    Hi all!

    I just bought a pair of ADS L810 speakers, which I've heard are some of the best speakers from that time (late 70's) into the early 80's. I was super excited to test them out and hooked them up and I was very underwhelmed by the treble. The treble was awfully muffled.

    by iMic
    Hi,

    Back after a long hiatus with some old power supplies that need repairing. I've recently picked up a couple of 386SX systems, two 486DX systems, a SiliconGraphics Indy and an iMac G3 that either have verified leaking capacitors in their power supplies, or are likely to in the near future. For the sake of simplicity, instead of tackling all at once, I'm starting with the 386's and one of the 486's.


    The 386's power supplies are Seasonic SS4040A's, with caps that are visibly leaking, and 9 replacement caps per unit are required. Most appear to be from the Rubycon...
