14 mm above the threaded part for 4CP-601, 10 above the threaded part for 4CP-2511, if I remember the data sheet correctly.

Good news; customized shaft lengths can be had at an additional cost of about 1 USD per piece, and min quantity is 1, which means @UFN can have the length he desires without that affecting anything else. Bad news (for GeorgeP): custom thread length was not possible. UFN: please tell me how much extra length you want for your pots. Anyone else who also want longer shafts; let me know. I will close the GB tomorrow. Those who have not paid but who are still interested, please make your payment.

A good argument in favor of big knobs . I like it. I'll ask TKD then if our GB could have the option to do a slightly longer shaft, and report what the conditions (number of pots) for that would be.

Noted. The first step is to ask if they can do what @UFN wants, and what the minimum quantity is for doing that. If enough are interested and minimum quantity is low, we might make that an option. I usually do thinner panels than 10 mm, so some portion of the GB will definitely be standard length.

Not yet; there's been quite a lot of PM discussions on details and custom values that I need to ask TKD, and I though I'd put them in one e-mail rather than shooting a barrage of questions. Since you found that they do can special length shafts, could you tell me a little more detail about what would you like to see extended (given that we meet their minimum quantity requirement for this) ? Would you only like the threaded part extended so you actually can fit a nut on the other side of a 10 mm front panel, or do you also want the shaft extended (and if so by how much), or would you rather see both extended (and if so, by how much for each part)? For my part, I usually countersink from the front or tap from the back of the front panel when it's 10 mm (the latter takes a couple of washers to get position right, but works surprisingly well), but I can see the advantage of not having to do either of these

UPDATE: there seems to exist a sufficient interest for both the 4CP-2511 10K and the 601 in 50K version, so they are now back in the spreadsheet.

It's fine, and money is received. Thanks!

Received. Thanks!

Received. Thanks! Received. Thanks! Noted and no problem!

Don't know, have never seen it, but I can certainly ask Received, thanks!

You're fine, just in time I'm collecting payment now, so just paypal me (paypal address above), and please include your Head Case ID in the message. No problem and great

Payment received, thanks! Mwl168 is handling the boards, so we'll have to see if he expects pre-payment for the boards prior to ordering or if we'll collect costs dor shipping and boards in one payment once the packages go out.

Well, it seems like all who wished have stated their interest in the spreadsheet. As it sums up, the 50K version of 4CP-601 does not have enough entries (minimum is 5 units), so it will be dropped from the GB. @gepardcv and @obiwan: please check your entries and make sure you are happy . I will now start to collect payment for the pots. Each participant, please paypal me the amount under "price total" on your row in the spreadsheet. My paypal adress is [email protected]. Please include your head-case ID in the message box. Once all payments are in, I will place the order with TKD. Note that the current payment covers having the pots made and shipped to Sweden. Costs for onward postage to where you live will be collected later once the pots are in.

While at it, would it be possible to test some terminal blocks as well? I've tried to figure out what the UI tests for those 300-400V ratings actually mean. I don't get it fully, but DC seems less of a problem than AC in those tests...

Not a dumb question. Apart from being bigger and having solder lugs rather than pins (which makes it a whole lot easier to mount unless you have a board for it), the 4CP-2511 has exactly the same electrical and mechanical properties as 4CP-601, at least according to TKD's data sheets. I'm not aware of any serious shootouts between the two soundwise (A/B testing style), if others have please then please chime in? I've only used 4CP-601s and am very happy with those (the ones I've gotten track well and have excellent rotation feel) but of course the much higher price must include some magic to make it worthwhile. Only one way to find out...

Steep learning curve here Now I think I've unprotected all the right things.

Thanks for letting me know; turns out I had set the sharing features wrong. Now it should be editable. I've added your 5 to the table.

GB INTEREST SPREADSHEET: state your interest for pots and boards in the spreadsheet below (and if you find errors, please let me know). https://docs.google.com/spreadsheets/d/1O_LNaSDBViihkC0dNcYe46SqjOwteiTFmRmuXMRY4fA/edit?usp=sharing The POTs section of this GB is now officially closed. Entries for pot boards (type and quantity) can still be updated and edited.

So, quotations for the 4CP-2511 10K are in, and the cost will be 105 USD per piece plus shipping from Sweden to wherever you live. No price break below 500+ units, sorry TKD can of course do 50K or 100K versions of both the 601 and 25XX, but min qty is 5 pieces for any particular configuration. I've cloned a "wants it" spreadsheet from sorenb's masterful original and populated it with interests already expressed in this thread (see link in next post). I will leave it open for a few days for people to add/change things before asking for payment and placing the order. I've also put in a column with interest for pot boards. There is no quotation for these yet, but I figured it makes sense to have the interest check for those in the same place.

Yes, depending on final interest (they don't do smaller qtys than 5 of any item for this type of direct purchase). I haven't received the quotation foe those yet, but don't expect a price break unless the GB reaches 500+ units...

Thanks for the heads-up! My previous ones were all good, but if we go this route, I'll definitely test all of them before shipping them onwards. Seems you've gotten bad product a couple of times now (Toroidy, TKD). Is this just random bad luck, or are quality checks not in place at these companies?

So, I received a quotation from TKD this morning, and it seems the pricing of 3200 JPY per piece (what I've paid before) still stands. In addition there will be shipping and customs fees for entry to Sweden, so in total, this makes a GB price about 42-43 USD per piece + shipping to wherever you live. Price breaks can be had for orders of 500+ units, so not an option here An important factor is that production lead time is quite long: 45-60 days after payment. In other words, don't plan to use these in any immediate builds...

Interesting, I paid 3200 JPY a piece in April this year, plus another 2900 for the shipping. 10K would be my preference.

For those new to the thread: there is enough interest, so a GB will take place. State you interest in the GB INTEREST SPREADSHEET (link below) https://docs.google.com/spreadsheets/d/1O_LNaSDBViihkC0dNcYe46SqjOwteiTFmRmuXMRY4fA/edit?usp=sharing The POTs section of this GB is now officially closed.

Money sent. Thanks!
