But I've been unable to find another example that has an identical back panel to this one. I'm looking for insight on whether this may be an...

    Receiver wattage for McIntosh ML-10C speakers?

    I recently inherited a fully functional Pioneer SX-535 receiver (rated 20wpc). Will running this receiver with McIntosh ML-10C speakers cause excessive clipping even if I just listen at low-to-moderate volume in a smaller room? I also have an Onkyo TX-2500 MkII rated at 27wpc but currently...

    The MAC 1900 Volume & Balance Pot Solution

    I had purchased a MAC 1900 that cosmetically was very nice, but internally was an absolute disaster. Took on this project and I hope that some of the work I did might help others. First off, I replaced some of the key transistors (orange/yellow dot, flying saucers, etc.) and changed all the...

    This post is a long shot, but here goes! Given that there was only little over 6,000 MQ-101 units made originally, it's over 45 years since they were last produced, probably only a small portion of the units that remain in use, and a very few being operated in European mains voltage areas...

The pdf version in the AK Database is good as far as it goes but it appears to be missing front matter and sections 1 through 3. Any help would be greatly appreciated.
