1990 Carrier Air Conditioner Circuit Board

Night and day difference between this and an all circuit board pre... nice and mellow even before it hits the DAW.

I decided to retire my first warthog throttle after having to replace the main circuit board and noticing how much wear the internals have suffered over the years of daily use. The original still operates well, but it is getting pretty loose in its advance age. These units are built like a bag of hammers, robust and tough. I do really appreciate the upgrade to the slew control over the old design.

This is a great tripod! I've already used it for both a product shoot (printed circuit board) and test equipment screens at work, and took photos of the family at Thanksgiving. The latches are stiff, but should insure a good sturdy support for my camera. The horizontal arm worked great for Macro work. I also have their monopod, a great 'pod for my walks.

I bought this for providing audio during film shoots. The design seems really tough, all metal construction. Looks like something that could be dropped on the floor a few times and still keep working. Good clean amps, but not a huge amount of gain. A few very minor critiques: uses AAA batteries ( I would have preferred AA as everything else on set uses AA), case is easy to open with ballpoint pin but can be put on backwards and then does not quite lock when closed (either make it impossible to put on backwards or it should lock when on backwards), two internal circuit board switches (mono/stereo and low/high power mode) the low/high power switch is hidden and not easily visible. It is a little awkward to have to access circuit board switches to adjust these settings. Overall very happy with the product.

This is a solid piece of equipment. It is slightly difficult to install the clip without damaging the circuit board inside, but definitely not impossible.

Brother Toner works well in Brother printers; however, OTC generic brands at a much reduced price also work well. That said, there is one application that one requires original Brother toner. That is printing on blue transfer sheets for making printed circuit board etching masks. In this process, one inserts a sheet of blue transfer paper in the Brother printer, and prints the line and land pattern 1:1 scale, on the blue transfer, and then irons the transfer on copper printed circuit board at 300 F. This transfer process does NOT work with generic toner because characteristics of toner fusion and density differ from Brother. Transferred generic media is thin (not dense) and adheres poorly, whereas Brother toner works wonderfully.

We have it for everything, Air-Conditioner panel control, Land line phone, Toys Etc',

This speakerphone is very clear on both ends. Was able to hear the other person speaking clearly even when my portable air conditioner was running in the room.

As always B&H was very quick to send the package out and it was what we ordered no problem. Our only problem is that the air conditioner is apparently too loud for even this windscreen to totally block the noise. It does a much better job but the mic is apparently extremely sensitive to all sound.

I got this because during the hot months I can't run my air conditioner and computer at the same time due to neighborhood brownouts. If I turn the air conditioner off the computer overheats. This covers the outtages so I can work in comfort without unexpectedly rebooting every few minutes. Thanks!
