Thanks Rudi/JP, I will check when I get home tonight and post anything I find.
Rudi, the software will be for classic 2x16 displays ? I would like to enroll to this GB but i have already cut the aluminium enclosure preamp for 2x16 display like it was the version with temperature sensors.
Gentlemen, I have subscribed to an occasional holiday-offer (?- do you understand, is this good English?) and will not be available
from end of July to middle of August.
To make this group-buy a success nevertheless, I have ordered 20 PCBs of each (VCPre_PCB, Auxiliary_PCB) and components already today!
I hope to recieve them until middle of July and send them to you ASAP ( before I start my vacations).
@Palmito: I have spent some time searching the INTERNET for a Small_Print_Transformer that will make you happy. I have not been sucessfull.
I have therefeore decided to remove the paralleled-tracks on the VCPre-Layout. I feel a little bit sorry upon having taken this decision.
Best regards - Rudi_Ratlos
P.S. I will continue this group-buy (2nd-round) for everyone who will sign_in later (profiting from the appreciation of the 1st - round - buyers).

I could not find one either, but had not given up yet. It's perfectly ok, I will keep the trasnformer off board. Please keep my order as it is now in the spreadsheet, no transformer.
And thanks again for this group buy!
Rudi is there any room for me on the list ? I don't need the additional pcb's but i need some more relays (i remember you offered relays few posts ago).
Thanks!
Thanks!
This is all I could find. It's .3A if you parallel the secondaries and is 230 or 115v primary.... Just not enough juice I think.

Have a good holiday in july, Rudi!
Could you post payment details on this page? I think it's the least we can do for the quick service you've been giving us 🙂

We use those in our DAC power supply and it is good. Silent and a low stray field. If this will be used on the PCB only a wire bridge is necessary for 230 V use and none for 115 V use if one orders the 115 V version. See our DAC PSU and BOM for type numbers etc. We used it to make our DAC PSU versatile and suitable for use in all countries.
It needs larger pads/holes than standard EI38 transformers though !!! It has wider pins. I would be surprised if it does not have enough juice to power the VCPre.

@Palmito: Maybe it is best for you to wait for the 2nd round of this group-buy. I will start it when I am back from holidays,
in the 2nd week of August.
I have just drawn a "package" (this is the EAGLE term of the representation of the foot-print of a device) of BillyK's and Jean-Paul's
recommended TAMURA transformer (I appreciate your recommendations, gentlemen).
The TAMURA transformer will fit on the PCB (see attached image), and I will (perhaps) make it the standard transformer in the 2nd round.
I will once more check the power dissipation, but - from a first view - I think that it will be sufficient.
Best regards - Rudi_Ratlos

@Wirehead.be:

This is a good point!
I have already ordered 20 PCBs of each and 20x25€ worth of LDRs!
My PAYPAL - account has run out of money, and I would appreciate very much, if you transfer the money (as shown in column TOTAL).
My PAYPAL-Id is: RRozek@t-online.de
Please make sure that your EMail- and home-address, as you have left at PAYPAL, is correct.

Billy: you are the 1st one to pay. Thank you very much.
Best regards - Rudi
P.S. You need not be excited! Lean back and watch the stories' growth!
By the way: I have "outsourced" the job of matching the LDRs to "Mr. LDR" himself!
He has of course much more experience with LDRs than I have and will provide you with perfectly matched quads.

That's good news about the LDRs.
I am excited to be a part of this although I am not much important, just having fun.
You should have seen my face when I first read about it. I am currently in the process of putting together a unit that consists of almost everything your ONE board does! I have a LCDuino and Delta 2 board from Ti at AMB for control and switching along with alpha 20 buffers, an LDR board for attenuation, jean-paul and Subbu DAC with JG buffers, a nice phono pre, all with Salas BiB shunt regs. for power. I have been planning this for months and all of a sudden here we are!! Too cool.
This first VCP will be combined with a Fetzilla for what will be one heck of a nice integrated!! W00t!!
