| Copper foil Nordost, Goertz, Mapleshade, Allen Wright/VSE are a few. McMaster-Carr sells raw electronics-grade copper and there are several small distributors of silver foil. | |
| Tung-Sol Reissue 6SN7 vs EH 6SN7 - Differences Jfrech, recabling of the intrachassic IC requires only basic soldering skills. I used a three-twist of Audio Consulting 24awg silver wire in natural cotton sleeves-- about $50 per chassis. You can use any good IC that isn't too thick to route down... | |
| Tung-Sol Reissue 6SN7 vs EH 6SN7 - Differences Woops, 6V6 not 6L6. | |
| Tung-Sol Reissue 6SN7 vs EH 6SN7 - Differences jfrech, not sure if it's me you're asking, but in the input section of the 75SE I'm using 6SN7EH, Tung Sol reissue 6L6, and 6H30pi/EB. The new Tung Sol 6L6 has great tone, and IME there is only a slight gain in this unit with NOS 6H30DR.I noticed ... | |
| Science & Sound, Tube or Solid State Phono? I recently converted the first gain stage of my Atma-Sphere MP-1 MkII to SS, thanks to Lewm and Allen Wright, who posts a schematic of his hybrid phono stage for DIYers. With a medium-output Helikon this was a significant improvement over the stoc... | |
| Tung-Sol Reissue 6SN7 vs EH 6SN7 - Differences It's good there are now two kinds of high-quality 6SN7s from New Sensor within a few dollars of each other. I have NOS Raytheon & Sylvania chrome tops to compare to EH 6SN7 & yes the NOS are better. But the EH are quite good. In many insta... | |
| Klyne 7 Phono with Bent NOH TVC The low 300R output impedance and high gain of the Klyne phono stage would appear to be a good match for a passive pre. You'll have a harder time finding a tube phono stage with low enough output Z to work well without additional buffering. | |
| 1970's For me the decade came in with The Who and went out with Talking Heads, with disco in between a very bad dream. | |
| Compare Shuguang vs ElectroHarmonics 6SN7 Glad finally to hear someone speak well of reissue Tung Sol 6SN7. Did you ever compare them to EH made in the same factory? IMO EH sound very good. | |
| RELcap PPMF vs Mundorf which one you prefer? Not exactly what you're asking, but Mundorf silver/gold were a great improvement over REL RT coupling caps in the phono section of my pre. | |
| Walker or VPI motor controller with scoutmaster? A new entrant is Mark Kelly's Synchrotron AC-1. Available in kit form only, the AC-1 derives 120VAC from a large 12V SLA battery. Build cost ca $500-$700 including battery. It has the theoretical advantage over single-phase controllers like SDS an... | |
| Rich; organic true balanced amp w good detail $6k I went from an ARC VT130 to a BAT VK75SE. I later modded the BAT with V-Caps and a few other minor changes that significantly improved resolution, neutrality, dynamics, bass extension & control-- IMO putting the amp at par with a top OTL. Ther... | |
| Copper foil Rather than explore relevant Bessel functions & Maxwell equations in a non-technical forum, I suggest that doubters spend $100 at McMaster-Carr for some electronics-grade copper of equivalent gauges in both formats & experiment. You will b... | |
| Copper foil Palerider, Far from "hi-fi legend," skin effect at AC is well documented as variation in impedance against frequency that occurs at difference depths of a conductor. The effect becomes pronounced at frequencies above a few kHz. It's not true that ... | |
| Implications of Esoteric G-0Rb atomic clock Ehider, I agree that too few direct comparisons are made between RBCD and the benchmark of great vinyl when judging the performance of a CDP. However, I make this comparison every day, and have come to the conclusion that it is indeed possible for... |
