This project was
absolutely an exercise in persistence.
I had
previously restored my parents' old turntable, but the plastic hinges on the lid were broken, which made it awkward to use long term. Even the stereo system in that post got shuffled around and packed away in the shed as not-strictly-necessary.
Fast-forward a few years into a more dystopian future and an ongoing pandemic, and we find me, spending a lot of time at home, looking for projects to distract myself. I had recently gotten
a 3D printer for the first time, and I came across a
kickstarter for the SongBird turntable kit. They would supply the hardware, electronics, acrylic, and 3D models, which you then print yourself at home. This seemed ideal to me, because if anything ever broke I would (or at least should) be able to replace just that part easily. I backed it in May.
The kickstarter campaign fulfilment was a bit delayed (by the creators catching covid), but not for long as all the parts went up on
MyMiniFactory in October, followed by a few updates (that resulted in a naming schema I could not follow). I read the instructions, and decided to not make things difficult for myself and to simply use PETG like they do. I'd never used PETG before, so I did a bit of research and ordered some filament (
ROSA3D PETG Standard Light Green and
ROSA3D PETG Standard Black) and a
Spring Steel Sheet applied PEI Flex Plate for my printer. They arrive, and I print out all the parts before the end of the year.
( Parts list )But we all know a turntable cannot be used on its own, it needs speakers, and a preamp, so I have to dig out, and clean up, my old stereo system and preamp. I found my old Cambridge Audio 640P preamp, and couldn't find the power plug. So I order a replacement. All this takes a while. June rolls around and I, at least, finally get all the parts assembled into a turntable!

I also needed furniture to fit the stereo into my office, which had to be found, ordered, stained, and assembled. Which required rearranging other things, changing power strip layouts, and then
I get covid. This takes a while.
In the instructions they say we need a 'Rega Baerwald alignment protractor V2', and they provide a link to a forum, that is shutting down leaving the file inaccessible. I bought an
alignment protractor, but I'm glad backers are sharing copies of the file in the comments now (not least because the place I got my alignment protractor no longer seems to be stocking them).
I finally get enough energy to do the rearranging and I realise I do not have two sets of phono-to-phono cables, and that I really need two sets of phono-to-phono cables. I also find out that I have to order them, because nowhere locally physically stocks them?!
Everything arrives, and I'm setting it all up, going through the fiddly calibration guide, and, it's not working. I get the multimeter out and take the turntable apart. But everything seems okay. I try the stereo system AUX with a portable CD player, and that's working. I even test the brand new cables. That leaves the preamp. The power light comes on, but there's no sound coming through. So I order a replacement, the
Behringer PP400 Phono Preamp that they mention in the instructions. Which means I can also print the preamp mount part (pa1mk3-1), to tuck the preamp under the metal arm.
Printed in black;
- pa1mk3-1, at fast quality (3 hours), doesn't look great, but does the job. (Slicer also complained model had problems that it repaired.)
A month later the new preamp arrives, which I attach with two M3 x 5mm screws, and I wire everything up. Finally I can listen to some vinyl.
