Happy Birthday Ari!

BL if you can get them (same for 2SK170). Is Amb out of Dynalo boards? I may have one laying about that I probably won't need (the original DGardner boards, not the ones Lil Knight had run). Stock Dynalo gain should be fine; I've never adjusted the gain on any of mine and they have been just right for all the phones I've thrown at them. Note, I didn't look at your schematic from work.

Happy Birthday!

Have a great time Gene! Beach and water look great!

Glad you're OK Bryan!

Really like these guys (and gals)...

x N. Really sorry to hear about your respective fathers. Archosman, gald you are able to be there with your dad.

Maybe... never heard a DynaFET

Your added observations could just point to one key difference between the Beta22 and the Dynahi/lo... FET vs. BJT output stages.

I had used the plain old GE Silicone II in clear before. Many of the caps in the Counterpoint pre I used to have were affixed using clear silicone (from the factory). As long as it is low odor it should be non-acidic. From a quick google of electronics-grade silicone, it looks like GC has one for a reasonable price (<$5 a tube).

Happy Birthday Kevin!

JAE makes some pretty decent ones as well (SRCN series), more affordable than the Amphenol mil-spec ones, but work well. I used these on the Sigma22 I built for Jim for his Audio Alchemy amp. I think they are rated for 300Vdc. The Counterpoint preamp I had used these on the umbilical. Running ~430Vdc through it http://www.mouser.co...ord=jae&FS=True Digikey carries these as well. I hadn't seen the Switchcraft EN3 series that Marc recommended. Those look nice.

THat guy is full of it: SOME IMPORTANT HISTORY: High-end audio was nearly non-existent in the 1970s short of a few companies like McIntosh and even those marketed their gear around objective criteria. If anyone tried to sell a $2000 power cord in 1980 they would have been laughed out of business but now there are dozens of companies selling them. Really? 1970s (early) How about Marantz, KLH, Infinity, SAE, etc.? Many more later in the decade. He probably has a point in the 2nd sentence... MAGIC: Some compare the supposedly better sound heard from high-end gear to “magic”. Lieven quotes Nelson Pass claiming “It is nevertheless possible to have a product that measures well but doesn’t sound so good. It is still a mystery as to how this could be.” In effect Pass appears to be saying amplifier sound is mystical. But it’s not. Lots of credible published research demonstrates measurements predict sound quality. If Pass is so confident measurements don’t tell the whole story, where’s his published blind listening test demonstrating his view? Such a result would certainly help sell more of his five figure products so he has a strong incentive to publish such a test. Still, magic is an interesting analogy. Magicians know how to exploit weaknesses in our senses to deceive us. Convincing someone a $2000 power cord really sounds better is a similar act of sensory deception. Claiming Nelson Pass relies on mysticism? Heh, good one.

^ this ^ and this. How many words did he take for the O2 amp? One each shit ton from what I have seen. I would really like it if he started picking on established commercial makers (like RSA) rather than Ti, etc. Just because they haven't plunked down on a dScope or equivalent doesn't really mean shit. He can rant all he wants to about RMAA, but used properly, it isn't worthless.

I bought a Delta 10" tabletop drill press at Lowes a few years ago, but they don't make that model any more. It's runout, etc. is fine for doing even PCB holes to #70 or so. That said, I'd heed Dr. Wood's advice...

shit!! that's good it wasn't a stroke Reks! Hope you get feeling better.

Is this the lil'knight GB board, or a new one?

Was going to comment on that a couple of pages back Fitz... looks like fun Good luck!

Happy Birthday!

Same here...

RIP!
