Happy birthday Viking Baker! Cheers! :Dan:

Happy 36th birthday Birgir. Mellowing like a good wine....... btw.... I have heamorrhoids older than that........

My favorite rum drinks: rum w/ lime juice, symple syrup and cinnamon rum w/ pineapple/orange juice and cherry bitters rum (in all cases, Smith & Cross or Goslings Gold)

Have a fantastic day Greg! Do something different today, like drinking some good wine and buying some foils!

Another electrostat CFA lives. This one born on the 4th of July? The PCB is congo5's layout. The amps is powered by my GRHV PSU with ~405VDC rails. Many thanks to Kevin for another wonderful design, to congo5 for the PCB boards and many advices along the way and to sorenb for his generosity of coming to my rescue and providing the missing, unobtanium sands. This build would not have been possible otherwise. I did not match any of the transistors - barely had enough for this one build. The output balance of the two channels sit at 6.6VDC and 4.4VDC after one hour running. The offset is 10.7/4.2VDC and 9.7/5.3VDC. For both channels, the non-inverted output offset is the higher one. The heatsinks are at a toasty 52C after one hour running, about 28C rise from the cold start. Will need to find a chassis with larger heatsinks.

Documentation? heh Which amp? This is a confusing thread because there are at least 3 amps discussed here, maybe more (Kevin or others, correct me if I am wrong): CFA2 (CFP) - current feedback amp. Each board does 1 channel SE, so 2 for stereo SE, 4 for stereo balanced. Kevin later did a mod to this adding current mirrors feeding the servo. People who had built the original noticed that the servo was audible as to quality of opamp. The schematic in Kevin's archive is the older version. CFA3 - current feedback amp for balanced. Not sure if anyone ran boards for this one. Basically a pair of CFA2 amps and ubal-bal board on one pcb. Schematic does not show the current mirror mod as in 1 above uberamp - seems to be a power amp; I've never quite figured this one out Here are the schematics for the CFA2 (current mirror version), and the CFA3. I also attached my BOM for a CFA2. Amp quantity shown is for stereo SE. If going balanced, double it. It should reflect the later current mirror version. You'll also need some GRLVs or other power supplies, etc. cfa2cmirror.pdf cfa3production.PDF CFP2_BOM_update2018march.xlsx EDIT: I also ran across another schematic on Kevin's site which I hadn't seen before: currentsourceamp2.PDF. This seems very similar to the cfa2cmirror schematic, but is described as a transconductance amp.

Thanks for the BD wishes! No foils broken so far and fingers crossed. Did I mention it rains a lot hear and it is humid as a Louisiana swamp in July? ?

afternoon foo.. The Foo Fighters' - 2014 - "Sonic Highways"

So yesterday I had to go to Home Depot in Colma (the burbs), and passed a Sizzler restaurant. I didn't even know they were still around! Last time I ate at Sizzler was when I was 17, and my buddy worked there (so naturally he fed me for free). I thought what the hell, pulled in and saw that Malibu Chicken had survived their menu for the last 40 years, so that's what I ordered. The young man informed me that if I was 55 or older I could get the senior plate of said Malibu Chicken. "As a matter of fact" says I... So for a paltry $11.00 I had said Chicken, baked potato, Texas toast and a large salad. That also included the soda fountain. Better than memory, and I left full and happy. Waiter's eyes gleamed at my $5 tip. Oh the simple things!

Thanks for the condolences everyone. Xavier and I are back on the trails, though. Went out for a father's day ride. Sent from my LG-H932 using Tapatalk
