    The Mastering Labs XOs are what the big boys tended to use.

    Now, in all seriousness, I've no idea which XOs either of the above control rooms were usin' with their Duplexes :-P

    There were also other monitors in use -- like the wonderful RCA LC-1As... but I won't be in a position to be affordin' a pair of those in my lifetime I don't think...

    Plus the refrigerator-styled RCA enclosures were real cool, man.

    Speaking of LRE...

    Decided I was going to offer this one up at the Westford antique radio fleamarket this coming weekend, so I took a few photos to remember it by...

    This is another one I'll offer up to the flea market deities. Heathkit AR-19.

    The AR-19 was replaced (rather quickly) with the AR-1302. I never quite understood that whole deal -- maybe some design flaw with the former that was fixed in the latter (?)

    Note for these Heathkits and the LRE posted earlier, we're in the pre FTC 1974 spec requirements for home stereo equipment power output claims :- )

    So I cleaned her up and Deoxit as best I could and hauled her over
    to a keyboard playing friends house. Plugged her in and besides
    having some stranges noises on somes channels and needing the
    pots cleaned, it was quieter than the amp he's using.
    Needless to say, he was very happy to take it off my hands. :)
    well not hi-fi per se but I just picked up this mixer amp;

    I have to admit I heard the potential there and it put
    a smile on my face. Had it set on "2" and the
    Yamaha's were cranking!

    This might not count but it is vintage and for the time fairly HiFi. This is my dad's photo squadron, Yokota Air Base taken 1952. 2nd Photographic Squadron, Photographic and Air Charting Service. Dad is 4th from the right, front row. He would have been 21 or 22 here.

    Thanks Mark. From an A/V standpoint they had some pretty cool stuff. Any idea what the box with the angled front might be? There is not enough resolution in the original photo to zoom in far enough to get the brand name of the tape machine.

    just picked up some stuff tonight for a "all you can carry"
    price. Kenwood ka-7100, SAE P102 pre and A502 amp, Sansui A710
    Kenwood is hooked up and playing. The controls are due for a serious cleaning

    I don't know -- reminds me of a signal generator but could be most anything. I've been resisting the temptation to try to suss out the ID of the recorder ;- )

    The KA-7100 is a pretty nice amplifier -- as you probably know, it has a slightly low-rent variation of a true dual-mono power supply. It has only one power transformer, but the PT has dual secondary windings, and the entire power supply downstream of the PT is split for the two channels. Note the four P/S filter capacitors in the photo below.

    Are the 'knobs' on the toggle switches on the left side of yours anodized, colored with markers, or painted? They're... interesting.

    Oh, I just noticed that some of the knobs don't appear to be the originals... in fact, they look like knobs from one of the later Kenwood integrateds. Interesting.
    Here's what a bone-stock KA-7100 looked like (note the different looking knobs on the right side of the amp).

    ... and I am envious of those STAX earspeakers! :- )

    I use a pair to test with. The transformer box can handle a lot of abuse that speakers can't. I have a nicer pair for real listening.
    It appears to be paint on the switch knobs. As far as the rest go, at least they match.
    It's working pretty good right now. But it's filthy inside.
    The same guy had a Sansui au-717 I missed getting by 10 minutes.
    $20 for an au-717 would of made my day.

    I would call using STAX electrets as bench test mules luxurious! :- ) I am now doubly envious.
    They're wonderful "earspeakers", they really are.

    Yes the carpet does match the drapes... umm, I mean... the replacement knobs do all match, which is a plus. In fact, I'd say that they're more elegant looking than the rather chunky originals. The volume control knob on your KA-7100 does appear to be original, tho'.


    Yes, 20 for an AU-717 would be a bit of a... scroe (as they say on a certain other hifi site).

    I'd like to have an AU-717; much nicer than average SS integrated amplifier of its time. Fully "dual mono" P/S in those rascals, too. And built like a brick privy, fer shure.

    The au-717 or the au-719 are on my short list of must haves.
    I drove over there for the au717, but the ka-7100 and SAE stuff was
    certainly ok.

    I have a Kenwood KA-7300 which seems to have a more dual mono construction? A very nice sounding unit if ONLY it would continue to start up! lol A tech has looked at this and assures me that there is NOTHING wrong, but every time I get it back it takes longer and longer for the relays to kick in and then finally NOTHING happens and there is no sound! Don't really know what to do when the experts don't "believe" me. It sounds VERY VERY nice with my Monitor 7s-when working!

    I also have a AU-517 (in the shop for its phono section) that sounds a tad "dark" by comparison. I suppose a recap is in order but that's a lot of coin and time, and few around here are willing to entertain the "fantasies" of a vintage boy or girl?

    I like the old Kenwood gear and was looking for something like this before settling with the Yamaha CA-1000 (if that can be considered settling).

    There was a little bar back home in Missouri where the owner would paint switches and buttons on the audio gear so the employees knew which buttons to touch and which ones to leave alone. The place did great deli food at lunch and half the time we would go in and there would be no music. The little lady would have not been paying attention and hit the button next to the power button and would not be able to figure it out.

    Painting the power on button Red made it easy for her.

    You need to learn to use a DMM, cnh! :- )

    Something's definitely not right -- possibly a power supply issue (generally the delay 'waits' for stabilization of proper operating voltages), could be a tired component in the amplifier circuitry (capacitor, resistor, or an 'active' component, i.e., transistor/IC), but maybe as simple as the relay(s) is/are failing.

    The protection boards sometimes have issues- or there's issues with the power supply voltage- a quick trip to audiokarma will yield common issues with
    those units. Those guys have a lot of crash and burn with old gear.

    Cnh who is your tech now ? I heard Pete wasnt open OR was only taking appt now ???? Electronics & More did my rt909 & he said he rather not work on anything that wasnt band related. He told me Sansui & Pioneers he would do for me. Its getting hard to find audio techs up here

    Gonna give it a try tomorrow. Ive heard the receivers & to me they sound kind between Onkyo & Pioneer vintage. Not too bad imo. Small 22wpc i think

    Picked up another 2252 Marantz also with the balance slider also. Not the B. Gonna try the Klipsch on the Nikko then the Marantz. Kinda hoping the Nikko does well. Its small in size & perfect for the area i need to fill

    The Marantz 2252 is a pretty good receiver. I also had a Nikko receiver
    for a while, also good. My guess they both have good sound, but different
    in how they get there. You'll end up keeping both!!!
