Looking for 2 sets of: LSK389 LSJ109 2sc3381 2sa1349 Any tips? Scratch both... LSK380 LSJ109 ... buy matched single's from AMB.org 2SC3381 2SA1349 ... contact JohanB on diyaudio.com /V

Thx guys for the updates... Which of these LT1021 is the "right" one? http://www.digikey.se/scripts/dksearch/dksus.dll?FV=fff40027%2Cfff8013f&k=LT1021&vendor=0&mnonly=0&newproducts=0&ptm=0&fid=0&quantity=0&PV48=71&stock=1

I'm working on some pretty sweet design of a two-enclosure design via FPE/Schaeffer + Modushop Pessante. Will willingly share when it's done. However, I need some help. Any recommendations on connectors for an umbilical? Sturdy, metal etc. etc. Especially if it's available through Mouser. /V

If someone would also add the extra servo stuff on the new rev boards for the KGSSHV I would be deeply grateful.

Would you be so kind and upload an updated BOM? Thx, V

I though I'd share this. Maybe old news. German "FrontPanelExpress": http://www.schaeffer-ag.de/ They even use the same designer program.

Regarding the unpopulated parts on the new boards... Someone mind giving a newbie an explanation the differences between the different servo types and what values/tolerances they should have? Thx, V

Any tips on a novice soldering station? The ones on Mouser and Digikey start at almost 150€... Is it just me or why are they so damn expensive? I mean.. It's a warm and thin metal pen? Is this one acceptable: http://www.conrad.se/L%d6DSTATION-ST50-D-DIGITAL-50-W.htm?websale7=conrad-swe&pi=588888&ci=SHOP_AREA_17589_1508030 And a question on a multimeter that will have the range needed for measuring the KGSSHV... http://www.conrad.se/websale7/?Ctx=%7bver%2f7%2fver%7d%7bst%2f3ec%2fst%7d%7bcmd%2f0%2fcmd%7d%7bm%2fwebsale%2fm%7d%7bs%2fconrad-swe%2fs%7d%7bl%2f01-aa%2fl%7d%7bp1%2f8bf3f2d57f98b1da0791d7b63972c42b%2fp1%7d%7bmd5%2fc3eb314da460e95ef1c0e90a0859c419%2fmd5%7d&act=product&prod_index=122900&cat_index=SHOP_AREA_17622_1101010&otp1=tablink2 I'm guessing that: 0,1 mV – 600 V both ~V/-V 1 pF – 50 µF 0,1 µA – 10 A both ~C/-C 0,1 Ω – 40 MOhm is enough?

Just a quickie question... Do the different semiconductors (primarly the amplifying ones) need to be matched?

If you'd like to share it I'd appreciate it a lot!

Thx for the clarification! Let me know if you need some stiches!

Let me know which one you choose (especially if you're going to do 500V rails)

Thanks dear Nordic comrade! 1) Does it have to be 1,5 W 5%? Can't find a single one on Mouser with that spec... 2) You don't happen to have 2 LSK389 too? It's a shame ordering just 2 transistors from all over the Atlantic. /Valentin (Sweden)

I'm sourcing parts for a off-board KGSSHV... Most has gone well however unfortunately I have some questions... 2SC4686A by Toshiba, previously stocked by Mouser... Only place I found it was BDent, and at 4x the cost. Instead of 1,05USD its 4,25. Is it the same part? 2SC2705 by Toshibs, previously stocked by Mouser. Neither they, nor Bdent, not Farnell stock them. Any tips? Z4KE130A-E3 by Vishay. Can't find it stocked anywhere. Tips? Is it replaceable with this one from Digikey? CZRA5952B-G Otherwise I'm pretty much set for populating the board. Gotta start somewhere... Then worry about the case etc.. Thx!

Just a quick question... I've figured that it's the HiFi2000 Pesante case. 2U 400 mm. However, the on/off-button, pot placement and Stax-output, since both you and spritzer seem to use the same layout. Any drawings you would like to share? Thinking of using the exact same layout. Why make things more complicated than they should be.. Thx, V
