| Thiel Owners Holco - nice work and thank you. Please remind me of your serial numbers for my reconstruction records. FYI: part of the reason for the "eager appreciation" is that the other parameters are all designed for maximum performance. The driver motor di... | |
| Thiel Owners Rules - I have a schematic derived from real unit by a DIY. If that would help, I can email a copy to you. Tom | |
| Thiel Owners Holco - the woofer is 4 ohm, then incorporate any zobel network values for actual woofer impedance. Perhaps talk to Jantzen about unwinding. | |
| Thiel Owners holco - unwinding is very common practice. I've never done a foil wax, but it sounds easier than a bonded coil.I'm not following your math. 30 Hz seems like a big change. The complex effective resistance will be different with foil vs round. Can y... | |
| Thiel Owners Through all of Jim's final listening / troubleshooting / optimizing phases, the parts were mounted on the actual crossover boards with all input and output leads attached to real drivers in their real cabinets. Therefore any leakage, environmental... | |
| Thiel Owners Andy - thanks for the clarification. The C is for Copper in CSA and the CSA is reported to be a big step better than the SA. One day I will directly compare the SAs from the 2.4SE with the new CSAs. | |
| Thiel Owners "I have used the Clarity CSA (the older version, not the latest one with their newer Copper Technology), Mundorf Supreme cap, and Jantzen Z-Silver."Andy - would you please clarify which ClarityCap you are referencing? The CSA has the copper ends... | |
| Thiel Owners JA - how do we access desmond's project. Or, can you get him to report here? | |
| Thiel Owners JA - I suspect you haven't gotten satisfaction re your impedance / phase query. Technical study and understanding underlies amp loads. Here's a superficial sketch: Impedance (AC resistance) can be mechanical, electrical, inertial, etc. Voltage is ... | |
| Thiel Owners sgmlaw - your Hafler story represents the approach of a wide range of designers, and practically the entire DIY community. I will offer a different perspective which included Nelson Pass, John Dunlavy, Benchmark's John Siau and Jim Thiel to name a... | |
| Thiel Owners Beetle - thanks also from me for your steady, careful implementation, especially when backing out of blind allies.You all may be interested to know that the 03, 03a/b, CS3, CS3.5 and CS2 had styrene micro bypass caps (0.01 and 0.015uF), similar to... | |
| Thiel Owners Andy - my first-choice idea for multiple runs is to twist the bunch (2 or 3) 18 ga varnished coil wires having essentially no dialectric. That wire-twine is insulated with a cotton sleeve (very low dielectric absorption) if physically necessary - ... | |
| Thiel Owners I share the surprise of learning of Chinese sourced components. I am gradually making sense of the history and can speak more readily after the Thiel bankruptcy closes. I will say that Jim's decisions were careful and considered. I know that FST, ... | |
| Thiel Owners To clarify, in the last paragraph of my previous post I was referring to "wire", not the brand StraightWire. I meant to say that all wire has many effects and artifacts beyond resistance, capacitance and inductance. Most of those spurious artifact... | |
| Thiel Owners Sgmlaw - We were aware of the Bell Labs research, which concurred with Jon Dahlquist's exclusive use of 18 solid in the DQ10. We compared 18 solid with 18 stranded and the solid won hands-down. Cousin Ted concurred and we went with 18. In my prese... |
