    I like the multi use bench. Especially the RCBS Rock Chucker! Or is it the Rock Crusher?

    Really? Mine have been great. How did you isolate it to being the P/S?

    My 36 amp MW that's 4 years old shows up on my IC 7300's scope, and can be heard on the lower HF Bands. The fan is also noisy. I only use it for my Yaesu 2900 running 75 watts. It's all good though. Its a tank, and a darn good one. In the past 4 years there have been many things hooked up to this PS, and it has never failed. I do keep it clean. I use a separate PS to run the 7300, just to keep things as clean as I can.

    I just won't trust any switcher from now on. Just isn't worth it.

    Well after 4 1/2 years my MegaWatt 30/33 fan finally started to whine to the point I couldn't focus on my HF rig noise.



    and after I stuck in a small 60x60x25 fan as a temp fix that I bought new for a repeater project and was just laying around new.

    Factory fan is 15mm thick in case you need to know and has a 2 pin white connector and about 6" or wire.

    I've been using the same Megawatt PS for 9 years now - no issues, no hash, fan still same volume. Hard to believe how well it's held up, I was actually just looking at buying another one!

    Mine picked up a tick after about 5/6 years, but that was due to being in a dusty location. Some compressed air and a little lube and right as rain.

    got fan in today from MegaWatt and popped it in. All back to normal. Keeping my spare fan as a spare, back in the box it goes.
