Tone and Balance Controller Daughter Board

Have you considered adding a tone and balance daughter board to the group buy? Here are two articles from Wired Magazine that have specific designs.
Let me know what the group thinks about a new daughter board.

If you can get the 110v transformers I would like to purchase them from you as well. We can sort it out when you get back from vacation, Have a good time.

thanks

Just checked my amp. It seems to be my vcpre board is too close to traffos and amplifier board's power supply.
Can I put vcpre into the separate enclosure and still use one remote to switch on and off both units ?
Let's say my pre is controlling power amp ?

the other question how close is too close 🙂

Put one picture to see what mean "close". If you have toroidals i think it's ok, you can use also some techniques to lower the trafo radiations using some copper foil.

Sorry it is late to open amp, here is brief sketch of inside
basically vcpre is in the middle of enclosure, between 2 channels, gap is barely 1 cm each side, even less.
Inlet run under, but I can use spacers to lift the board quite high.
And it is close to traffos..

You are not late but Rudi is on holiday now. I think you are right on time for the round 2 of GB.

I think so too.
I wouldn't worry too much. If this is going to be as nice as I think it is there will be more available!

Does anybody know of any mercury wetted relays that will fit the PCB footprint? I would like to follow the contactless philosophy of the original lightspeed attenuator as closely as possible.

Gentlemen, many regards from Föhr ( a German Northsea Island), where I am on vacations currently.
I am sitting in an "INTERNET CAFE" in Wyk (the capital city of Föhr), it is very hot (> 30°) outside, and I have my USB - stick with me.

Find attached the current order list.

Since I have already ordered all of the components (PCBs, TAMURA transformers, chips, matched LDRs, ...) ,before I have left for holiday,
I would like and ask you to do your PAYPAL transfers right now.

EMIL: I have counted you in for the 2nd round, but: I have only ordered 20 matched quads of LDRs from Uriah a week ago!
You are the 21st, and I kindly ask you to order your private quad of LDRs from Uriah directly!
FEBRUARY LDRS
The price that you have to pay will be similar to my one!

I am wishing you all the best, enjoy - Rudi_Ratlos
