| Can You Live With Crackling & Popping Noise? Excess surface noise can be the result of a MM cartridge loaded with too much capacitance. This capacitance interacts with the cart. inductance resulting in a high frequency resonance (see Jim Hagerman's web site). Ultra-sonic noise can excite thi... | |
| Silver solder--what wattage soldering iron? I use Cardas Quad Eutectic in all my work. It flows and works beautifully and produces great looking solder joints. The newer Cardas solder without lead doesn't seem to work as well. I would try to get the older "Quad" formulation. | |
| Tonearm Upgrade for Spacedeck I'm running a Hyperspace and have been very happy with an OL Illustrious with a Riggle VTAF VTA adjuster. Never had the Nott. arm so can't speak to any differences. | |
| Tube Tuners Modified Fisher 100b (IEC 3-wire power input, HEXFREDs in PS, film bypassed Jensen PIO coupling caps). | |
| Anyone modify the K&K phono stage? Yes and yes. If fact, the circuit topology of the new phono pre is very similar to your Vivo amp. I built mono-block parallel 6550 versions of your Vivo amp and they are awesome. So if you are happy with the Vivo you will also be very happy with t... | |
| Anyone modify the K&K phono stage? This isn't really a "mod" but I am (finally) burning in Kevin's newest creation. I have one of the beta versions of his Sonas Veritas phono stage and it is a dreadnaut, over 37 pounds! Three stage fully differential series feed, transformer couple... | |
| Top line phono stages with at least 2 inputs Kevin Carter of K&K Audio has a new high end design that will sell under the Sonus Veritas name. Look for it in the near future. | |
| I could cry One of my cats recently "modified" the dome tweeter on one of my speakers. It's now an "inverted" tweeter! Fortunately the hit to the wallet wasn't too bad. So the cat's off the hook. Besides I'm a vegetarian so barbeque was never an option. | |
| K&K any comments? Yes I do have the current phono pre. It was the first complete kit Kevin sold way back when. It has all current upgrades. | |
| K&K any comments? Just to stir the waters a little: Kevin has a new phono stage design that is ready for roll out in beta form. Fully differential, 3 stage, series feed (current kit is parallel feed) design with cascode CCSs at the "tail" of each stage and a separa... | |
| Turntable Speed All DC motors for TTs will have by necessity some form of feedback to control their speed. If a TT has a DC motor it will come with a dedicated speed controller. AC motors "synchronise" with the frequency as has been dicussed. That is not the only... | |
| Phono Preamp Suggestions? 38ohms. That is the impedance reflected by the Lundahl MC trannie wired 10:1. I have a 3.8K resistor in parallel with the secondary. Divide that by 10 squared you get 38 ohms. In my set-up the highs were a little too pronounced with less load (42 ... | |
| Opinions on Glass Shelves I have a Sound Organization rack with glass shelves. I replaced the top shelf with a custom made Neuance shelf for my TT. The other shelves have 12"x12" sheets of asphalt damping material applied to their bottoms. Not a high end rack by any means,... | |
| Phono Preamp Suggestions? You should consider upgrading the 90X to the new 9000. I used a 90X for 3 years and was surprised by the difference that I heard when I switched to the 9000. Made me think the 90X was defective. Cleaner, quieter, more involving. Well worth the cos... | |
| Triple deionized water for cleaning lps ? You can take the "purest" water on the planet and if you store it in glass it will leach minerals from the glass. If you store it in plastic, it will leach plastisizers from the plastic. In both cases it will absorb carbon dioxide from the air, lo... |
