Default Rega rebuild help and advice needed

hi guys, need some advice.

I'm pretty sure I know what I'm doing, but if anyone can confirm my thinking that would be great!

Anyway...my old rega planer 2 is in a sorry state. The plinth is pealing, the motor is screwed. Everything else is good inc the tonearm.

With that in mind I'm reabuilding and upgrading.

I've started work on the plinth. Usual stuff, I'm using the old plinth as a template, but I'm going to double up the thickness of the plinth (using ply). So far it's looking good.

I have also ordered a new rega motor. My old one was gritty and slow.....very very slow infact. That should turn up in a few days.


So....in the process of dismantling my current turn table I broke my on/off switch (annoying). I plan though on having no visible on/off switch on the turntable, and was thinking of mounting it underneath using one of these (or similar). Can anyone think of a reason why that wouldn't work?

Finally, my long term plan is to upgrade to a external PSU. Is there anything I need to consider with that In mind?

Feet - I've not put any thought into that. Anyone have any thoughts?

This is my 1st project, so any thoughts Id love to hear them!

The Rega tt-psu is very good quality no reason to consider anything else. Get the matching motor and replace the supplanted with a metal one and enjoy. The switch is fine.

Hi,

Whats wrong with the original feet ? FWIW Rega have
a low density / high stiffness / low stored energy sort
of design philosophy and solid ply might not suit well.
A composite with structural links top and bottom
between arm and bearing is more Rega style.

One thing I will say is if you make the plinth double
thickess the bottom half will need cutouts in the
bottom half to keep all the parts mounting simple.
What you will end up with if done in ply won't
sound like a Rega as they are commonly known.

Look at how their models develop going up the
range for if you want to keep the Rega ethos.

The new motor should come with the improvements
Rega have made over the years, and an external
PSU is probably not a cost effective option for
an old Planar 2. Old arm or the new one ?

rgds, sreten.

I have an old Planar 3 and after asking around decided it wouldn't be worth doing the mods, either motor or sub-platter and certainly not the motor AND PSU. There is a pitch problem with it that I hear when playing piano music, or even worse, the opening to Stairway to Heaven. I don't want to spend $200+ only to find out it is something else that is wrong.

Just cleaning and lubing the bearing made mine much quieter, and I also fixed the motor to the plinth with double stick tape. A new belt is still needed, and I've been looking at cartridges to replace my low end Sumiko Pearl. I posted in another thread asking about a Jico stylus for the Sumiko, but I'd rather just get something else.

You're on your own with the plinth, but I'd tend to agree with sreten above.

Look at the pulley.
Sometimes the pulley slips on the motor axle.

I'm helping out a friend who wants some engineering drawings for a Planar 2 / Planar 3 to kick about some ideas. As I don't own one of these decks I said that I would draw some up if I could get some dimensions and would ask around here so please forgive my post on your thread.

I wondered if anyone had any accurate drawings or would possibly take the time to measure up everything on their P2 / P3 deck for positions, dimensions for holes and cutouts, motor and pully sizes etc?

Appreciate the help.
