    Was walking by that shelf and shot these with my phone. Maybe I should invite everybody to a garage sale. I'm getting old, been years since I touched some of this stuff.Some of the pics you need to click to open up. The plywood is birch, I bought as cut offs from a local mill. I have more than a lifetime supply. Just under 2 ft x 4 ft.

    So, you're saying that you'll accept plywood scraps for trade? That's awesome! Lol

    Are the Altec 9444B pretty quiet? I think I might like those. Thanks again, old guy!

    9444bs are quiet, as long as they're in another room.
    I'm pretty sure the fan runs continually.

    I can understand that. I guess once the music is playing it's probably ok...?

    LOL. I have not looked at the 9440 fans. I know you can buy speed controls for fans, might be able to slow them down. Not like you will be running at full power.
    Same will likely be true of any amp with fans. Which is most nowadays.

    Paid cash for the birch. It's around 70 a sheet here. I bought quarter sheets for 5 bucks.

    Actually according to Altec the fans are two speed thermostatically controlled.

    I suspect that means "Runs on low, kicks to high when warm. There are ways to deal with fans.

    These are from a music studio in a local university. One of my guys put them in. I didn't see howthey used them.

    Are they functionally ok? And where would they be shipping from?

    There are many companies involved in electronics design. I think that this is a fairly popular branch, because people like not only the internal characteristics, but also the appearance of the gadget, whatever it is.
    Check tronicszone is an electronic product design company that has been doing this for a very long time and has a lot of feedback. So you can contact them and you won't regret it.
