    Or...some of you guys could organize a group buy and place an order for boards. I emailed Exojam the DesignSpark CAD file the other day. ;)

    So far I have not had a chance to dig into that much but when you just load the file you can see how very neat coolidge56 has all the boards layed out in a very organized manner.

    Once I get some more time I will play with it more, I just need to remember to never save any changes I make messing around or just have a master copy in another location.

    Damn coolidge56, you must have done something very right to get niekeel interested.

    I wish I could join in but the funds are not available.

    The board may look good, but how it sounds remains to be seen.
    You see, the sound of a tube amp is largely the layout. There is a lot more going on than what is on the schematic.
    So just because you laid out parts neatly, side by side, does not mean it's going to sound good.

    Wiring up turret boards is my fave part of building an amp :)

    Please provide us your explanation on how this setup will sound of the amp?

    I and others would be interested your explanation.

    I for one cannot see how his setup will have any bearing on the sound quality.

    I will give you 1 example:
    If 2 audio coupling caps are placed side by side, they radiate into each other. And what is essentially between these 2 caps "is" a third capacitor.
    The air space between the 2 caps is forming another cap, through which audio may travel...

    I call BS on this nonsense. Unless you are prepared to say Metropoulos Amps has been doing it wrong all these years?

    I never said anybody was doing it wrong. That was not the point.
    Also what I just told you is the whole key to building the best sounding amp possible. It is certainly not nonsense.

    I LOVE how clean your board is, its spotless! As I work down the board soldering I shield everything except the component I'm working on with wax paper and blue painters tape. This keeps the solder spatter mess off the board and components.

    A few of you have expressed interest in doing a group buy of these boards. How about I just send you one for free?

    Before you answer a couple of things. I'll only ship to the U.S. sorry but I don't want to hassle with international shipping. I'm donating 5 of the 10 boards I ordered so that's how many are available. Consider that these boards won't fit some off the shelf chassis you would need to modify to fit the board mounting hole locations.

    Since Exojam, coldengray, and neikeel expressed an interest in a group buy they have first dibs.

    I wish I could take one but I'm not a builder, I love what you've done with the one you put together, I'm looking forward to you getting this amp built and show off a demo! :yesway:

    Looks like there’ll be some lucky people over on your side.
    Looking forward to the completed build.
