July 8, 20196 yr Author I owe everyone a long past-due update. Long story short, I injured my right hand in early April right around the time we set out to test the final boards before sending the Gerber files for estimates. Actually got parts ordered and delivered but I was way too optimistic with the recovery schedule of my hand and I am finally to the point I think I can handle a soldering iron. I am back in touch with Kerry to sort out a few things needed for testing. Apologize for the lack of communication for weeks. Hopefully we will be back on track with the GB soon!

July 8, 20196 yr Taking the time to get well is the #1 priority. All else is just a DIY hobby. Don't push it. Get your health back first.

I know all about underestimating recovery time tables. I had major ankle surgery in February and I'm still on crutches lol
July 9, 20196 yr Take care of yourself first! This is just a hobby, no rush. Wish for your quick and complete recovering!
July 10, 20196 yr Yes, get well Michael! You'll get back to it sooner or later, and no one expects you to do the prototyping until you feel up to it.
July 10, 20196 yr But Michael you have two hands... use the other one!!! ... best of luck getting 100% better!
July 28, 20196 yr Author Quick update of status; Some changes are needed for the GR78xx and GR79xx boards. Working with Kerry to get new boards fabricated for testing. Good news is, with the delay, a couple of parts that were out of stock everywhere in April are now back in stock so we don't have to settle with substitution parts for testing.

September 30, 20196 yr Depending upon the price, I would be interested in 2x GRLV78xx and 2x GRLV79xx Thank you.
October 1, 20196 yr Just finished designing the GRHV79xxx, which is the negative rail. I'm going to order some boards and test it out as well. Maybe add this to the group buy if it works On the testing front I'm done test the GRHV78xxx. I've made one small change to the board and will test that as well, but looks good. The GR78xx-Micro looks good and will test the GR79xx-Micro shortly. Michael is making some progress as well and I hope we can get this moving sooner rather than later PS I'm happy using the 7V reference. It requires less current which reduces heat and works well.

October 2, 20196 yr Please add me for 1 set of mini T2(2,1,1,1,1) Edited October 2, 20196 yr by mumford x
October 2, 20196 yr Author Quantity of 1 for the mini T2 represents a pair of left and right channel boards.

October 15, 20196 yr Just got a few boards in. From left to right... GRHV78xxx, GRHV79xxx and to the right is a new experimental digital alternator. It’s stackable for balanced
October 15, 20196 yr Briliant! Damn excited by the perspective of those miniature HV supplies. You are never short of wonders Kerry, are you? One day I'll have to study those relay attenuators. The coding (which you provided) and Arduino thing have always seemed too complicated for me ? Edited October 15, 20196 yr by G600
October 15, 20196 yr Is it too late? Please sign me up for: 2x GRHVxxx1x GRLV79xx1x GRLV78xx1x Main Board 1x miniT2 Edited October 15, 20196 yr by lkong
October 16, 20196 yr They look very good Kerry!!!. What size SMD are you using? it looks relatively small. The same thing happens to me with the "digital" theme. I see it too complicated and I need a lot of help (more than usual)
October 16, 20196 yr The resistors on the digital attenuator are 1206. For the HV supplies the resistors are a mix of 1206 and 0805.
