Default KSA-100 Power Supply

Started on putting the Power Supply components into the case. Boy, it is HEAVY. Now when I go to second hand stores and see used amplifiers, I just pick it up to see if it's heavy. HA-HA.

Wow, when you see it in this perspective those transformers are really huge! I like them. Will that become the PSU-box for the KSA David?

Haha, you better prepare, it will only get heavier Mine is almost like a boat anchor when lifting it up. But hey, great excuse to quit my fitness subscription

See it from the bright side David after lifting the KSA a dozen of times you will gain the same muscles like Arnold Schwarzenegger had in his glory days

Well going to sleep now, but, to quote Arnold 'I'll be back'

I paid $65.00 US for each. They weigh close to 22 pounds US. The website

DIYCable.com : Intro Home Exodus/Hypex Amps Amp Parts

for the specs. They are used in their bass amplifiers.

I hope so. It's not too much? My growing muscles are over. I want to use my brains for now for a change and let electronics do the work. It was really cute how the soft-start had a tiny jumper from PP to 220v and I had to resolder the little jumper to convert the soft-start to 110volts. The PSU-Box is very tight with those transformers, so I created a bridge across the inner-box so I can attached the terminals, soft-start and maybe the bridges. Tomorrow, I will go to the scrap metal yard to find some copper plates to run across the neg poles of the can-capacitors. Sleep well and have a good day, David

Default KSA-100 PSU

I fabricated a bar across across the top of the PSU.

Any other suggestions? Kaplaars, I wish I had a boat to attach an anchor. My dream is to own a very small sail boat to sail on the Lake Michigan. During the summer, especially on the 4th of July, our Independence Day, if you have a boat of any sort, you can anchor near the shores of the down town area at night and watch the fire works. I will have an extra 13v/1amp secondary and was thinking I could put a small computer fan atop the PSU.

Hi Spurlte

Nice toroidal transformers you have there

Where did you get those beauties?

Will you use NTC for inrush current delay?

And don't forget small values decoupling capacitors in the PSU ...

Best regards, Andrej
