Wow the platter and bearing design is superb with the lighting, I bet listening to it would have enhanced effects.  Its in a different league compared to what I am doing :)

if you are spraying yourself try the rustoleum sprays...I've had good success with them on metal chassis...otherwise I would take it to a shop that does powder coating or high grade enamel like a car workshop perhaps.


this was a hammered look paint from a can onto metal and PVC (the round part) and best to use a primer too of course.

I have a pile of stuff that pushes out squiggly waveforms from smaller squiggly waveforms that sometimes come from 1's and 0's.
It's wonderful to behold as long as you don't let the magic smoke out.

just curious .... how to really finalize the tonearm positioning?

i mean... we are not really doing with precision tooling... so how can we know the tonearm is in the correct position


XYZ table for the tonearm?

Thanks Nic, always good to hear this from an old friend.  Cutting down and slowly getting rid of my stuff and finishing those that were still in the works.  I need to clear my cabinet of goodies which my wife call junk.

Highly subjective question!

Commercial TTs which are mass produced are not engineered to that kind of precision.  So are the tonearms.  From the base where the tonearms are mounted you inherit all the good stuff if they well made and not tilted. If you remount the TT on another plinth that is perpendicular to gravity then if may help further.  If you outboard the tonearm you get flexibility of a xyz adjustment rather than the usual xy axis.  Then there is the counter balancing and cartridge alignment.  After that you need to adjust for optimal tracking force which differs with each cartridge.  The turntable probably has the most number of steps required to optimize the final output you desire, aside from vibrations and other factors which may drastically affect what you hear at the end.  There are hardly any tonearms that will let you adjust xyz to really align to the LP on the spinning platter.  If there are then its definitely not that sub 1k price range which most can stomach.

In my own observation, the TT has to be set up like new over and over again when you move it from place to place.  Unless you bolt it dead at a fix location, there will always be movements of the parts which requires constant adjustment.  Given the number of movable parts I don't think there is a perfect TT in this world, but I dare say there are lots of very well optimized ones out there.  Well there are always the CD/Media players if you just want a simple song.  Just my own opinion, didn't plan to start a war but definitely welcome active discussion.  Peace! in advance...

Bit late now but I might have left room for some more arm mounting options down the road. I probably would have done a multi layer plinth glued and screwed to get at least an inch or so below the motor for a more weighty base.


My ptp sits on 22Kg+ of slate that was cut out with water jet. Plinth weight is a huge benefit for TT's.


Some higher end pressings play at 45RPM spread over 4 sides for a single album...to improve the groove separation so you might want to have that 45 option. I often get caught out and have to adjust things to play more than a few of my albums that are releases on 180gm issues.

Sharing via summary in google drive as most of the photo hosting site are not friendly towards what I wanted to do.  Anyways I am into my last amp rebuild for the year!  Rather happy with the progress and hope to complete as intended.

Thanks Jaffrie!  No choice just too many already.  I am rotating between 4 or 5 Amps and 2 sets of speakers.  Plus tube amp parts are heavy and take up lots of space.  Think 3 will be ideal for my case :)
