| Skeletal vs Plinth style turntables Here is the issue in mechanical engineering terms. It is not a lot different from the steering and suspension of a car.In a nut shell:the plane of the platter must be consistent with the plane of the cartridge. As the arm moves the cartridge must ... | |
| Anything as " fast" as SPECTRAL gear? 'Fast' often refers to risetime or slew rate. Spectrals have always been very 'fast' in this regard. 100V/microsecond is generally considered 'fast'.Most tube amps are 'slow' by comparison- 15V/microsecond being typical. Our amps are 600V/microsec... | |
| Preamp: adjustable impedance + GAIN You just want the lowest output impedance you can get in the preamp.What is actually just as important is not so much that the output impedance is low, but also that it is the same at 20Hz as it is at 1KHz or 20KHz.If balanced, best results will b... | |
| Refurbish a Dynaco St70 ARC was a spin-off of Electronic Industries. EI is still in business today, but has switched over to making circuit boards. | |
| Importance of Amplifier versus Preamp? The amps have specs that are likely not a lot different from high end amps. The preamp however is a different matter- I would seriously look for a budget tube preamp for this setup- that would offer the most bang for the buck in terms of improveme... | |
| Empire 598 tone arm cable Radio Shack used to have the connector as they used to use the same setup on their car stereos many years ago. Don't know if they still have them. | |
| What is the best HEAVY METAL speaker? I bought the Mellotron used about 13 years ago and rebuilt it with a new motor controller, rebuilt the power supplies and replaced a lot of parts in the audio electronics.Right now I think I need to replace the audio input connector from the tape ... | |
| Refurbish a Dynaco St70 No- not done that. There's not a lot of room for another rectifier, and unlike some I really don't like modifying the chassis of older units- it usually damages their resale. For something like that I figure if a person has a better idea, best to ... | |
| Need advice on a tube line stage We just added a less expensive preamp to our lineup. The line section version retails for $1900.00... There is a review of it on EnjoytheMusic.com | |
| Speaker buzz with SS amplifier, input disconnected Would you kindly expound on the type of layout problem which might result in this speaker buzz. Can a noisy toroid transmit buzz to loudspeakers etcGenerally a noisy power transformer will not cause noise in the audio path as well. But there can b... | |
| What is the best HEAVY METAL speaker? Keyboards: Prophet 5, EML101 and Mellotron. | |
| Buliding off of my Technics 1200 I have a friend with the SL-1200 who did just this. He went with an old Dynaco PAS-3 and ST-70, both of which he had the power supplies refurbished. He really like the result. | |
| Speaker buzz with SS amplifier, input disconnected This sounds like an internal layout problem to me. It is true however that with an open input (nothing connected) that there will be a greater amount of noise present. But that should be gone with your preamp connected.Now one exception may be tha... | |
| What is the best HEAVY METAL speaker? Yes, I know they are a new band. But they sound a lot like Iron Maiden, except for the vocals. IOW, old school.I'll have to find an LP to really assess the recording quality. We (my band) were working on a mix of the last part of our 3rd album las... | |
| Refurbish a Dynaco St70 Yes, we have done that many times. A typical rebuild (such that the chassis is reliable) is about $200.00. This is mostly just repairing the power supplies and making sure that the unit meets spec with good tubes, but does not include any tubes th... |
