Finally, My Amp.

Discussion in 'Amps and Cabs [BG]' started by The Golden Boy, Jul 20, 2005.

  1. It wasn't the nicest day, but I was off work, and my amp was home instead of the studio.


    I love the way this amp sounds, I just think there's a better way of cooling it off. I've had issues in the past about the amp overheating.

    This view is from the front. Air is passively drawn in through the grate at the top center. The two large rectangles are the heat sinks, and the fan is just to the right. The air is blown from the inside of the amp to the left and ostensibly out the grate on the left side of the amp.

    My main problems are:
    First, there's a space between the end of the heat sink and the ventilation grate. That's a lot of hot air that will get circulated back into the amp, even if most of the air gets pushed out. You'll notice there is no fan to force air in nor draw air out of the amp. In fact, there is not a ventillation grate in the cover of the amp.

    Secondly, the amp is designed and expected to be placed in a rack. There's less than an inch between the side of the amp and the wall of the rack. That doesn't leave a lot of space for air to get passively pushed out of the amp and leaves nowhere for the hot air to go. Except into the rack and get drawn back into the amp.

    Thanks to the folks here, I was able to mount a fan ($15 fan from Radio Shack and a $2 plug for the end) to the upper rail of the rack to pull the hot air out of the amp. This has worked like a charm! But notice I still carry spare fuses taped to the left wall of the amp!

    And a Close up of the fan.

    For anyone that's had overheating problems in a rack mounted unit- seriously, it's less than $30 total and maybe an hours worth of your time to install a fan. You need a drill, a bit, 2 screws and 2 nuts, the fan and a plug to connect the power wires to. (I also taped the power wires to the ceiling of the rack) I'm not too concerned about noise, as I'm in a rock band, but I'm sure there are smaller or quieter fans than the cheap one I got.

    That took a really, really long time to get these pictures taken... :smug:

    Yep, but fortunately I haven't had heating problems at all with my GK. But I did get a rack with rear rails special order JUST IN CASE I needed to install an extra ventillation system.

    Thats a really handy idea Golden Boy has.

    I think the stickers are a cute little touch :)

    Nice work bro. Looks good. TB is an awesome resource for issues like this. Wth the pictures you added, now anyone can do this very easily.

  5. I was in a metal band at the time. :smug: I actually hate putting stickers on stuff, but you have to keep your black SKB case identifiable among all the other similar racks. I just went stupid with stickers. :D

    It really is easy, just measure several times and drill once. :p
  6. Goldy, what are all the numbers meaning on the masking tape??

    Is that like clock faces so you know where to set the knobs?

    I was just going to ask that :)
  8. Exactly!

    Notice the semi-parametric EQ has concentric knobs. Using a clock time hand position thing, I consider the inside knob the hour and the outside knob the minute.

    They're ballpark figures- :smug:
  9. Hey! Nobody's mentioned the "I'm A Winner" plaque covering the $WR logo!

    I noticed that, and didn't say anything because it looks better :)
  11. Some might remember me bitching about the myriad of problems I had with this amp. You also may not notice the power LED, it doesn't show but it's blue- because the stock original red one was either faulty or had a cold solder joint.

    Yes, I was far too lazy to drag the cab onto the deck.
