ampllifier design The 6DJ8/6922 family of tubes, which includes the Russian 6H30 extension, are not designed for audio, and while quite linear, tend to have a microphonic signature that is considerably more pronounced than in other tubes designed for audio, like th... | |
Transient Attack and Amp Design Saki70, the difference between 8 and 4 ohms can be all that it takes; nearly every amplifier made will sound faster (as well as less bright, more natural) on a speaker of higher impedance. | |
Please suggest good balanced Preamp Tvad is absolutely correct without reservation. | |
Power Amps with High Current or High Damping Whatever is going on here, damping factor (which is over-rated) has little to do with it. The speaker has a moderate impedance without a lot of phase shift- a tube amplifier as commented in the reviews can work with it just fine. In fact you don't... | |
Tired of Problems with Tube Equipment Smeyers, FWIW, the 6C33 is a special case in the world of tube amplifiers. Unless the amplifier has custom sockets, the Russian or Chinese sockets that are commonly used are overheated during normal operation. The filament circuit is the part that... | |
Driving 1 ohm Rwwear, ESLs do not respond well if the amplifier can double its power as impedance is cut in half. It will result in no bass and too much highs. This is why tube amplifiers are often preferred for ESLs, despite the misguided attempts of several E... | |
Jadis JA30 - Quad ESL63 .. 4,8 or 16ohms? The ESL 63 needs more power than the S-30 can provide- at a minimum you need the M-60s. | |
OPamps still inferior to discrete circuits? So far in opamps the best I have seen for audio is made by Dan Kennedy:www.diyfactory.com/data/Great_River_Opamp2.pdf It is built up from discreet components. | |
Jadis JA30 - Quad ESL63 .. 4,8 or 16ohms? The Quad 63 has always been a great match with our M-60 and MA-1 amplifiers. The speaker has an impedance peak in the bass that is well over 40 ohms and many amplifiers, especially transistors, don't make a lot of power at that impedance. OTLs, OT... | |
"O Perfect Preamp, wherefore art thou?" I've yet to see a preamp that runs single-ended, but then can be balanced in the future... what we are really talking about here is a balanced preamp that can run single-ended for now.Most balanced preamps can do that.So- does this mean you want t... | |
Musicians? I started playing the piano when I was three. Never really took to it until much later- when analog synthesis came along.I was stunned when I heard native American flute for the first time. Later a friend gave me one and 6 months later I finally r... | |
VPI Scout- motor pops in speakers when turned off Usually a 0.01uf 600V cap placed across the power switch terminals is all that is needed to deal with this problem. That cap should not cost more than a dollar... we have them if anyone needs them. | |
Tone Arm Mass In the old days you could get non-magnetic weights for the tone arm so you could take care of this problem. You could mount them between the cartridge and the headshell or on top of the headshell. I've not seen anything like that in years, but it ... | |
The first-best-last analog item you ever bought My first real foray into reel to reel was an Ampex 350 transport with a pair of 351 electronics. I still have it. I've seen it eat a lot of newer tape machines for breakfast. I am certain it is by no means the best tape machine out there, but it w... | |
impedance vs sensitivity Blindjim, if I understand correctly, the Sonata IIIs have a substantial 4 ohm region in the bass, and 8 ohms (nominally) across the rest of the range. A tube amp is going to struggle with that 4 ohm region unless there is some provision made for t... |
