Interest check on Vicol Audio Maya R2R Volume controller

[Philipp23]

Hi Tibi

Great. I'm really excited to get the Maya Volume Control.

Do you have a timeline when the shipping will begin approximately?

Don't misunderstand me, the question should not imply that you have to hurry up or so. I really don't want to stress you.

Best Regards and enjoy you Sunday

The project is ready since May, but we need more people in GB list to make this happen.

Few pictures with prototype have been presented on our twitter account https://twitter.com/Vicol_Audio/status/600201375549620224/photo/1

I sent an email about a volume control/Input selector before finding this. Lampizator put me on to you guys. I am really interested. I would like a prebuilt board, but wonder what parts will be used on the prebuilts? Also, what number do you have to reach before you start the project?

 

[sfox7076]

I have a question though. I need a 100K output for my tube preamp. How can I make that work?

 

[aradan]

This build haa unbuffered outputs. Your questions is more about which buffer should I use to get a 100k resistance.

Have a read about buffers in other threads

You will need it to make the volume control work as pre amp any way 🙂

 

[sfox7076]

My basic idea was to build this volume control into the front end of this schematic and leave out the auto former volume controls on the back end. http://www.diyaudio.com/forums/tubes-valves/258974-6ah4-preamp-great-option-line-stage.html

Any Bluetooth control solution for IOS?

 

[iTiberius]

For iPhone and IPad we are testing a new LTE bluetooth module. We are using a very simple but proprietary protocol and IOS is more "restrictive" on such things.
So, for the time been, Android is fully supported, an alpha SaifishOS is on the way, IOS still in hardware and software development.

I have to figure out how I will wire the heaters, but my plans for a 12sn7 or 2C50 are coming together pretty well. Still think I may buy 2 and make a 6AH4 preamp as well.

Just a reminder, the list for this GB will be closed on 30 Sept.

What is the time horizon on the completion?

Hi Tibi,

I might have missed the part about the power supply.

What power supply is needed to power the Maya ?
