Looks good Wardsweb

Do you use something to seal the glassbead in,
so it doesn't get on to the platter?

I used heavy plastic foil on my box ( gone now, sigh )
but better things may be available ?
Thinking of static electrisity.

cheers

I've put nothing over the glass beads (feels more like liguid silk it's so fine). I have seen people cut strips of foam that fill the gap between the top plate and the sides of the box. I'm going to leave mine open for now and see how it does.

Looks great,
Can you tell if this improved/changed the sound of Pega P3.
BTW what cartridge do you use with P3?

Thanks
Sergey

Presently using a Audio Note IQ-2. This is a very high output (5mV) cart. Thus I was picking up some rumble I had not heard before. The new platform has cured that problem and added a quiter overall background. It'a hard to put into words but the imaging is cleaner, don't know to call it crisper or more detailed, but regardless it's better.

To Wardsweb,
Your Foreplay looks absolutely stunning.
The top and rear metal panels look like polished steel but you saying its aluminum. Did you have them chrome plated or what.
Let me know.

Thanks

It's just polished 6061 aluminum plate. Since completing my Paramours, I have refinished the Foreplay in red mahogany to match.

Wardsweb,
It is my understanding that aluminum surface will oxidize overtime and it would look rather dark. Also, all fingerprints would stay on clear polished aluminum surface and also oxidize.
What do you think?

I don't know much about metals, I'm Electrical Engineer myself.
What's the difference between 6061 aluminum and other aluminum types?

Thanks
Sergey

Hi,

While I'm certainly no expert on these Alu materials, once polished, can't one varnish it with a translucent kind of stuff?

Cheers,

6061 has 1.0 % magnesium and .6% silicon. This gives it a good tensile strength for machining , but major advantage is very high resistance to corrosion. For this reason, among others, it is used in aircafts and indy cars. I only apply a coat of car wax over the finished surface. I can then replolish by hand if it gets scratched. If you are going to spray a clear finish over polished metal, do not use arylic, it will crystalize over time and/or turn yellow. If you must paint , use laquer or clear anodize.
