Hi brncao, Check Lil Knight's site http://tee8tee4388.blogspot.tw/2013/07/kgsshv-amplifier.html

The board's color also caught my eyes. Well done! Thanks Kerry!

Finally received my power transformer, I can keep working on. It's [email protected] x2 and 16V@1A x2 , order from a local PT factory.

Congrats the problem solved!

Doc, many thanks!

Just wonder if Kerry may make them tighter, and put them in chassis like densen's amp will looking cool .

Dear Tran, Need remove 270V zener if with 2SA1486/2SC3840? Thanks! Pal
-
Tran told: ksc5026 and ksa1156, instead of the 2sc3840 and 2sa1486. There's more parts need for mini PSU. 2x 2K resistor, 2x 270V zener, 2x 24V zener. (You may check schematic and pcb, Dr.Gilmore has posted them.) +/- 15V capacitors size has been changed. 2x 3300uF and 2x 330uF, dimeter/pitch are 16mm/7.5mm and 10mm/3.5mm. 78/7915 don't need heatsink.

Sato is nice, my friend helped me got some parts from them. I've found another keisei-net co jp , they provide oversea shipping. But I didn't buy from them. Can check stock online.

Hi Tran, Thanks for your explain, now is clear questions to input numbers in spreadsheet. Thank you very much! Pal
-
Hi Tran, Questions about notes in spreadsheet. Squarewave = KSA5 PSU + Amp Is that means "One set" include 1 x PSU and 2 x amp PCB? Dynahi onboard = 2x New amp board ONLY. No PSU. "One set" include 2 x amp PCB for balanced setting? Thanks! Pal

Like this wood knob!
