| Phonostage, preamp or amp? Of all tubes power tubes are probably the least reliable.My suggestion is start with a tube phono section if it is to be a stand-alone from the line stage (which IMO is a bad idea but that is a topic for another thread). This might sound a bit odd... | |
| Amp repair cost — is this right? Due to some experience (the hard way) I noticed very high price differences from technician to technician. So $105 - $12,- an hour. A tech working out of his basement is going to be less expensive but he'll be more than $12.00/hour (unless he's d... | |
| Are there any tube amps that don't give off any--- Tubes have to heat their filament to be operational. That is their principle of operation. It is, but that is not why tube amps run hot. I explained that earlier.My dedicated room is a stand alone structure on a concrete slab. No basement. 'Stand ... | |
| Are there any tube amps that don't give off any--- punch a small hole in the wall and put the amps in the next room.@daveyf This isn't a bad suggestion. We have a number of customers that have their amps installed in the basement beneath their listening room, near the ceiling so the speaker cable... | |
| Amp repair cost — is this right? @jnehma1 Did you see my second post on this thread? Because the filter caps are snap caps (which are a lot less expensive) I revised my thinking about a fair price downwards. I was figuring at least $800 for parts but the snap caps will only be a... | |
| vinyl versus digital redux @mijostyn Its funny how much better a master digital file is than one that's been exposed to DSP! | |
| Amp repair cost — is this right? Are you all referring to the ’same’ capacitors? Such a vast cost spectrum being cited. Ralph you build and repair audio electronics and would know. Just curious as to the wide variance of price. Apparently not! Snap caps are a *lot* less expensi... | |
| Amp repair cost — is this right? Audiogon is a very strange place. I’m simply asking if this price is in the right range and getting some really strange responses that don’t answer that question.I don’t see that as unreasonable. If one cap has already failed and it has 18 caps in... | |
| Are there any tube amps that don't give off any--- No.But trust me on this one- I've seen it- a fan is a **LOT** quieter than an air conditioner! You can hardly tell its on, yet the installation I saw kept the room cool despite a pair of class A triode OTLs with 42 power tubes per channel making o... | |
| vinyl versus digital redux Hm. One thing I don't see mentioned here is the issue of bandwidth. Any LP made since the dawn of the stereo era (1958) has potential bandwidth to over 40KHz. Bandwidth during playback has been in that realm for a while too- most phono preamps hav... | |
| Never Owned a Tube Amp and Want Advice In the meantime, I set up my turntable.This is a Technics SL1200Mk 5 with an AT150MLX cartridge. Turntables, especially those with high output, can have a variety of issues causing sibilance. Make sure you have a low capacitance cable between the ... | |
| Are there any tube amps that don't give off any--- Why not just vent the heat out of the room? A ceiling vent isn't expensive to install and some dryer duct hose will send it out of the house with the help of an inexpensive low speed fan. Then air conditioning won't have any trouble keeping up; yo... | |
| Low power, class-A solid state and high impedance speakers Assuming that the loudspeakers are sensitive enough not to suffer from the amp's lower power output, are there any downsides to doing this? Any other upsides besides lower distortion?No downsides, and an additional upside is it will probably run... | |
| Passive preamp issues or? @renisnceman You might try lifting the ground of the DAC to see if you are dealing with a ground loop. You do this by getting a ground cheater adapter for your its cord at the local hardware store and plugging the DAC into the wall using the ada... | |
| Passive preamp issues or? If the amp really has a 1MegOhm input impedance, that is likely the problem- it will make it very sensitive to cables (and much more able to pick up hum from high impedance sources!). The input impedance isn't specified anywhere I've looked so thi... |
