| Weird problem. Bad tube or something else? An intermittent problem like this will not turn up on a tube tester. It does appear though that one or more of the Mullards are at fault and should be returned if warranty is still available. | |
| The End Of Big Iron? Mcbuddah, what is wrong with your Atma-Sphere amps? Bad tubes?A simple and inexpensive means of dealing with hot amplifiers, tube or solid state, is to install ceiling ventilation with ductwork to move the warmed air out of the building. This is v... | |
| What Determines The Amount Of "Current" In An Amp? There is confusion around this topic!Power (wattage) does not exist without voltage. If on the Voltage rule, loudspeakers are described as being 'Voltage Driven'. This is a sort of shorthand- it means that the amplifier is operating as a voltage s... | |
| Amplifier to power JBL Voice of Theater Speakers This kind of loudspeaker really will not sound right with transistors unless that transistor amp does not employ loop negative feedback (and most do).Such amps tend to cause a speaker like this to sound quite shrill (and is part of the reason horn... | |
| Why so few balanced phono inputs? Yes this is a BAL vs UNBAL conversation. Real quick ill just say BAL is for long cable runs, that's why you always see them used in professional stage gear. The balanced circuit is a more complex one and for home audio, depending on the engineer/d... | |
| Tube amp to drive Dali ms5 If the Dalis have as flat an impedance curve as suggested (as the Megalines do) that will help with the use of a tube amp.None of our customers have reported any feedback (we have excellent feedback on the Megalines) so I am only going by the numb... | |
| The End Of Big Iron? Basically, I have high efficiency speakers, so Class A should be no problem.Dave, those speakers are also an easy load for tube amps, which work quite well on them- several of our customers use similar JBLs (the export version). | |
| Planars/ Electrostats benefits over box speakers? The Mangaplaner 20.7 is one of the better bargains in the speaker world: fast, transparent, full range and not too hard to drive.The Sound Lab is the state of the art in ESLs, and much easier to drive than Martin Logans, and usually have greater s... | |
| Tube amp to drive Dali ms5 This speaker is not the best combination with tubes as it is low impedance (4 ohms) and low efficiency (86 db; their website claims a sensitivity of 89 db, but when you correct for the 4 ohm impedance and calculate for power rather than voltage th... | |
| EL34 & 6L6 characteristics We've gotten the best feedback from our customers on the Amperex Bugle Boy 7316. One of the best 12AU7 types out there. | |
| Getting the Upgrade Bug Again Yes, quite often B&Ws are not a good match with tubes, in particular the models with dual woofer arrays.But if you still have a hankering to show off the capabilities of a tube amplifier, try a set of Audiokinesis loudspeakers. They are reason... | |
| High value, high efficiency speakers for SET amps 4)I note that John Atkinson states in his measurements of the older de Capo i version of the speaker that "the speaker's low-frequency tuning is actually a little on the overdamped side." If the same holds true of Rebbi's BE version, its sonics co... | |
| EL34 & 6L6 characteristics You may find that the small (voltage amplifier and driver) tubes in the amp make a bigger difference than the power tubes, assuming that the power tubes are good when compared. | |
| "Warm Sounding" Solid State Amplifiers There are quite a few "great" sounding SS amps, now, and, as far back as the late 70's!One of those was the H/K Citation 16. If you found one though, expect to get the filter caps replaced. | |
| Thinking about buying a different tube preamp... If you can find a used Atma-Sphere MP-3 you should be able to pick one up for that price. Dual outputs are available and the phono section is entirely balanced-differential. |
