I received the boards yesterday.
Impressive job, very well done!
Thanks for your great work

find out that some parts are missing in the BoM:
LS-Protect
1x BC 517 ist missing (need 1 per PCB)
FC-100 AMP
only 4x 2,2R are included you need 6x 2,2R per PCB
MKS-4 100N -> need 2 per PCB only 1 ist included
The Spacing of MKH100-15 470N is 15 mm does'n't fit to the PCB-Spacing
Shunt Regulator
missing the 2x 2,2nF and the 2x 2,2µF Caps included are 2x MKH400-7,5 4,7N ??
maby Rudi can explain what todo with the 4,7N 🙂

Nico,
LSProtect: instead of the BC517 you can take a 2N5551, BC546 / BC550, ... as well.
FC-AMP: you need of course 6 base-stoppers 2R2. You need 2 MKS4 - 100nF.
I cannot find the 470nF that you are talking about.
Shunt-Regulator: REICHELT does not offer 2.2µF MKT capacitors. These capacitors are "bypassed" by ceramic NPO capacitors.
I remember that REICHELT did not offer 2n2 at the time, when I added this cart. That is why I included 4n7. The 4n7 will do it as well.
Best regards - Rudi-Ratlos
P.S. It is not possible to change a public cart. The only way to change things is to delete the old cart and add a new one
(with corrections made). But then the URL I sent to you all is no longer valid.

OK thanks Rudi
i talking about this one: MKH100-15 470N - capacitor 470N, 100V at reichelt elektronik its in the cart of Shunt Regulator.

Hi Rudi!
I got the package from the post office today. 🙂
Thank you again for the effort you put on this GB.

I could be interested to take the following items:
FC-100 pcb - 2 pcs
Shunt reg. - 2 pcs
Futaba resistor - 12 pcs
Matched JFET - 2+2 pcs
Can you give me a price with shipping included?
Thank you.
Anto,
I have 2 FC-100 AMP PCBs left.
I do not have any other PCBs, for example: I do not have the shunt-PCBs, but you can start
with a LM317 / LM337 voltage regulator for the frontend.
The frontend needs +/- 37VDC @21.5mA.
If you are interested, I will check, if I have any other "hard-to-get" components for you.
Send me a PM.

Group-buy Round 2
Gentlemen,
after having received several requests concerning the build of Mihai Rauta's FC-100, I feel obliged to open Round 2 of a group-buy for this amplifier.
I will once more not only provide you the PCBs, but will assist you in getting the "hard-to-get" components, like: NJL0 - transistors
(I will match them for you), MPC74-emitter resistors, authentic Toshiba 2SA / 2SC transistors, matched input 2SK170 transistors, ...
Since I have promised my German DIY-friends to offer them a project for the long autumn and winter evenings, I will align Round 2
with my offer to my German friends.
Do therefore not expect this round to be closed before October.
In my ears Mihai Rauta's FC-100 defines the "TOP" of what can be made by DIYers.
Find attached the interested part list.

Hi Rudi,could I get the following.Fc100 pcbx2.Shunt pcbx2.Ls protectx2.Soft startx2.Total so far Euro74.Output transistor setsx2 and other "hard to get "trannys if possible and the total cost.Thanks and best regards,Manuel
Hi, Rudi. I think I would like to have a go at this amp too over the winter. Can you put me down for 2 of everything for now until you decide final cost for all. Thanks again for your hard work for DIYers!
