My condolences to you and your family, HS

Thanks for all the discussion! I'm getting ready to case the DynaFet up and am trying to determine how I want to switch the power. A 2 switch approach (one on the inlet, and a ring LED vandal type switch on the front) appeals to me. A plus would be not having to run line AC to the front. I'm using a 2U Pesante Dissipante 300mm (from the age old group buy), so have plenty of room. Voltage selection would be a plus, though not required. Are many of you still using SS relay to switch the AC? I'm looking at the Amb board, and I guess might need a 2nd xfrmr, turned on by the back panel switch, to then switch the main xfrmr AC?

Went back and looked at this again; a lot to like here! Neat power inlet... some kind of Schaffner inlet? EDIT: nope, Schurter (found it).

Happy Birthday Doug!

I assume these cases are from China? Any hint as to who/where they are from? Everytime I see one of your pics, I keep thinking I like those...

did a search on "printing 1st class labels" or something like that which brought me to this page: https://www.etsy.com/teams/7722/discussions/discuss/10736601/ Luck I guess. I always liked Paypal shipping, and had forgotten about it.

Happy Birthday Duggeh!

just watch the gauge... not sure Home Depot carries the ones that do up to 30ga.

A lot of people use navships wire in their projects, though I haven't used the particular one you have. I use 24ga hookup wire from navships, as well as 18 or 20ga for power. Teflon jacketed (big plus).

Can't remember who posted the original BOM, don't think it was you. The Wima are pretty much the only ones that large cap in that small of footprint. Sent from my iPhone using Tapatalk

I'm curious why the BOMs I see show Elna Silmic caps for the 220uf caps on the PSU? Usually audio grade caps are spec'd for coupling caps (Pass seems to like them), but for a PSU? Some reason that I am missing? I used Pana FM/FR for the ones I built. Sent from my iPhone using Tapatalk Sent from my iPhone using Tapatalk

Probably should ask this in the GRLV thread, but I'm curious why the BOMs I see show Elna Silmic caps for the 220uf caps on the PSU?

Is it one of the Bulgin MP0045 switches? Latching? I need to get one, or something like it. I know Birgir was using switches from one of the PC modding places, frozenCPU. Sent from my iPhone using Tapatalk

Just had to try it to see if I remembered... NoNoNoNoNoNo And no way in hell that is filburt's doing. Sent from my iPhone using Tapatalk

or risk overheating the ban hammer

Same here. Single sided sandwiched with double sided blanks? I'll give you an A for creativity! I personally will stop at 2-layer, and commercial houses are so cheap anymore I don't bother with those

Would any of those handle enough current? Sent from my iPhone using Tapatalk

Ahhh, makes sense now. Carry on

Looks really good. I like the case(s)... custom? Or off the shelf? Nice clean look.

A couple of things: A torroid transformer doesn't put out DC... it is AC Those SOIC adapters will be a nightmare if the opamps you replace the existing with are fast at all. What opamps are you replacing and why do you think they need to be replaced? FOTM?

What positive comments?

I don't think we got more than 2", if that, further west in Chicago burbs. Partly sunny and not snowing out here (right now). Robins are wondering where they fucked up, however
