Does anyone here have experience with the SEN I/V stage? I want to try this with my BIII http://www.diyaudio.com/forums/digital-source/195483-zen-cen-sen-evolution-minimalistic-iv-converter.html

added this board and the BH Ultramini Version 4 to the latest group buy https://docs.google.com/spreadsheets/d/1Z1L3MQuuY4ZTUyPQb1qBmVJp8MtC7qEzBUui3z5dFrQ/edit?usp=sharing

Spreadsheet updated with the CFA (electrostatic) and the BH Ultramini HV PSU

I'll be adding the electrostatic one and the bh psu

seems prudent to use it then if you ask me

I'll add it then. congo5 says it works and sounds nice. This is the gerber http://gilmore.chem.northwestern.edu/boards/cfaelectrostat2.zip This power supply was reccomended by congo5, any objections? http://gilmore.chem.northwestern.edu/boards/kgbhultraminipsv4.zip

You got it... For the Current Feedback amp, is that board still being tweaked?

They're added

Yep, I'll add the smt boards

VAT payment sent

Okie Dokie... The sheet is open https://docs.google.com/spreadsheets/d/1Z1L3MQuuY4ZTUyPQb1qBmVJp8MtC7qEzBUui3z5dFrQ/edit?usp=sharing So far we have the GRLV combined and split, the Unbalanced\Balanced board (through hole), the diamond buffer (through hole), the dynalo, and dynalo mini with TKD pot. Of course I will confirm the boards are ok and in final versions. I would love to build the CFA so I will check to see if it's possible to add that board as well.

noted... I'm hoping to open up the spreadsheet tonight. Been a little busy and it's my son's 17th birthday today (time flies)

Am I going to need an oven for my birthday? Or, will there be a through hole version with the diamond buffer included? Ducking as well If not I'll be fine with four or the through hole buffer boards and the unbal board

Yeah, I definitely am a glutton for punishment I'm interested in that board as well

Hello All... Since there were a bunch of requests for more GRLV boards I'll do another round. I've also added the boards listed below that are in demand. Also, as a side note if you're looking for boards from my last GB I have one set of Dynahi boards, four or five Dynalo Mini, and a few volume pot boards left. Send me a message if you need any of those.

Now we're talking... So if I understand that would go after the output from the unbalanced\balanced to balanced board. Is that correct?

I understand... That was an excellent explanation, thank you

For my tube amps I would need the dampening circuit according to jensen. For best response it says to keep my cable run under 2 feet. I might make a box separate for each tube amp. That would keep the cable run under two feet.

Here's the schematic on the jensen website http://www.jensen-transformers.com/wp-content/uploads/2014/08/as089.pdf It will go starting with a dual mono BIII to a passive 1 in 3 out xlr switch box (the transformers will be one of the three positions) to a 1 in 3 out RCA switch box. D you guys see any issues with that?

I think this might be the best solution... anyone else do this compared to an opamp based solution?

So I'm looking for Purple Rain and 1999 in high resolution. qobuz has them for download at 96\24 Any thoughts on those? 1. can I download them in the US 2. can I play it with any player 3. how do they sound

Sorry man... I meant to do it earlier but it was too cold in the basement that night. I'll have to check Arrow out

Here's my mouser list. It includes resistors for 15, 20, and 30V. No voltage reference chip. I ordered those direct from linear, it was cheaper than Digikey. http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=fba137c169

cool, thanks I'll check what size caps are on the amp boards
