| Sansui AU-111 vacuum tube amplifier I used to service those amps back in the day... At the shops where I worked I tended to be the one doing the tube equipment when it showed up. The output transformers were pretty decent. But the parts quality was pretty bad. They used paper and oi... | |
| Again the topic of weight of amps On account of the fact that our amps don't have output transformers, they tend to be lighter than other tube amps that make the same power. For example our 140 watt amp weighs 36 pounds. It’s no secret that big honking transformers produce toxic m... | |
| Why According to some Turntable extremists Pitch Control and Direct Drive is Sacrilege? So called, home market equipment made today in garage is designed by mediocre engineers, who don’t have enough education and talent to work in Hi-Tech. Except for those that have degrees?? Obviously this statement is false. ALL vinyl record lacq... | |
| oscillation in power supply filter caps Hello, I replaced the four filter capacitors and now I have a minor amount of resonance in all the caps now. what gives or is this normalWhat is meant by 'minor amount of resonance in all the caps now'?What are you hearing through the speakers? | |
| SET amplifier recommendation @jdl57 6 watts isn't going to do it on the 805. Quite simply you need some power. | |
| Balanced vs RCA between amp/preamp the sound of the interconnect won't be a thingMalarkey!Assuming balanced circuitry and connections are properly implemented, which far too often they are not, they can reduce common mode noise. FULL STOP.For balanced interconnects to be immune to... | |
| Balanced vs RCA between amp/preamp that being said your Amplifier and preamp need to have transformers for the input,outputs to be what is considered a True balanced . This statement is false. You don’t need transformers, but without them supporting the balanced standard gets a lot... | |
| Balanced vs RCA between amp/preamp Balanced are designed for professional use. That is why they are designed with the ground making contact first- professional use sees a lot of stuff being connected/disconnected while powered up. Making the ground connection first avoids the lo... | |
| How do I smooth out violins? I switched to a tube preamp using some great NOS tubes that rolled off the highs a bit, but still sound very open (RCA Blackplates). Strings were finally sounding very natural, and it was now easier to tell which cds were poor recordings.Get b... | |
| SET amplifier recommendation That’s an interesting point, Ralph, which I presume derives mainly from the bandwidth limitations imposed by output transformers when they are used in SET configurations.Would the bandwidth limitations you refer to apply to the small signal ban... | |
| SET amplifier recommendation How different is the sound between 300b and 805 (LM 508AI, etc)? With SETs, the bigger the amp the less bandwidth. 300b is about as powerful as an SET can get and still be considered 'hifi' as far as bandwidth goes. | |
| SET amplifier recommendation The B&W speakers are voiced for SS amplification and are never going to sound their best with tube amplification; possibly with the exception of a pair of Atma-Sphere OTL monoblocks. We’ve got several customers that are very happy with this co... | |
| SET amplifier recommendation The speaker is a problem for almost any SET. But you've not exhausted all your options. You could also go OTL. Its possible to have many of the advantages of SETs (magical inner detail, amazing midrange) without some of the disadvantages (low powe... | |
| Cartridges that get strings right? I’m intrigued about the comments about tracking. Getting the fundamental and the overtones right (for those who like statistics: I suspect “right” has a lot to do with an even transfer in the frequency domain and minimal phase distortions in th... | |
| Jupiter Copper Foil, Paper & Wax Cap Versus Jensen Cap 0.10uF 630Vdc Copper Foil Ceramic Has anyone tried Jupiter Copper Foils bypassed with a V-cap CuTF? Just curious if a .01uF V-cap would benefit a Jupiter CF with its resolving and leading edge detail or will it detract from the Jupiter's already beautiful organics?It really do... |
