Regarding the inversion, I noticed this when I traced through the board and wondered too, but there is an inversion at the relay as well, so in effect, everything remains in phase.
OK, I've had a new quote, and I'm undecided what to do. Doing a small run is a lot more expensive - works out at around 2-3 times the price per board.
We got an incredible deal last time but that was because we did a run of over 100 boards! I'm not sure I want to subject myself to another cost of 100x boards and the few man weeks in managing the GB especially as I had no guarantee they'd all go...

Still no sign of my board which arrived in Canada less than 24 hours after posting in the UK.
After countless hours on the phone to both Canada Post and Canada Customs, navigating menus that are designed to make it almost impossible to speak with a real live person, I managed to confirm that my board is 'probably' at the Vancouver Customs Clearance facility and that they are currently experiencing a turn around time of up to 46 days!
It seems a shame that for all the effort that Xavier went to, to be undermined by Canada Post and/or Canada Customs - one has to love the unions!

So sorry to hear that Clive. I do find it strange though it should take this long. Surely the whole trading business cannot be held ransom to 46 days' clearance lead time. That's just mad!
It's also a shame I cannot get any more detailed tracking once it hits Canadian customs. In the US, the tracking numbers work with USPS so you can see local tracking. I don't think I can push from my side 🙁

Hi tfboy,
There are momentarily 33 unpopulated VolCB's on order in the Maya GB, enabling remote volume control and channel select for the BPBP.
Tibi, doing the GB for Maya, also willing to supply unpopulated VolCB's, just replied to me that he is not able to supply populated versions for an amount under 200 pcs.
So my question is, would it in any way be possible for you to combine the BPBP and the VolCB in the new GB that you just started?
It could give a positive impulse to the number of BPBP boards.
Kindest Regards,
Hans
Hans, to be honest, I'd want to simplify things. Managing bare boards, assembled boards and pairs of Hypex regulators made the logistics a bit of a nightmare, so a new GB would most likely be for an SMD-populated board version only.
No problem cross-linking our threads though so everyone can see the volume control option as well.
The biggest cost increase on the BPBP when small quantities is the assembly and bare board cost (the components are a little more expensive, but only like 10-20%).
I haven't checked Tibi's thread / technical details, but he'd be more than welcome to get a quote from Quick Circuits for the PCBs, but the larger the number, the more cost-effective it is per board.

Hi tfboy,
Thanks for responding so quickly.
I understand your position, maybe somebody else can take the challenge, it would seriously drop the costs.
Your suggestion of cross linking the two GB´s, seems like a good idea.
Kindest Regards,
Hans
To be honest, as the design isn't the same, there wouldn't be many advantages (at least with Quick circuits) in combining them. I've asked for them to quote several jobs simultaneously, but there's no saving to be made compared to doing them individually.
Thanks again.
I have asked Quick Circuits for a quotation, immediately after your first reply.
Hans
Can I be put on the list?
I would love to have 2 boards (populated that is) for my bi-amped Open baffles.
What should I do?

I'm trying to use a remote switch on my front panel ,bypassing the PCB toggle switch S1.
I intend to mount a remote rotary switch, connected to the PCB with flying leads.
I'm having trouble working out how the original switch S1 operates. There are four pads on the PCB for this switch which I will call 1-4 with 1 being nearest the board edge.
My understanding is this.
Pin 1- ground connection to switch body
Pin 2- connection to relay K2 (on rear of PCB)
Pin 3- ground connection
Pin 4- appears to have no connection, unless there is another layer.
Testing the supplied switch shows connections to pads 1,3+4 in one position and pads 1,2 +3 in the other.
So is the switch only connecting relay K2 to ground in one position and the other position doing nothing other than break this connection ?
Many thanks in advance.

Hi Paul,
Yes, switch is either shorting effectively pin 2 to ground or not, leaving it open.
I don't have the board to confirm, but looking at the traces, the switch controls the return of the 12V relay feed. If closed, it closes the 12V circuit, energising both relays. When open, the circuit is open, the relays aren't energised and so default to the other position - they're not latching relays so need constant voltage across coil contacts.

Tibi has just announced in his Maya GB thread that he will close the list at June the 1th.
So anybody still interested in combining BPBP with a remote, should make up their minds quite rapidly.

Who makes that pot out of interest? Someone else used the same I noticed but I wasn't quite sure which to go for on Mouser.. Getting the longevity/cost ratio needed a little thought but in the end I paid out for a Vishay one.
I got the one in the BOM drpro posted.
Mouser No: 72-P9A2R100FISX1103M
Mfr. #: P9A2R100FISX1103MA
Manufacturer: Vishay
Desc.: Potentiometers 10K 20% 9MM MULT GANGED
Ah well great minds think alike - I chose the same one after looking through the list of 10k pots on Mouser. Well I might have chosen a different thing to the slotted one.
