYmTCvMQFjABegQIAxAD&url=https%3A%2F%2Fwww.genesicsemi.com%2Fsic-mosfet%2FG3R450MT17D%2FG3R450MT17D.pdf&usg=AOvVaw1sVqBXJV-AnV_PZztKUbPF Now this is confidence inspiring! Newark's is GDS Arrow's is GSD

Has anyone been watching "The Nevers" on HBO? I have, and while it has many problems and is kind of a mess, have been enjoying it. Joss Whedon, who I know has a lot of fans here.

When you say "then I replaced all the internal cables with 2.5 mm section OFC. I didn't think the sound changed so much for the better, I don't recognize them anymore." do you mean you like them better, or they sound worse? And yes, pictures or it didn't happen.

I'm watching it as well and like it.

Happy Birthday Brent!

Deftones-White Pony I'd always like the song Change when I would hear it on the radio, but had never bought one of their albums. My oldest son had played Beauty School off a later album for me, so I requested both of these as CDs for my birthday. I listened to Change last night on the speakers and was astounded at how good it sounded. I really wish some of the stuff I really like from the early-mid '90s had been recorded and mastered this well.

Thanks guys. Yes, I use the 5.08mm SPOX connectors on my own (lower voltage) builds, as I detest the screw down connectors for my own use. I'll need to take a closer look at these, but Molex makes a Micro-Fit 3.0 series, which is 3mm pitch, and rated for 600V apparently. 3 pin PN: 43650-0315. Might be something to plan for on PCB designs if they actually work out to their ratings. I have some of them for some Salas shunts for a UGS preamp project.
-
Any part numbers for these? Any search I do on Mouser brings up a TE Mate-N-Lok, and isn't 5.08mm pitch..

Thanks all! I had a nice quiet day for the most part. No listening, but some imbibing did occur...
