Still didn´t get any further as the pictures show in this thread. My new job brings lot of learning new things with it. So not enough time to get to the machine shop.

Have you powered on and tested both sides of the amplifier yet? The more you do to this amp the more you will have to take apart if you discover an issue later on. There have been several times I have put a MS amp all the way back together just to discover something wrong with it which I then needed to take it back apart to fix. Save yourself the effort and test it now.

Same place as a few months ago. It is a prime example of testing as you go. I had half all the way together when I discovered a glitch in it, and I am too uninterested in taking it all the way back apart to fix the glitch, so for now it just sits in the corner.

I already load tested both sides! I tested with subs, mids and tweets just to make sure it doesn´t have issues in a certain frequency range. I tested with testtones and music. All that´s leftover to do is to test it how much i really can get out of it

Did you test it before or after you spread thermal paste all over the heatsink insulator strips?

Did you test the amp for any current draw when the remote turn on is not active?

The only reason I ask, is silver thermal paste is slightly conductive. You have created a very high resistance short between all the transistors on each of the insulator strips. I am very confident your amp will not be reliable due to this. Either your power supply will fail, or at the bare minimum, noise will slowly develop in one or more channels. You might even end up with a fire, but I doubt it.

Since you first posted the photos of your coated strips in this thread I have been looking at different thermal pastes as time permits. I have concluded none of them are completely non-conductive. If you are building this amp as a showpieces to place on the shelf, then you could leave the paste there. However, if you plan to install the amp, or if you ever wish to sell it, I highly suggest you remove all the excess paste, or you will have problems.

I´ll remove the thermal paste that is too much as i´m going to use this amp. Thanks for the info eric.

I just had a few minutes today and took a few pic´s building the shroud!
Unfortunally my batterie died and i couldn´t take pic´s of the finished product

Today i had a chance and worked on my shroud again!

Now i only need to smoothen the surface and it is ready for paint

I also testfitted the shroud and put it into my BMW´s trunk to give everybody an idea how big that thing is.

Post by **joerg** » Mon Mar 29, 2010 10:16 am

Today i used some bondo and sandpaper to get a real smooth surface. The welding edges are gone. Ready for paint now. More to come tomorrow

Post by **joerg** » Mon Mar 29, 2010 10:24 am

My favorite looking PG amps are the plain white ones - understated, subtle, classy... everything glitter, decals and themes are not. But that's just me

how will you mix the flake in with the clear coat joerg?
coming from can- i am curious...thats all?!

I would love to coat that F&^%$R i like simple-straight forward stuff like that- they always come out pretty good- BUT shipping is a bitch i know- Do you!
Curious to know and see final results though- especially about the flake in with the clear,... coming from can?...(?)

U are thinking way to complicated Matt! I just took a saltshaker!

It might not 100% perfect and even but i can tell it looks awesome! Will ket the paint dry and post pics tomorrow

Post by **joerg** » Tue Mar 30, 2010 10:04 am

I couldn´t wait with taking pictures until tomorrow

I blacked out the inside of the shroud. Then i painted the outside gold metalic! (what else to use for a Phoenix Gold item!)

After that i used a saltshaker put both sorts of glitter in it and mixed them a little! The i applied the glitter onto the shroud. After that a layer of clearcoat and voiala...

Nice one J

I have a suggestion for you.......instead of the bussbar across.

why not , and tell me if I am thinking a bit too much , take 3 caps and put them in a line on each side of the amps, will make it look like both amps share a huuuuge cap bank in the middle of the boards.

Joerg
I don't know if its the pics but i will have to wait to see the finished product
looks like the paint is flat just not a fan yet of the color

Post by **joerg** » Tue Mar 30, 2010 11:19 am

Sounds nice but where to put the lighting then? Now it´s under the bussbar to have some descent indirect light.

I'd try a layer of Nitromors
