    AR 302 vs. ADS 710/810/980? (Bought a pair of L810-IIs)

    My ears are on the gradual decline, so I have been looking for some easier listening 3 ways for my listening room - I already own AR 302s with awesome steel stands but they are stored out of state. I have been very pleased with ADS 910 in my family room system here, and see 810s and others...

    Denon PMA-S1 (+DCD-S1)

    So, I impulse-bought a Denon PMA-S1 on eBay after playing with their current top-end integrated amps on a trip to Japan. It is an interesting beast. Very resolving, not glassy, more like a good (low distortion) tube amp but with fast bass. Weighs like 60 lbs. I'm not sure I could distinguish it...

    ADS 910 ... Very pleased, but need guidance...

    I am in the process of setting up an ~80s vintage system for my ~80s vintage family room. I just got a pair of ADS 910 off Craigslist (plus a fortuitous but non-working Hitachi HCA-8300 and HMA-8300!). They sound good, have some problems with the internal cable (needs to be tweaked a bit - maybe...

    Quad 34 (cake) for my 34th birthday...

    Hello everyone! Sorry, I've not been here for some time now, but I wanted to share... Every year, my wife has made me a vintage hifi themed birthday cake. This year it is a Quad 34 (in the original brown color). I own a Quad 44, but I'm not yet old enough to deserve the cake... Here's a...

    Denon DP59l (cake)

    So, for my birthday this year, my wife made me a Denon DP59l cake. It is approximately to scale, and even has a sugar-glass dustcover! :D It nicely follows last year's Mac 30 and 2011's Citation II cakes.

    Can anyone confirm that this Lorenz tweeter is LPH65?

    I'm a bit annoyed that one of the tweeters in my Lorenz S-1288 IIs is open-circuit. Can anyone confirm that these are the same as the LPH65? I'm hoping that all of the similar-looking Lorenz tweeters might be the same, to make my shopping process a bit easier. They look the same to me (based...

    My wife found a mate for my single McIntosh MC30

    Picture attached... Believe it or not, it weighs about the same as my real one. Judging by the state of the kitchen, this was a pretty serious project. The tubes are made out of hard sugar (like lollipops) -- Except for the sticks that hold them up, and their wicks (they also function as...

    Can anyone provide identification? Look like Acoustats or equivalent? Guesses as to the components? http://money.cnn.com/galleries/2009/fortune/0911/gallery.steve_jobs_rare_photos.fortune/4.html Looks like Steve had his priorities straight... although I'd need a chair. :thmbsp:

    Electro-Voice SP12C coil resistance very high...

    Question for the speaker experts - I just got a pair of Electro-Voice speakers (look like Esquires but with SP12Cs), but one SP12C is not producing sound and is testing at ~40 ohm coil resistance. The other seems correct at ~5.9R. I'm guessing that's bad ;) Is this cheaply repairable or...

    Dumbest Question Ever? Turning a Dual upside-down.

    I want to lube my Dual 1019, since the motor has developed a slight noise. Unfortunately, I have no idea how to safely turn it upside down. It can't sit sideways due to the shape of the base. I can support the base and then let it hang from the suspension springs. Or I can attempt to find a...

    Citation II meets HP8903

    Swung by Bricktop's place last night, but also brought my Citation II over for some measurements. The amp is rebuilt with a mix of McShane and jon_s parts. Power supply uses McShane favorite 820uF for the doubler caps, 500uF for the reservoir cap (to keep it from bouncing on transients)...

    White Oxidation on Yellowy-Rainbowy metal plating?

    Is it toxic? :headscrat I got some nice military teflon loktal sockets from eBay, all still sealed, but the metal plates show signs of funny corrosion. There is powdery material in some areas against the yellowy-rainbowy metal of the mounting bracket. Just curious what I'm working with...

    GE Stereo Classic Restoration...

    Welp, I'm done, minus a knob. But I'm not gonna show pics until tomorrow, since I haven't taken 'em yet. (updated!) Inspired by Bricktop, I got a MS-4010 6973 amp on eBay a few weeks ago. It came with the mono AM/FM tuner (still screwed to original cardboard packing sheet), and all was in...

    Matching my MC30... help?

    So, I have been trying somewhat desperately to find a mate for my MC30! I have wanted ads posted all over the place. Mine is a 9E-something serial number, with no extra bias tap on the power transformer (transformers 150B and 152B). I found another 9E but the numbers on the transformers were...

    Bogen DB230A?

    I just got one of these off eBay -- the one that uses 6AV5GA sweep tubes. It seems to be a bit of an "oddball" amp (possibly a sleeper?), and I figured it would be fun to restore. ... SO, does anyone have a pdf or gif schematic? :scratch2: images.google hasn't been helpful for this one...

    Just got a Citation II...

    My friend has nominated it (endearingly) the "Shitation" :banana: -- It's spray-painted (partially) in silver Rustoleum (it had been sanded first, due to serious chassis rust), with resistors sticking out of the top to be used as bias test points. But the chassis is solid, and the electricals...
