| Boutique caps in oil... reliable? I’m a little curious though, is oil-filled the same as oil impregnated? When I think of oil-filled, I think of big cans from the old days. AFAIK they are the same. Oil is used to reduce damage from arcing. | |
| How much does rear horn loading add to full range driver? What do you think about using good quality 'full range' driver as a midrange in 3-way speakers. What do you prefer for midrange in high sensitive speakers - 'full range' driver or compression driver with horn? @alexberger In case it wasn't obv... | |
| Advice on a tube tester I see tested and calibrated tube testers for $1500 on ebay but I think I can get by for a lot less. You probably can- and it will need servicing and calibration. You may well spend the same amount as a result. When testers like that were made ... | |
| Boutique caps in oil... reliable? We've sampled a number of oil filled caps over the years. I've not seen a type that didn't develop electrical leakage, although I'm sure they exist. Electrical leakage is where the cap takes on some of the properties of a resistor- a voltage can ... | |
| How much does rear horn loading add to full range driver? It's common ASR wisdom that "fullrange drivers are hot flaming garbage and you should be deeply embarassed to evoke them in any conversation". FWIW a friend of mine has been struggling with 'full range' drivers for the last 20 years. He keeps ... | |
| When someone tells you it's a $40,000 amp, does it sound better? Better: Smoother, more detailed, greater center image palpability. Wider bandwidth, particularly in the bass. Greater speed and so on. | |
| FUSE Question...Very Confused Please Help ! @rocky1313 The 250V thing is an arc-over rating and nothing else. For US operation you'll want the higher amperage rating as opposed to overseas operation. | |
| System that sounds so real it is easy to mistaken it is not live @rauliruegas It might be a good idea to have the suspensions of the drivers renewed. Its hard to imagine drivers that old that are working right unless they are either all paper or use a latex-impregnated cloth surround. | |
| System that sounds so real it is easy to mistaken it is not live There's probably a Nobel waiting for someone to show the inverse square law doesn't apply to sound from any source. @dogberry In a line source when you are close to the speaker the sound you are hearing is coming from right in front of you. As ... | |
| How much does rear horn loading add to full range driver? There are true full ranges just because one hasn't experienced one doesn't mean they all require being made into a 3-way. This statement is false, unless you can show me a driver that really in fact does 20-20Khz and not some made-up stuff like... | |
| What a difference a setting makes. @rvpiano Loading is really for the benefit of the phono section, not the cartridge. The industry standard for cartridge loading is 47,000 Ohms. But the inductance of the cartridge is in parallel with the capacitance of the tonearm interconnect ca... | |
| When to lube reel to reel tapes Have read that the lubricant on these tapes tends to deteriorate over time. Give the value of these tapes, would folks lube these before use, specially if they’ve not been played ever/very long time? Wherever you read that was misinformation. ... | |
| How much does rear horn loading add to full range driver? How much volume is gained by horn loading the rear wave? Would a horn enclosure 43 x 9 x 6" inches be likely to play lower than a ported shoebox size speaker? These wouldn't be my main speakers, just an interesting addition. @aldnorab Rear load... | |
| Help! Trying to pick an amp/preamp for an Acoustat 1+1s I'm going to move a tube amp into my second system room where I have some mature Martin Logan CLSs and see how it goes. I hadn't really tried it before. @carlsbad If you have CLS 1s you can do this easily. Any later version of the CLS is much ... | |
| Help! Trying to pick an amp/preamp for an Acoustat 1+1s @fortepiano50 , @charles1dad There are certain Acoustats that IME are very easy to drive. First let's debunk the sensitivity thing. While rated at 81 dB, keep in mind this is at 1 meter. This means that the efficiency of the speaker is actually h... |
