Just let me know the total of the the relay board and selector board. I am in Nashville, TN USA.
Thanks
David

That's STANDARDS my friend! Way to be picky on behalf of others! FWIW, I would not have groused about receiving that, at all- it's not a functional issue! And, got mine, lookin' great. Just have to figure out all the parts to stuff the rest of it, and a chassis.
I think the smd soldered board needs:
- Two of the three 10 pins connectors
- the selector connector
- the relevant ribbon cables
Does anyone have the exact parts number of the above?
Thanks!!

Hi Fred,
Tonight I will post here the part numbers that are useful to everybody.

Here the part numbers:
- Pins connectors - Digikey 3M9460-ND
- IDC ribbon cable - Digikey H3CCH-1006G-ND (other length available)
- Rotary switch - Mouser 611-A20503RNCGE
General info: if you bought the BP board already with SMD parts soldered is not necessary to desolder the input res and caps. Without the 2 original relays they will remain isolated.

Enrico

Q1 - Yes to both
Q2 - I don't understand on what you are referring. The parts you mention I suppose that are part of tfboy GB, so ask there. The rest of parts in this GB are well mentioned
Dear All,
In this thread http://www.diyaudio.com/forums/analog-line-level/291226-remote-control-bpbp.html Hans Polak propose an interesting integration of the BP preampli with the Maja remote control. He proposed 2 boards:
- VolCB, expressly designed for Maja to manage the Volume and the Input selection
- 4 Input board that, through signal from the VolCB, will switch 4 inputs.
Even if is a clean and well done solution, personally I don't like the solution adopted for the inputs selection, At the end there 6 XLR from the BP + 12 XLR from the Input board to manage 4 inputs, 1 tape line and 1 out.
Anyway, I am thinking to make a small interface board to manage the 6 input board of this GB with the VolCB of Hans having all the futures of Maya and without changing anything in the 6 Input board.
The cost is depending on how many people are interested. The parts are not expensive and as usual the cost of the PCB is defined by the quantities.
The small board that I want to do will be inserted between the input ribbon cable and the relevant connector in the 6 input board.
I will post here the pcb design in the next days.
Best Regards,
Enrico

Interface for the VolCB - Maja Remote Control
I get all the clarification that I need to make the 6 Input board working with the VolCB designed by Hans Polak.
Hans still believe that the best solution should be to change all the relays at 12V to the ones at 5V. In my opinion the solution of a small interface board is still more chip (and easy) if we can realize at least 10 boards. The cost is for the PCB itself, more boards I order and less will be the unit price.
Anyway, attached is a small sketch where you can see (RED) the interface board that, in one side, will be directly connected to the 6 input (YELLOW) with a female 10 pins and in the other side will connect the 10 poles ribbon cable (GREEN). It's the same cable that you already have for the selector board. You need just to cut the connector on the side plan for the selector board and solder directly in the VolCB that already have the pads for the 6 relays. It's very easy and I will post a detailed sketch where you will see the pads.
Please give a look and let me know if you need any clarification.
Best Regards,
Enrico

Forget to mention, the boards will be fully populated and tested unless you don't expressly ask for the bare board.
Hi Enrico,
Your interface board looks like a nice and elegant hassle-free solution.
Hans
Hi Enrico,
I´ve sent you a PM with an idea for an alternative for the hex buffer/ULN2003 giving galvanic isolation between Maya and BPBP.

Hi Hans,
I replied this morning to your PM. I hope you received it.
Tonight when I back home I will post here your nice solution that I fully agreed.
Thanks for your kind support

Interface with VolCB - Design review
Today I have a nice conversation with Hans about the best technical solution to keep the GND of the BPBP and the 6 input board galvanic separated from the GND of the Maya that, as correctly noted by Hans, normally producing quite some pollution on the supply lines.
So, the agreed solution is to use 6 relays reed that will interface the 12 relays in the 6 input board.
Hans also kindly agreed to add a 8 pin connector in the VolCB for a ribbon cable between the VolCB board and the interface. This will make the interface board a real "plug and play"... Thanks Hans!
The board will be very easy to realize as no SMD parts are more required.
In few days I will post here the picture of the interface board.
This are the components:
1 - Female header 10 pins WURTH - PN 613010243121
6 - Relays reed COTO - PN 9007-05-00
1 - Ribbon cable 8 pin TE - PN 2205070-2. One side of the ribbon cable come with the connector to be soldered directly in the interface board. The other side is to be plugged in the VolCB
They are all through holes so feel free to ask for a bare board or if you prefer I can make and test the board for you.
NATBERG, Lbud4 and pchw please review you choice specifying if you want only "bare board" or leave as it is if you want the boards done and tested.
Regards,
Enrico
