| Restoring vintage H/K Citation 19 Power Amp @dgarretson I think Jim only does the Citation 2 and 5. | |
| Expanding questions about tubes in a preamp Gents, how the hell does adding damping rings change the sound of a tube. Nonsense! Answer: by reducing microphonics. The effect is easily measured and heard.But using a low microphonics tube is more effective yet. Installing dampers on them has t... | |
| New to preamp amp, turning on question Many preamps have a mute feature when turning on. This is to prevent thumps in the speaker.The usual procedure for any amp/preamp combo is to turn the preamp on first and let it sit for about 30 seconds prior to turning on the amp. This will insur... | |
| Restoring vintage H/K Citation 19 Power Amp Something this old will need new filter capacitors in the power supply. That is the source of the buzz (its a 'buzz' if its anything over 60Hz FWIW), and the reason its not there if you cycle it off.If the filter capacitors are not replaced, the p... | |
| 100W, 200W, or 300W? @eisenb11 If you can't clip your existing amp then possibly yes to a class A amplifier. High end is all about nuance!'Echoey' isn't good- that makes the room more lively and harder to enjoy at higher volumes. So you may find that once the treatme... | |
| arc reference 300's preamp ideas Is there any reason that you would get an ARC preamp- there are other balanced line tube preamps out there. The Ref series are some of their better sounding preamps though. | |
| my $686 stereo system, laugh if you want... @bottomsup One thing to look out for on equipment that old are the filter capacitors in the power supply. You got an amazing deal- someone clearly had no idea of what they were selling. But if a filter capacitor fails (and this stuff is old enoug... | |
| Finding the bad tube You'll need a known good tube. Swap it in, one tube at a time. If you hear an improvement, then you know that known good tube is helping.But you may have more than one bad tube- they have a way of going slowly downhill; at some point they can get ... | |
| Anyone Know Where I should Look to Figure Out This Hum? A *hum* is 60Hz *only*.A *buzz* is based usually on 120Hz but can be heard in the tweeter.So we might have a nomenclature issue. A ground loop would produce more of a buzz than a hum, at least in every case I've encountered!Lamm tech said they fou... | |
| 100W, 200W, or 300W? My room is a little smaller than yours: about 15x15x10 high. Sub is eventually on the TODO list to fill in the bottom end - but after amp and streamer upgrades.@eisenb11 If your room really is these dimensions then I don’t think you’re going to ne... | |
| Is Sub Gain Set&Forget Across Music Genres a Fallacy? I was just wondering if it is even possible to reach that level of simplicity and ease with one (ideally for me) or more subs after the initial calibration @kren0006 Of course is possible! The sub settings have nothing whatsoever to do with mu... | |
| Empire 698 turntable 'Circlip' is the expression, and yes they are a bit tricky. IIRC, the mount on the tower is slightly recessed, making it difficult for the circlip to come out on its own. Again IIRC, you should be able to extract it with a medium to small flat bla... | |
| Empire 698 turntable Are you sure that your 698 isn't just needing a bit of adjustment? The 'table is suspended by the springs which are fixed to the subchassis using wingnuts. The wingnuts are used to level the 'table.At any rate the springs are attached to their tow... | |
| The Audio Alto R101 : A special speaker for SET amplifiers and small acoustic spaces If you love tube based SET amplifiers or low power Solid State amplifiers (think Pass Labs XA-25) ***and*** have a relatively small acoustic space this might be a great speaker for your system.Emphasis added: the low sensitivity of this speaker ... | |
| Why do most phono preamps lack XLR input even thought cartridges are naturally balanced? @oldears If its not humming I would not worry, but I suspect there is no need for the 'drain' wire, as the preamp is likely electrically grounded via the ground connection of the AC power cord.We've been making DIN to XLR phono cables for decades... |
