The cat, obviously!

Stunning is right! Nice job boyz!!!

Gawd, you made my ears cringe with that... I think my '70 Chevelle SS had one in it. Never bought any 8 tracks, but played one in it once. Almost threw it out the window! Man were those things bad.

R4 and R6 are crooked... tsk tsk.. EDIT: j/k BTW, they look great!

Happy Birthday!

Happy Birthday Ari!

Happy Birthday Shelly!

Pretty cool video of a couple of endurance cyclists doing a 467km stage from the 1903 Tour de France on near period bikes. https://www.globalcyclingnetwork.com/video/can-we-ride-and-survive-a-stage-of-the-1903-tour-de-france

Tried a recipe from a restaurant, Pastabilities, in Syracuse, NY as seen on DIners, Drive-Ins and Dives, called Wicked Chicken Riggies. Basically chicken and rigatoni in a spicy tomato cream sauce. Quite good and the whole family enjoyed it. I'll be doing it again. The recipe makes a huge portion of the sauce; I cut it in half and still have enough for another meal for 4. Sorry, I'd already started eating before I took the pic

You normally just upload the .zip, not the individual files. I don't use PCBWay and didn't want to go thru their registration bullshit, but tried the file with seeedstudio and it worked fine. The Gerber viewer picked it up just fine, and it didn't look like it would be any problem.

So I guess that GRLV board I sent Justin went to good use

I would hope this would give the climate deniers a pause for thought...

Never cased it.

We've gotten snow here in Chicago area twice this week (including Thursday night). I can deal with this kind of snow: a) don't have to go anywhere, and b) it doesn't stick to sidewalks and driveways, so don't have to do a damn thing about it

I think you'll like this once completed!

Not necessarily. First, it sounds like you are trying to measure these at too low of current. Look at the datasheet. The min hFe for the MJF15030/15031 is 40mA. They should ideally be matched at about the current they are going to run at, if possible,

One could ask why you are building a hi-powered amp for an easy to drive phone? Maybe an SS Dynalo would have been a better choice?

Interesting. Where you have the temp probe was always the hottest area when I was using an IR gun. Maybe a bit further left. Any reason you didn't populate the rail caps (above the right heatsink)?

I don't think you're going to get any closer than that

Sorry, just seeing this now. Not sure, but that sounds about right. See attached for the BOM I have for each. In the GRLV BOM, ignore the Schottky rectifiers (yellow shading). I only see an R21 500R resistor feeding the + input of the - rail opamp on the GRLV. All of the pots are labeled RV# in the schematic that I have. goldenreference LV schematic.pdf GR HV BOM_Sep26.xlsx Steve, I hadn't read that regarding a 4.5 digit DMM, but I would assume you would be able to see something? I've never used the trimpots for adjusting the voltages (I usually use either matched resistors using my HP bench meter, or 0.1% resistors and live with the results.) GR LV BOM_Sep26.xls

I took it as room treatment, as that is what Michael does (did?).
