Op-amps: the makeup stage is my cascode DOA, 2sk170 for input, rest PN2484/4249/BD139/40;
Input stage opamp is Quad Eight AM-4, simple and easy thing with great sound.
"Original" Helios amp relayed for 24V power supply (51X or rack, will not run in 500 lunchbox) is on the way too.
500 version can run at +/-16 with API style DOA's.
For more coolness, 51X or rack version with +/-24V is recommended.
Tony, don't sell the kidney, we still need you for Sontec pot's groupbuy!
BTW, few days ago heard the paranoidal story about Red Cross,
kinda, it is private organization and they selling the captured (prisoners as google translator says) for the spare parts.
I like these stories in Zeitergeist style, infinite stupidity, a great source of amusement.
Until aliens came from another galaxy and captured me with their anal probes (hey, it is almost 2012!!!)
The final, fixed, nice batch of 500 and rack Helios PCB's, 30 ea, is on the way here.
Docs, BOM, support thread - within few days.
When I have PCB's in hand, they will pop-up in my store... Stay tuned!
Ah yes, aliens again. Thought about those aliens and absolutely forgot.
Fronts!!!!
Ordered 100 of nice black brushed anodize blank fronts, laser cut,
same Shifram Israely factory where my 51X racks were manufactured.
Precision guys, they do cases for all North Israel electronics industry, including Elbit and Rafael.
The fronts will be here at next week.
Alu 6061 material, great for CNC machining, all I have to do is engrave and mill holes.
Bracket+mounting hardware+front price should be in range $85.
PCB price should be in range $65 either rack or 500 version for mono set.
Inductors: Carnhills should fit, however, I not checked.
Pair of locally made inductors should be in range $42.
