How can I measure if my DAC puts out common mode DC from the balanced outputs?

Kerry, Would this Hammond case work 1455Q2202 for the board or did you have something else in mind?

I'm game for 4 pieces. When it comes to testing pots I dunno what I'm doing so someone will have to show me like I'm two years old before I solder it into place.

yep, it does indeed I'd go with 25mm round shaft (25KQ)

Are they talking about shaft length or diameter?

I sent an email to the US distributor

I'm ok with doing a group buy for the TKD pots. I know the US distributor is more than ordering from TKD directly but that may be our only option unless someone can buy from them directly and wants to handle that group buy. What is the correct part number to inquire about? I know it would start with 4CP601 and end with 10K but I don't know what taper is for volume. I assume we want a blank value for the mechanical click.

What's the chances of another TKD pot group buy? I believe Kerry said he would modify the board.

if we can source them I'll add it to the group buy

we've made it to 20 boards so far in the group buy. Any objections to going with 3oz copper? The price will go up about $1.25 a board

If using the RK27 do I need to wire anything differently? I'm thinking it doesn't really matter right? What are the chances of doing a second round on the pots. From what I read on them, I want to try them

if enough people commit we can up the copper to 3oz. Any issues with that? If we can get to 20 boards it only goes up about $1.25 a board

Should we get a stencil?

Board is added to the group buy. Group buy thread is here: Spreadsheet is here: https://docs.google.com/spreadsheets/d/1Z1L3MQuuY4ZTUyPQb1qBmVJp8MtC7qEzBUui3z5dFrQ/edit?usp=sharing

Sure, I can add this to the group buy. Let me check how much it'll be

Since this does all three, I'm in. I started a group buy that included KG's alpsquad3 board so I'll cancel/drop that board if this gets offered. I need 4 as well as one other person needing 2 so that makes 6 I wish I was thinking about this last month, I could've got in on the pots... Dang, maybe someone will sell me one or there will be a second round. One can only hope

is the bigger board compatible with the alps RK27 quad pot?

Yeah, I saw that one. I have a quad alps pot so I don't need one but let me see if I can jump in on that one for just the pcb. Feel free to try and get a set of sorenb's GRLV boards. I'm going to think about all this tonight

Yep, I just found it. I see it's the split boards at $33 per set. I'm partial to the combined board although I know it doesn't really make a difference. Thanks for the info, I'll think about it tonight

sweet... I need 2 at this point but could use 4 in total and there's one other person looking for one as well. Is it the + and - together or separate? What's the price per board? .

Hello All... After realizing I missed out on the latest group buy I thought about having a run of boards made. I believe 3oz copper is recommended for the GRLV and in order to get the boards to an affordable price with that weight it looks like 20+ would do it. While I'm at it, is there any interest in ALPS quad pcbs as well?

is 3oz copper required on the PCB or will 2oz be sufficient?

The original place I was going to use did not have 3 oz as an option. But, I found this place http://www.pcbway.com/ Their prices are better for small qty and they do have 3oz as an option. The problem is it triples the cost of the board. I'd have to increase the order to 20 boards to make it around $10 a board. I think that's doable if I organized a group buy but I've never done one before and was trying to avoid it. Let me see if there's any interest in a group buy

ok, definitely save a set for me. I will most likely order both the power supply and the quad alps board early next week. Looks to be about $133 USD for 10 of each. The PSU should be $8.42 and the alps board would be $4.90 I'm going to use 4 of both so that'll leave 6 up for grabs

looks good to me, have you built a set yet?
