Minimum recommended amplification requirements and amplifier matching
I like to run tube amps, and while 30 watts or so will make tunes on a speaker of 90 db, I think you will need more power. If it were my room, there would be no doubt. My speakers are 98 db and 16 ohms, and I really think 30 watts is about the min... 
What does moving from a 150 watt amp to a 400 watt amp get you?
I’ve seen others say that these speakers need to be driven by 400 Watts to get them to sound their best. If you really need 400 watts to make a speaker work, in a nutshell the efficiency of the speaker is borderline criminal. The reason why is sim... 
Ps Audio BHK preamp Vs ARC best preamps
Paul McGowan said he had the same experience and that he couldn't explain it either.@tomcy6 The explanation is simple- interconnect cables contribute to the system sound if not properly controlled. A raw passive volume control puts a series resis... 
Inexpensive Tube Amps
I have a pair of Mirage OM 10 Towers that are 6 ohm and 91 db sensitivity.  Should not pose a problem for any of these.  Also have a pair of Castle Conway 3 Towers that are 8 ohm and at least 88 db sensitivity.  @will62 None of these amps make ... 
Please give me advice about an ARC VT 200 amp
@noromance  The technique I wrote about has been around for many decades as you can see from the post prior to this.When the bulb is lit, the voltage drop is all on the bulb. This can happen if the filter caps are shorted or drawing current as the... 
Tandberg Unit needing some love
Why would it be? Electronics from that age is usually designed with many discrete and freely available components. If one of those has failed, it will be easy to repair.+1 
Recommendation Amplifier to match with Shindo Aurieges for Devore Fidelity Nines
That speaker is very friendly to tubes, but you do need a bit of power. Our M-60s drive them quite well; so you have a wide range of tube amps to work with! 
New idler for Garrard 401
That is the oldest website ever! 1998 and last updated in 2002.Yeah- looks like it was written in Crayolawrite 1.0. But their product is excellent. I would consider auditioning one of their idlers as they are a whole heap less cash, and they liter... 
Brand new to vinyl: Help!
I can help too- we produced the world's first balanced line phono preamp.The advantage is that the interconnect between the arm and cartridge does not contribute or rob anything from the sound of the system, unlike single-ended setups where the in... 
TT mats
SOTA Supermat is acrylic. Just like the awesome Goldmund mat. Good stuff, both of them.This statement is false. I can't say what SOTA is using now, but the Supermat to which Raul refers is not acrylic: I owned and still owns several mats almost al... 
Looking for amp advice (punk, rock & reggae edition)
So the fact that the speaker impedance is at its lowest in the midbass (4.2ohms at 118hz) and that I am not getting the mid bass I feel I should be getting is not related?Yes. As I mentioned earlier, the speaker is an easy load for a tube amp, a... 
Please give me advice about an ARC VT 200 amp
@noromance , The technique I offered works just as well and is a lot cheaper. Based on your post I suspect you didn’t read my post all the way through. 
New idler for Garrard 401
If you have an older idler, they can be refurbished by Russell Industries for about $40.00. They do an excellent job and can also refurbish capstan idlers for Ampex and other tape machines. They bought out the old Projector-Recorder Belt Company w... 
Best tube amp for Wilson Watt/Puppy
George, you know this is a zombie thread, right? 
Looking for amp advice (punk, rock & reggae edition)
I think its current as a large section of the impedance curve is closer to 4ohm than 8 ohm.Current is not the issue here. If the amp can make the power, the current is present. This is because power cannot exist without current. The power formula ...
