| Your journey with lower-watt tube amps -- Can a kit be good enough? @hilde45 That link doesn't seem to work. | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @hilde45 Excellent! If you change a component in your system and then you run into a buzz, this can be one of the causes. But in your case its not happening so no worries | |
| Calculation verification please @sksos1 The cartridge won't care about the 375 Ohm load. It won't care about 30 Ohms either. Loads like that are never for the cartridge's benefit; they are to eliminate RFI (Radio Frequency Interference) that LOMC cartridges tend to generate. Th... | |
| Spatial Audio Raven Preamp @lynn_olson +1 The tariffs will be doing no-one any good at all; just shortages, inflation and ill-will. | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? @hilde45 Nice to hear you hare having success! I prefer the JJ EL84s. You can get matched pairs at CE Distribution They have a Psvane tube that looks interesting too. If the power cord is grounded, sometimes you can run into a buzz problem (grou... | |
| More on XLR vs RCA considerations? I've never heard of a single ended triode preamp, but maybe that's just something else I've never known about until now? @immatthewj Most tube preamps are single-ended and triode. Its the rare one that isn't! Since my preamp and amp are sing... | |
| Cleaning amp/preamp If you have a board contaminated with oil a car wash (the kind where you use a pressure wash and do the cleaning yourself) can be a good move. I've had to do this a couple of times when customers put weird 'contact enhancers' on their tube sockets... | |
| Can you do anything to make power tubes last longer ? If you’re talking about the US, you are mistaken @atmasphere. Nominal voltage in the US is 120VAC ±5 percent, so anything between 114VAC and 126VAC is normal. That is established by ANSI C84.1 standard. @cleeds I stand corrected. However if t... | |
| Mullard EL34 that sounds best And as far as type I and type II, I see a set they are specifically calling EL34s type II and the rest are just EL34s, so are the ones that are called EL34s the type I? @inna as best I can make out the difference is how much plate Voltage they... | |
| Pick it Pro Balanced cartridge? real balanced? any good? So there is nothing unusual about the cartridge in the advertisement, good or bad. In balanced mode, the "hot" lead by convention carries the positive phase of the audio signal, and the "ground" lead carries the negative phase. Ground floats. ... | |
| Can you do anything to make power tubes last longer ? @inna For longest tube life: 1) keep the tubes clean and free of fingerprints. 2) keep them biased properly, if you can run them a little below spec. This works only if the sound isn't adversely affected. 3) use the Standby switch to warm up th... | |
| Somebody Please Make This Already... @eddnog We looked at something like this but the simple fact is to do bass management properly you start with a distributed bass array; four subs placed asymmetrically so to break up standing waves and thus have flat bass response everywhere in th... | |
| This Might Not Exist, Any reasonably priced, smaller speakers with 100db Sensitivity? If you don't mind DIY you could install a Tangband 1772 driver in a sealed box and supplement it with a tweeter (both crossed over properly to avoid comb filtering). Its 97dB and in a reasonably sized box (bigger bookshelf) would go to 45-50Hz. I... | |
| Mullard EL34 that sounds best @inna Mullard made a 10,000 hour EL34 FWIW. I've not seen one in 40 years or so. I doubt you're interested, but if you were to try new EL34s, if it were me I'd be using one of the JJ types (they make two) or something from Psvane. Considering ho... | |
| More on XLR vs RCA considerations? How on earth do we know if our gear supports AES48? @billpete You could ask the manufacturer. |
