• New repair kits - The most effective way to rebuild stiff bearings or broken parts.
  • Rega arm exchange - If you think your arm is beyond hope, exchange it for a Brand new RB251. For less than the price of many counterweight "upgrades"
  • New Technics SL1210 version - a version of the micrometer arm built into a Technics adapter plate. A drop-in replacement

This is archive stuff from some of the first DIY builds. For current projects, start at the home page link. Lots has changed!

This all started because we decorated the room and once I had nice record shelves and a real equipment rack, not to mention a new sofa, all the hi-fi stuff (which was what the room was for, anyway) started to look seriously nerdy, especially poor old Teres 26 with the sandbox and wooden bits and stuff.

So here, three months and two packs of band-aid later are the results:

Teres turntable

LS3/5a bases

LS3/5a in ebony. Gold tweeters, veneered fronts and backs, Rogers branded.
It's how they came out of the box, honest.

Teres Turntable

This is the rebuild of Teres No.26.
The inspiration was the Marantz TT1000 (right),which uses 15mm glass and aluminium. I thought the Marantz looked cool.

I've used five laminations of 10mm glass and alloy, which is regular stock material. The glass was cut and polished by my local dealer and the alloy made to it.
The motor bearing passes through the outer layers of glass and tightens down on the alloy, using the spacer rings in the left of the assembly photo. This enabled me to keep a fine (about .5mm) air gap between the top glass and the top alloy to isolate the arm board. The top glass is bonded to the aluminium below using the green flocked adhesive vinyl you can see in the dissasembled photo. The arm mount is screwed and epoxy glued to the top glass only.
The other layers are glue bonded and bolted together with rubber/felt washers to protect the glass.

This is the trial assembly to mount the base for the arm mounting.

The whole assembly sits on a lower tray with inner tube suspension. Lateral movement is constrained by felt washers which lightly touch the inside of the tray.
The tray has a felt-covered base to let it sit nicely on the glass stand. Here the turntable has just been assembled. the arm is mounted at the correct distance, but you may be able to spot that the platter still hasn't settled fully. I left it overnight to bed down.

This is the final, playing assembly.

After the last picture, the whole thing came apart again to reduce the height of the acrylic bit the arm sits on by .125", cos there wasn't enough height adjustment.

 

LS3/5a speaker bases

The speaker and equipment stand bases are made to match the record shelves.

The bases were made to isolate the speakers and equipment from the suspended wooden floor. I had the granite (old equipment shelves) and the carpet (left over bits) and even the mahogany left over from the record shelves, so the construction dcided itself.

This is a cross section of the speaker base. The AB1 is just blu-tacked to the granite.

For the equipment stand base, a second layer of carpet is subsituted for the granite and the rebate in the frame is moved up to allow two layers below, two above.

The room isn't really that colour, it's just me trying to get a picture with tungsten room lights...

 

Rogers LS3/5a in ebony

These were 'new old stock' from Stirling broadcast and I guess one of the last sets made up from the original stock parts.
You'll note there's no brand label on the back, though the matching AB1s have real Rogers labels.
It took me ages to realise all LS3/5a's aren't all like this.

This is how I'm running them now. I've watered that sad looking plant since I took the photo.
