    New to me McCormack DNA-225

    So I just got a McCormack DNA-225 (Platinum + level upgrades from Smcaudio) in the house. Hooked it up last night for a listen. I'm really impressed! My pre is a CJ PV-12 and I am driving some ADS-L1290's. I had Richard So refurbish the tweets, mids and crossovers so they are as close to spec...

    Bedini-Strelioff Model 1 amplifier hum

    I acquired a Bedini-Strelioff amp at an estate sale. It was missing a few of the fuse holders, but aside from that, it looked pretty good. After obtaining some replacement holders, I was able to power the amp up. The sound is excellent, except for the hum generated by the amp. Part of the hum...

    Not sure if this will help someone with an Akai AA-6000

    Hi, l have just been working on a Akai AA-6000 from around 1971. It had a low level hum in the left channel with volume between 1/4 and 3/4. I narrowed the noise down to the pre amp/tone section as l desoldered the inputs at the LH main amp board and all was quiet with headphones. The unit was...

Now I've added a Carver M-1.5 power amp to power front L and R in the setup. I have the Carver connected to the switched outlet on the...

    Recommendations for amp repair?

    Hello folks, I use an old integrated amp (Marantz 1060). While it still sounds pretty good to me, I think it might be time to get the capacitors replaced. I often hear dust or scratchiness when I turn the volume knob; and there's a sustained hum that I hear when there's no music. I'm not handy...

    Electrocompaniet

    Okay, I've inherited, at no cost, a pristine, vintage, Electrocompaniet amplifier. However, I was told there is a hum in one channel and that an estimate of $500 for the repair had been given by someone. Unfortunately, that is all I know, and the owner is no longer available to question. Anyway...
