Thank you for your payments, Gentlemen!

I am still missing several money transfers, but I have already ordered the components (transistors, resistors, capacitors).

All have been on stock !

I will wait another 1-2 days for the latecomers; then I will order the PCBs as well.

I will do a revision 1 of my "FC-100 Builder's Manual" (written in my best German school-English ) and will send it to you this afternoon.

I know that one of you is already working on a BoM for the FC-100, Shunt, LSProtect and Soft-Power-On PCBs (parts being ordered from DIGIKEY).

Maybe he shares it to you all.

Best regards - Rudi_Ratlos



Best regards

The components that I ordered, are arriving.

Today: 300 pcs. of MPC74 0R1 emitter resistors.

I want to offer a "Transformer group-buy extension" to you all.

The transformers needed to power the shunt regulators of the frontend of Mihai's FC-100, are rated at 4 x 34 VAC / 50W
for 2 shunts. (In fact: 21.5mA per frontend rail is needed!)

A transformer like this can be either built by yourself (for example by "joining" a couple of small PCB transformers) or can be especially wound for you.

Several of my German FC-100 DIY-friends of group-buy round #1 and I ordered these transformers form BADEL (http://www.badel-gmbh.com):

The price of this 4 x 34 VAC / 50W transformer is about 20 (not more!).
Shipping to you (in a separate small parcel) will be:

- 8.90 within EUROPE
- 15.90 (outside of EUROPE - I am very, very sorry, but these are the prices of DHL)

The minimum quantity to order is 5 pieces.
The lead time is about 4 weeks.

Find attached the "interested party-list".
If you are interested as well: tell me please.

Best regards - Rudi_Ratlos

Could you make the transfo build for worldwide by making it dual primary 115V 50/60Hz instead of single primary 230V?

This would enable North America and more to join in as well and would make it good for 115V to 230V use.

If you can, please count me in.

Thanks
Do

Do,

BADEL will offer the transformer for both 115VAC and 230VAC mains voltage (2 primary windings).

Moreover BADEL offers several options (f.e. reduced induction - "especially for HiFi-Fans", with magnetic shield, encapsulated, ...).
I have asked a DIY-friend, which type to choose.

I have put your name into my EXCEL sheet.

Best regards - Rudi

Gentlemen,

the "last" participant of this round has paid, and I will order the PCBs tomorrow morning.
Most of you already know the procedure: the lead-time is 12 days, the shipping lasts 3-4 days, so I will have the PCBs by middle of October.

In the meantime I will prepare your letters and match the NJL-transistors.
I will send you the letters as soon as the PCBs have arrived.

Concerning the 4x34VAC / 50W BADEL-transformer:

The price of the "standard transformer" is about 21.
I would like and order the following options:

1) reduced induction - 4
2) magnetic shielding - 2,50
3) shield winding - 3

The price for the transformer will be about 31 then.

Do you agree to my choices?

Best regards - Rudi_Ratlos
