I think I have some, will look tonight.

Happy Birthday!!!

KG had this to say in one post: http://www.head-case.org/forums/headphone-amplification/1296-corda-opera-post30900.html?highlight=ground+channel#post30900 I've never compared the same amp in a 2 channel vs. 3 channel variety, so can't say.

Happy Birthday!!!

Pics show up for me just fine... congrats!

Yeah, that would probably work. I would prefer a button with a shoulder on it, but if the buttons fit the switches well (as in tight), etc. those would be good. One thing that can help alot, particularly if you are going to be attaching PCBs to a front panel, is to back the front panel with a piece of clear plexiglass. I don't know how thick you were planning your front panel to be however.

I really don't know since I've never used tactile switches and never done anything like this. Check Bergran's CD player out as he used 8 of them. I thought he had pics of the buttons he machined but I couldn't find them: Bergrans CD-Pro2M controller

I think it is kind of a blind bore, or like one, where the hole from the rear is larger than the hole in front and "stepped" somewhere within the thickness of the panel. I know the FPE designer lets you do stuff like that. Figuring out what dimensions, etc. to use is another thing.

FTFY

You might also check to ensure that your intended XLR cables can fit that close together... probably not a problem for XLRs, but with some of these guys building garden hoses...

Very nice! The XLRs are a bit tight together, but I suppose to fit everything in they need to be. I'd like a bit more material left between them if it were me.

You just needed Carlo (IIRC?) to mod it for you...

You already know the answer to that... as Grawk reminded you.

Phono cartridges will do that... even then, you wonder whether its REALLY right...

How about 2%? Digikey has the BC 416 series (Morsel likes these alot) BC2068-ND for the 0.047uf

No, it was one while I was starting to / in process of doing it, and people were recommending programs. I could of sworn it was here on head-case as I would have a higher degree of trust in the answers than on other sites.

Thanks, but I got it working fine. I thought this thread had more discussion on doing it and mentioned 2-3-4 or more programs... must have been elsewhere?

Marc, Does that mean you have some of the duals, or some 2SA970 / 2SC2240s? Thanks Pete, I'll send you a pm. Chris

Anyone have a pointer to pics of a Tektronix scope that is done point to point? I've always heard that if you want to do pt-pt right, do it like that... and a scope is a hell of a lot more complex than an amp.

I've got quite a few as I use these for I/V stages. These appear to be lower noise than the duals are? Kevin commented on the DynaFET thread on headwize that these could be substituted with the 2SA1145 / 2SC2705s that are already used elsewhere in the Dynahi, but might be noisier. The 2SA970 / 2SC2240s would seem like they might be a better device for this...

I was going thru my stash to see if I had enough to build a Dynamight and found that I'm short a pair of each of these. I then found that they aren't available anymore Does anyone have (2) of each they would sell, or barring that, anyone know what the singles of these are (if there is such an animal)? If not, would something like matched pairs of 2SA970 / 2SC2240s work?

Hope you had a good one!

Particularly when it is on... <<<shudder>>>

It seems odd that if, in Mikhail's mind, there are issues needing resolution before he can ship Elephas' amps, that he would be actively trying to contact Elephas. Sounds like he is ignoring Elephas' attempts at contacting him. Something doesn't add up...
