I sent some free 8-legs to a Canadian member and to avoid hassle I dropped them (stuck in ESD foam) into the mail as a <1oz letter. The cancelling machine crushed everything.
I bought some chips from Canada and I had completely forgotten about purchasing them by the time I got them six months later. I have no idea where they got lost during most of that time. They were posted within days of purchase.
I have heard similar tales of things getting crushed in the regular mail even here in the U.S., although I don't think I have experienced it. I did get a severely warped record from Amazon once. (Someone in shipping actually bent the record to place it in a slightly too small box, not urban legend.. LOL) For a long time I avoided purchasing records from Amazon, these days no problems.

I'm in touch with GZ Vinyl in Prague, but thru their Canadian arm, since I'm in North America. The mastering would be done in Prague, the pressing in Canada. I already have a quote and am about to send a list of technical questions them.
FWIW, they are just finishing up a setup/test LP and the clients are very happy with it. That's all I know about that project. GZ also made test LPs back in the 70s.
Then there isn't a problem with record centre hole tolerance, which kick started the whole thing ?
Actually we're probably looking for smaller houses that 'get-it' in terms of a special run and customisation to high tolerance and precise levels................ Fundamental is post production and mastering, and that just can't be standard in this case.........

Unfortunately my current TT has a spindle slightly smaller than the RIAA min standard, I suppose so no one ever gets a stuck LP.
Understood, but unless we have an "in" with a a mastering house we have to go thru normal channels and ask the best question we can. Getting that special service could be difficult and $$$$. I'm trying to find out how to do that.
Maybe we can get Pavel to take the GZ Vinyl engineers out for a drink and plead our case.
Well in the middle of 2 weeks off to burn unused leave as most of my team are taking half of december off. Jobs for SWMBO done in the house. Been hacking and shredding in the garden as well as filling up 2 new compost bins. But got time to mount a cheapy drill press so I can start drilling holes to put them in a box. But first I have to test. Reminds me should bring the scope inside to warm up ready for tomorrow.
I am rather looking forward to youngest one going to be at normal time and sleeping through the night as really limits time to do things!
I may have missed it, but did we discuss if there was any benefit in a pink noise track for quick FR measurements or is it more trouble than its worth?
I have been angsting over the bedding in concepts, but suspect unless you have something you did earlier we just know too little about it to even speculate so it should be left off unless Canis ex Machina appears.
Only thing I can't see that I can do with that is measure distortion for non-mono signals over frequency as there is no vertical sweep or single channel sweep. I probably again missed where this was pointed out to be unnecessary?
Here is a suggested track list from post #228
I don't think the sweeps above reference value are possible because of high end clipping, so those spots are open

It's a question on my list. What's the amplitude limit at high frequencies?
Interestingly, if you put the average spectrum of most music thru a reverse RIAA filter it comes out flat(ish). In fact the average spectrum for hip-hop is almost the RIAA playback curve itself. Meaning that after the reverse RIAA used in mastering, the musical signal recorded to disc is basically flat. Since sweeps start flat, the top end would have to be cut very hot. White noise the same, so pink is probably safer.

From my recollection Czech vinyl was considered in many circles to be the best there was.
I’m not sure if that’s still the case or if the Canadian plant would use the same raw materials.
Why are we trying to test the limits of tracking for cartridges anyway? There are test records out there that do that. I think our test signals should all be in the normal range encountered with real recorded music (and not the 1812 either!). If a cartridge doesn't track well, you already know this before running a test record. So this is a waste.
I would think that what we want to know are attributes for the turntable / cartridge as a system under normal circumstances.

Would it be possible to know more about the track list? I suppose the actual content is intellectual property, but the track list perhaps not. Just for not reinventing the wheel...
I suppose I could ask. Worse they could say is no.
The initial quote is $1590 for 200 LPs in 140g vinyl with color printing. Going to B&W printing almost offsets the cost of the 180g upgrade. We'd be at $1620 that way. Cheap! Only $8.10 a record. But add on top of that shipping (est $185 to me in Florida), credit card fees, a percentage if we use a funding site like KickStarter to fund them, margin for returns and damages and unsold, and we're quickly up to about $12. I put the price at $15, as a safety margin. I don't know if, or how much, import duty there would be from Canada to the USA.
Shipping out is another matter. I'll ask if it's possible to press 100 in Canada, and 100 in Europe. Sunsun has offered to distribute in Asia.
