Endured more power outages, but, thankfully, without a side of u contained wildfire. Noticed that the local cell tower went dark ~4hours after the power, so that's it's battery backup gone, I guess. This morning we went looking for hot Coffee and a 4G signal with internet connectivity (not a given). I am reliably informed that in the first world nations of The East Bay, and The City, they have both and Electricity! We eventually got lucky at our local Solar Powered supermarket to the Bourgeoisie. Power, Speciality Coffee and Queues. Later got an internet connection just in time to intercept the weekly call with my mum. Which was nice. Currently parked on elevated terrain with comms to the outside world, fast charging the nerd phones from the car. Apparently this situation is on again, off again for the next week (and structurally for the next decade if PG&E are to be believed) Fun Times! EDIT: curiously , spam calls, ads and emails are still getting through!7 points

I'll certainly share them. I can't quite tell if I've got a persistent z-axis issue or not. It seems to do some weird things every once in a while where it plunges to a different depth than it finishes but I haven't really taken the proper time to troubleshoot it. It's essentially doing what I ask if it right now but there's no freakin' way that it could do metal as-configured. The z-axis is not rigid enough and can't develop enough down pressure to hold position. I think the first upgrade I'm likely to make is the HDZ option. Today's handiwork, which Andrew requested so that we could have a gravestone outside for Thursday. It's pretty fun to be able to whip something up like this and have it cut out in less than an hour.4 points

I haven't tried a new one in a few years but I might pickup a fresh set just to try out. Speaking of the 007's just see what Stax dropped on Youtube...3 points

Still no power this morning. It’s been out since 7pm Saturday. Word is now that it might be out until Thursday. This is insane. It might be time to head out of town for a few days and get a hotel room somewhere else.1 point

I recently have been slowly acquiring modular synthesizer parts and stuff. I have nothing to present yet as it still sounds rather flat to me (need more gear) but the hobby seemed like the natural progression of being in this hobby and being a DIYer.1 point

Well, by accident I found Head-Case and “The ultimate DIY? A Stax SRM-T2!” on internet in 2011. Read that thread back and forth several times and I became kind of absorbed by the clone Stax T2. So it’s actually you Craig and Kevin, Birgir, Kerry, INU, et. al. that dragged me into this – I’m very grateful for what you all did to get the DIY T2 possible for armatures like me to build. After managing to build a KGSShv successfully I felt ready for the real thing - DIY T2. Bought boards from Tran and I actually succeeded with this monstrous project and had a working amplifier - at least for a while. Then all kind of problem popped up. Somehow I did fix them but eventually I found it meaningless to continue with that amplifier. Reason for the problems was probably myself (Builder Induced Failure) but it gave me a lot practice. My impression was that the quality of the boards Tran sent me was a the lower end. So I order five high quality amplifier boards. Desolder all the expensive sands including c3381 and used them on a new board. Believe it or not but it succeeded despite reused sands - no popping up failures. Then I started to make some modifications (don’t ask me why – just a bad habit) most of them worked. As I thought I needed an unmodified as reference I built the third T2. Now it felt like - just put the right component in the right position, power on, adjust batteries and you are set. But of course I started to fiddle with the new one as well. After a long hike with my wife this summer. 820 km/ 510 miles in 31 days I felt it is most appropriate to have an original DIY T2 again (I still had three amp boards left). That’s why four.1 point

so the 700s power supply voltages are exactly the same as the 717 and 727 from the transformer yellow,green,yellow go to full wave bridge rectified and regulated to +/-15 blue black blue (the filament supplies on the 700t) rectified and added to Vh- to make the - boost supply white red and brown orange are the 2 high voltage windings full wave rectified into CRC making +/-350 output boards identical to the t8000 each board has 3 x 2sc6127 and 1 resistor vas boards have 4 x 2sc6127 (2 x Darlington pair) and 4 x 150k/2W current source (on main board) vas is driven from dual low voltage n-channel jfet. (red heat shrink) (previously dual npn transistors) front end identical to 717/727 with dual n-channel jfet so about 99% identical to srm717 with non-obsolete parts and change of vas stage driver from bipolar to jfet on the D50 the front end jfet is known to be sourced by linear systems. So likely the k170 are also sourced by linear systems. so the 700T absolutely identical in every way to the srm-007t (and srm-t1 etc) with 2 x 6sn7 replacing 4 x 6cg7 plenty of room for replacement constant current sources to replace the mills load resistors both are priced the same, between $2895 and $29951 point

Removed a dead possum from my garage. I have a detached garage that I only go in every once and a while. Looked like a possum got in there and couldn't get out.1 point

For an inexpensive alternative, you could get an old SRM-T1, then for around $100, replace all the old electrolytic capacitors and put in my CCS mod. For another $100 substitute a TKD pot for the Alps, although you lose the balance function. Won't sound as good as the KG alternatives, but will sound better than any standard Stax amp IMHO.1 point
