| Tube Amp for Martin Logan Speakers Hvowell, said earlier:Now is the reason this type of amp works is (assuming the speaker has a sensitivity (SPL) of 85db/1W into 8 ohms).25W into 32ohms = 85db.50W into 16ohms = 85db1W inot 8 ohms = 85db2W into 4 ohms = 85db4W into 2 ohms = 85dbso ... | |
| how much current does a yba 600 power amp provide. The amp can make 300 watts into 4 ohms.The power formula is Power = Resistance x current(squared).So if 300 watts, divide by 4 (if that is the impedance of the speaker) and the result is 8.66Amps.You may see much higher current ratings advertised ... | |
| Custom Bridge Rectifier on a preamp power supply Actually I mentioned why that is in my first post on this thread. | |
| Custom Bridge Rectifier on a preamp power supply ^^ I was trying to keep my response simple!I saw a really simple solution that involved the use of a tube rectifier, which due to its linearity does not induce swept inductance issues. It was bypassed with a set of ordinary diodes. So when the dio... | |
| Heat heat and more heat?? In the home environment, where I am running cables that are what...1.5meters typically ( and VERY well shielded) I just don't get it. The extra expense and hassle for balanced..why??The reason for this is that balanced connections (if done correct... | |
| What is the best tube pre-amp for my system If you don't plan to use any other source, while I rarely agree with George (and his comments about tube coloration are really off the mark), in this case it does not seem to make a lot of sense to employ a preamp.Now if you have to have long inte... | |
| Custom Bridge Rectifier on a preamp power supply The big issue is that rectifiers make noise due to a phenomena called 'swept resonance'. This is caused by how the rectifiers turn off in conjunction with the power transformer inductance. To prevent this problem the rectifier has to be neutralize... | |
| Power Amp Repair Question I used to run a service shop and we still repair stuff now even though we are really a manufacturer. The shop in question is on thin ice with this one- no service rendered, and they want to keep the money?? No excuse really. | |
| Is it time for a phono stage? We make a full function preamp, the UV-1, that falls in this price range... | |
| "Audio Gone" question for Audiogon experts OK. Next is to find out if the one channel is fading, or if the other is getting louder.I've seen feedback resistors fail before, so getting louder is something that should be checked out. | |
| Love / Hate relationship with vinyl? Another thing to consider is that SUTs are not as cartridge-specific as you may have thought. The loading of the transformer with a given cartridge at the input *is* however.If you get a Jensen SUT (which are some of the best made, price no object... | |
| "Audio Gone" question for Audiogon experts Does this occur on all functions? | |
| Phono cartridge for classic rock There is no such thing as a cartridge or arm that is better at rock than anything else. That is a myth plain and simple. Electronics (including speakers) don't have taste and can't tell what music you are playing through it.In short if its really ... | |
| In Memoriam: Bobby Palkovich of Merlin Music Really sorry to hear this! Bobby has always treated me and our customers with 110%. Its hard to imagine he's gone... | |
| Passive & Tubed pre-amps to power amp at same time? More so on the output side than the input, but they are sensitive to the input side as well. As a general rule of thumb keep the cables short! |
