Would you be able to run Windows IE on your Mac using Wine or WineBottler? I've used this on mine to run the Windows versions of LTSpice and DipTrace. It seems to work pretty well. https://winebottler.kronenberg.org/

No shit... coding for IE? what a piece of fail.

B normally... the equivalent of the Toshiba BL grade.

Happy Birthday Al!

Good god! Those things are almost approaching what where they, K1000 AKG silliness in their looks (from the front)! Back in the '70s, my brothers and I were looking for a set of speakers and the Heil AMT-1s were the runner up (to the Infinity Monitors with the Walsh tweeters). We used a single recording for evaluation... the 1970 or so CSO/Solti Mahler 8. It wound up that we would buy the speaker that didn't break up playing it at a good* volume. The Bose 901's sadly didn't make that cut... * i.e., loud

I know that Kuei Yang Wang (Thorsten Loesch) one of the principals of Abbingdon Music Research really liked the Campfire Andromedas. He modded a set of KZ ZS6s to try to mimic them, but was given a pair of the real thing. I'd like to listen to them sometime. I modded a set of the KZs as he did, but didn't like the sound (but they did sound a lot better than stock).

Happy Birthday!

I ordered one of the microscopes that you recommended Jose. It says mid-April for delivery

Since I don't have a laptop (other than my work one) readily available, or a computer down in my workshop, I'm wondering if something like these might work better for me? https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=600X-8-LED-USB-Portable-Digital-Microscope-4-3-LCD-Screen-Tool-Zoom&_sacat=12576&LH_TitleDesc=0&_osacat=12576&_odkw=8-LED-USB-Portable-Digital-Microscope-4-3-LCD-Screen-Tool-Zoom

Damn, I might have to get something like that. I was trying to touch up a 100 pin uProcessor and am having a hard time telling what I am doing with my Optivisor. Sent from my iPhone using Tapatalk

I used KOA Speer 1/2W on everything I could. The 121R are Vishay/BC MRS25 (0.6W, 350V). I’ll either get some RN60 or Xicon 1/2W for the 174K. Sent from my iPhone using Tapatalk

Those were what was on the BOM. I’ll get some 1/2W, though I think people have built from this BOM before? Is a 350V rated part sufficient? Thanks! Sent from my iPhone using Tapatalk

Happy Birthday Nate!

Thanks Michael. Yes, I was going to get some heatsinks something like you used to bolt the angles to (as well as the PSU angles). And thanks for the tip awhile back about putting standoffs upside down for mounting the resistors, etc. to get them spaced off the board. Worked pretty well! They aren't perfect, but pretty good I think.

A pair of Carbon boards complete other than JFETs. I used Soren's pre-adjustment method on the CCS's. They all came up at 15mA initially; adjusted them to 17mA for a start. I still need to clean the boards more. These are the .6G boards and appear to have a ground plane (haven't looked at the gerbers), so all resistors, etc. are up off the board. If any of you Stax mafia dudes see anything amiss, please let me know. I was careful building these... Also, I got some pluggable connectors, Hirose DF5A (DF5A-5P-5DSA(35), DF5A-5S-5C) which are 500Vdc rated, and would fit just fine. They have one small nub or pin on the bottom, but it looks like you could either cut it off, or drill a small hole in the PCB for it.

Happy Birthday Craig! Hope you have a great one! Sent from my iPhone using Tapatalk

Thanks guys. The video was interesting, to say the least

Does anyone have schematics for either the Gold (balanced?) or the unbalanced version of these? I told a person I dealt with (diyaudio user) that I thought they might be available (and told him why bother), but his interest is just in the front end section as a preamp). I saw what is available on the eservice info site, but can't remember my login there. The user says he has some incomplete schematics with pencil markings on them. I had the attached jpeg, but think this could be what he already has. Thanks for anything you can find.

Kinda what I was guessing. Thanks Kevin! Sent from my iPhone using Tapatalk

Happy belated Birthday Naaman! Sent from my iPhone using Tapatalk

Thanks Michael. Actually, I was referring to the pairs of holes for the 10M90s I believe on the Carbon boards themselves (top of pic, past the two resistors).

FTFY

Stupid question time, but what is the purpose of the stacked holes for the HV part mounting? Not the best pic, but best I could find.

I’ve been presented with the possibility of acquiring a Pro-ject RPM 5.1. Anyone know anything about these? My current table (which I haven’t used in years) is a Thorens TD-320. Any thoughts appreciated. Sent from my iPhone using Tapatalk
