Roender's FC-100 Rev.1 Group-Buy

[Rudi_Ratlos]

Gentlemen,

we are exactly in time.
This is the message that I received from the etching company today:

Dear Rudi,
Your order is confirmed Apr 17, 2012 08:29 and schedule to deliver on Apr 23, 2012.
We will send you delivery details as delivered. Please let us know if had any questions, thank you.

There is an order backlog of about 100 0R1 emitter resistors though.
I will be able to dispatch the international orders in time, but will send the resistors to the German DIYers one week later.

Best regards - Rudi_Ratlos

Good news, the soldering iron is hot.

Gentlemen,

patience is not one of my outstanding virtues!
Waiting for the PCBs to arrive, waiting for the NJL-transistors, waiting for the emitter-resistors, for the 4 x 34VAC / 50W transformer, ...

I would like and start soldering, listening right now - as most of you.

I have already built a prototype.
I know, how to do it, everything is in my mind.

I am currently writing the "FC-100 Builder's Manual".
The manual will be done by the end of the week, and I will write down all the tricks and hints to make this AMP a marvellous, glamorous success.

I will send the manual to all of you.
The manual will be written in German, of course.
You have then 1 or 2 weeks to either learn the German language - or use the "GOOGLE translator".

Slow down, Rudi, and learn to wait.

Best regards - Rudi_Ratlos

Rudi - If you need help translating, let me know! Which transformers did you get?

 

[Rudi_Ratlos]

Martin,

Claus and I ordered a "customer-specific wound 4 x 34 VAC / 50W torroid transformer" from BADEL

(Ringkerntransformator, Transformatoren, Ringkerntransformatoren, Ringkern, Ringkern-Transformator, Trafo)

a long time ago.
The price of this transformer is: 16,20 € + 19% VAT + Shipping.

This transformer is required for the shunt-regulators of the frontends of the AMP, which require +/-39VDC @ 21.5mA per rail.

ANTEK offers 2 x 34VAC transformers as well, but only starting at 200W.

Best regards - Rudi_Ratlos

P.S. Currently I am using a 2 x 35VAC / 160W transformer, which does its job quite well for all of the shunts.

I would be interested in the group buy. Also, whatever parts I need that were not in the shopping carts you provided Also, if you can make some more transistor matching pcbs

schönen abend noch

Add me in the next GB if not possible in this GB.

Gentlemen,

the PCBs have been etched and already arrived at Frankfurt / Germany.
This is the tracking URL: DHL | Tracking | English

In the meantime I have also received another 100 emitter 0R1 / MPC74 emitter resistors.
I am now able to ship all of your orders on Tuesday or Wednesday (depending on the arrival date of the PCBs)
with the exeption of the orders of Claus, Franz, Michael and Duc, whom I ask to wait until the first week of May,
when I am supposed to receive the remaining resistors.

I have finished the FC-100 Builder's Manual in the meantime and will ask a German DIY-friend to proofread the manual.
Then I will send it to all of you via EMail.

Best regards - Rudi_Ratlos

 

[klaus-wick]

Hello,

if someone of these exceptions wants to go ahead in the next week - pls contact Rudi, cause I have no time at all in the moment and can wait till may easy.
best from Ruhrpott / Germany

Extra board arrived safely in Scotland!

Great service!

Gentlemen,

the shipment of the PCBs is currently delayed by the German custom authorities.

I have explained to them that the PCBs are not meant for me alone, that I do not have an "audio business",
but that the PCBs are part of a world-wide group-buy which is processed in this DIY - forum.

I hope the the custom authorities approve our hobby and will release the PCBs very soon.
Maybe they read this post.

Best regards - Rudi_Ratlos

 

[claus1968]

Clearance processing complete at LEIPZIG

 

[Rudi_Ratlos]

It has cost a lot of "Blood, Sweat and Tears" this time.

Best regards - Rudi_Ratlos

 

[Rudi_Ratlos]

I have received the PCBs a minute ago.

The quality is absolutely flawless, and the PCBs look like real gems.

I will now pack your letters and take them to the post-office tomorrow morning.
I will send to all of you the "FC-100 Builder's Manual" tonight.

Best regards - Rudi_Ratlos

 

[Luke]

looking good Rudi, it's been quite alot of work so thanks.

 

[Cambe]

Hey Rudi,
I just had a look at the FC-100 Rev.1 Builders Manual. I didn't even translate it from German to English and still could tell the amount of your attention to detail to the build of the FC-100 amplifier. To all of you, who made this possible, Thank you!

 

[n_dori]

Exellent work Rudi.
Thank you!

Just to inform everybody, NJL0281DG and NJL0302DG are in stock at Mouser!

 

[Rudi_Ratlos]

I took your letters to the post-office yesterday.
I used the "insured letter" option and collected tracking-IDs for all of your letters.

Please take care when you open a letter.
I put the emitter-resistors and 1µF 1839 capacitors deep inside it.

Best regards - Rudi_Ratlos

 

[Rudi_Ratlos]

@Ferrari, FranzM, NullOhm, Claus1968:

I did not yet dispatch your letters.
You have to wait for the last bunch of emitter resistors to arrive, for the NJL-transistors, ...

As FranzM wrote me: "I am still young - I can wait".

I hope you don't mind - Rudi_Ratlos
