I have some of those as well, from THL audio IIRC. I don't recall any issues with them, other than the ground being a bit of a pain in the ass to solder. I'll check mine, but I've had them a few years now. They do seem to be made pretty well; not as nice as the Cardas rhodium, but a lot more reasonably priced.

Happy Birthday Colin!

Yes

Can you reverse the 2 prong and see what it is like?

Happy Birthday Steve!

How deep do you need it? The Slimline comes in up to 350mm deep. The Dissipante (w/heatsinks) comes up to 500mm deep.

Happy Birthday!

Somewhat ironic user name on that one...

I wouldn't think so, but you would need to look at the matching on them as far as hFe and possibly Vbe to determine. I would swear that some of the On Semi I've bought recently still had Fairchild markings on it (On Semi bought Fairchild). Are you talking Fairchild 06 and On Semi 56 or a mixture in the same device type(s)?

I bought a cheapie from ebay for $50 https://www.ebay.com/itm/2-in-1-Soldering-Rework-Stations-SMD-Hot-Air-Iron-Gun-Desoldering-Welder-898D/192010034886?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 Seems OK, haven't tried the iron yet (probably sucks).

Happy Birthday!

None of that shit is in yet, i was just messing around with doing the voltage switch and having AC relays in for the main transformer. I think I basically did just parallel the 2nd set of primaries with the first, with the relays after that. I realize that when switched to 240V both relay contacts are in series but as far as I could see, that is the only way to do it. Of course I could cheat and use something like a MeanWell for the relay/e24 thingie...

That looks nice John! Love the base.

Yeah, I think the fabs try to protect you from your "mistakes", when in this case it is intentional. For your one-offs, do you just do ebay or something? I've bought some machinists tools (used) from ebay with good results (Starrett auto punch, some taps, etc.).

What set of counterbore bits? I could probably use something like that myself.

Looks serious, nice copper bar. Did you do all of that metalwork? Sony eh? Very nice!

Sorry to all injured HCers, and glad you didn't get injured in the fender bender CD44hi! I guess I am at home for a week or so following a strange week and sucky weekend in the hospital. It started out with me noticing double vision when looking left. Woke up on Saturday with double vision everywhere. Went to urgent care, who ran a CT scan which showed nothing. Then to the hospital where I spent Saturday and most of Sunday. Full head MRI there, again, clean. Diagnosed as 3rd cranial nerve palsy by neurologist, confirmed by ophthalmologist today. Should take care of itself in a couple of weeks, maybe less. I guess at my age, what they find in the scans, etc. could always be bad, so counting my blessings there. Heal up HC!

What 3D package are you doing those in Justin? I was messing around trying to figure out how to do voltage switching with 2 transformers, 1 using a relay to switch on (ala Amb e24), but handling voltage switching for 120/240. Does the below schematic look feasible?

Sure, I'd be up for that.

Note that the pinout for the 2SA1349/2SC3381 does not line up with the 2SJ109/2SK389 devices, even though they are the same package. So that adapter will work for the bipolars, but not for the JFETs.

I’d looked there 2 or more years ago. I’m probably just not remembering it correctly, but it wasn’t an Adcom. Thanks for the suggestion though! Sent from my iPhone using Tapatalk

Cool, and thanks! Sent from my iPhone using Tapatalk

No. I'm pretty sure it was Apogee, but it has been awhile. I think I do (or my brother did) have an Adcom around.

cspirou: Any idea on when you might move ahead on this? Also, will the vendor provide a proto case or sample? Not sure if they do this or not. Sent from my iPhone using Tapatalk

As you may have already discerned, this board doesn't have many fans of Cavalli. That said, at least from what appears to be the Eagle board file you posted in your link, IG connects to a rather large ground plane on the top of the board (there is a 2nd ground plane for OG?). The common junction between R1L and R1R appears to also connect to IG, right by the IG pad. If you have a DVM, you could verify this. There is probably shit all over the board that is connected to this ground plane and could be used to connect IG from the pot to. And no on your screw idea... IG has to connect to the board as reference for the input section.
