Upgrade for users of 1/2" mylar belt

This thread will be of interest to Galibier, Redpoint and Teres belt drive TT owners, or anyone using or thinking of using a drive belt made from 1/2" mylar. The belt material of choice on these tables for several years has been the silver holographic mylar streamers from sources linked on the Teres and Galibier websites. This outperforms everything else we've tried but like anything it's not perfect - and we've now found something better.

One of the silver holographic mylar's assets can also become a liability. That metallic layer, when new, gives the belt exceptional "grip" on the platter and motor capstan. Minimal slippage on transients is one reason the material works so well. Unfortunately, that layer can wear over time, leaving a silvery gray residue and allowing performance to deteriorate. The only solution has been a good cleaning and a new belt. No big deal, but if there was a better or more stable belt Paul and I wanted to find it.

I'll spare you a recounting of our many experiments and jump to the good news: thanks to (yet another) brainstorm by my resident genius/partner, we've developed a belt that both performs better and lasts longer. I've held off posting until we were sure, but after 4 months of steady use Paul’s idea is still working perfectly. The only negative is that making this new belt takes an hour or more of work spread over two days, but to us it's worth the effort.


1. Cut a length of the silver holographic mylar tape sufficient for your TT, plus 3-4" extra.

2. Remove the silver metallic coating off the backside of the mylar. Paul used an acid etching cream popular with stained glass hobbyists to dissolve the metal - safe, quick and easy (use skin and eye protection).

3. Rinse thoroughly under running water, inspect to make sure you got all the silver off, wipe and hang to dry overnight.

4. Splice as normal to make a TT belt, making sure you tape on the OUTSIDE (which will be smoother than the now bare inside).

5. As always, the best splicing technique is to overlap the ends and cut on a 30-40 degree angle. Apply 1” video splicing tape (*not* tabs) across the belt at the *same* angle and trim away the excess.


Unlike any plain mylar ribbon you could easily buy, the silver holographic streamer has an ultra fine texture embossed on the back side of the *mylar* during manufacturing (*before* the metallic backing is applied). Once the silver layer is applied you can't see this texture, but that's what diffracts light like a million tiny prisms to produce the shimmery rainbow effect. Stripping the metal backing away exposes this texture, which becomes the contact surface of your new belt.

Paul realized this texture must exist and then hypothesized that using it for the working side of a TT belt might provide more “grip” on the platter rim and motor capstan than either plain mylar (which is extremely smooth) or the metallic backing. He was right. This belt produces more lifelike dynamics, both macro- and micro-, than even a brand new silver holographic belt - which heretofore was the best.


Removing the metallic backing exposes bare mylar, which is much sturdier than that fine layer of metal. Under normal use and assuming no accidents, one of these belts should last many, many months, perhaps years, while delivering consistent performance. Ours is going into its fifth month with few visible and no audible signs of wear.

Different motor capstan materials might interact with this belt differently, but I urge anyone with a compatible table to give this a try. Like all our favorite little tweaks, we'd find it hard to go back.


1. Clean any silver/grey residue from your old belt off the motor capstan and platter before mounting the new belt.

2. As many of us have learned, the more inelastic the belt, the more critical motor leveling becomes. That is truer than ever with this new belt. Getting the motor set just right is touchy. Take care that your new belt is riding level in the center of the capstan before you start to play. You don't want it sliding up or down and mangling itself.

3. Motor distancing is also more critical than ever. Since this belt will not slip *or* stretch, tension must be perfect. The right amount is just shy of the tension that would tilt the motor off its feet.

4. Depending on your climate, the belt can build up static potential during use. Not enough to spark, but more than enough to attract airborne dust. I dust the belt's inside with my CF brush after each side before stopping the platter.

5. With this or any belt, always start your platter spinning with a helping push. Just pressing the motor's ON button creates lots of belt-wearing friction as the rapidly spinning motor tries to drag that heavy platter up to speed.

It all sounds like a pain, and it is! But the sonic and longevity results are worth the effort.


I just noticed the question at the end of your last post. The LP I described above (which Paul calls my "la-dee-dah record") is this one:

‘Les Plaisirs de la Renaissance’ (Harmonia Mundi, HMU 963)

There are many such recordings on the (French) Harmonia Mundi label. Arthur Salvatore's LP lists include many such in the Early Music catagory. We get ours from ebay, including some from European ebay sites/sellers. Prices are usually low (not a big market) and vinyl condition is usually perfect or nearly so.
Hi Doug!!
This Thread is invaluable. I hope you are still going to read this even though its an old thread. I used a single Mylar belt that Chris Brady sent to me 10 years ago until now! How crazy is that? I think its time for a new belt since my Teres 255 won't keep good timing and the motor is hunting for the proper speed on occasion. Only thing is, I can't for the life of me locate 1/2" Mylar streamers / tape...all the old links to buy this product has expired and Google brings up everything but the proper product. any advice on that? is there a place where i could buy ready "belts"? Best regards and thanks for this great informative thread.
Try here:


You might want to try cleaning the circumference of the platter as well as the belt itself. For the platter, distilled water with a microfiber cloth works well; for the belt, I use 95% isopropyl alcohol. Allow both to dry thoroughly. You'll get copious amounts of residue from both, especially if the pulley is brass which tends to shed material slowly over time.
I just stumbled upon this thread last week after a bit of a hiatus from audio. I made a new etched belt this past weekend, cleaned platter and motor pulley with alcohol wipes and played around a bit with belt tension to find the highest speed.
The improvement this has made just blows me away, as others have said the detail and dynamics are greatly improved along with the pace and rhythm.

Huge thanks to Doug and Paul for discovering and sharing this tweak.
Dave4u and Andirocks,

Just noticed your posts. Glad this tweak works well for you, as it does for most everyone who's tried it. Enjoy!

... and a belated thanks to Richard (Palasr) for posting that new source for holographic mylar tape.
