OT: Samsung to turn cluelessness into money

They don't mention dipping that stuff in LN2 _at all_ -- so it must be plain old ordinary crap whose crystalline structure isn't aligned in an acoustically balanced fashion.

Where does "Dual Rectifier" fit in? It reminds me of the time someone brought me an amp he garbage picked that had some broken tubes: Could I repair it? I had a pair of KT-66 output tubes, but I didn't have 5V4 rectifier, so I soldered a pair of 1-amp silicon diodes from the junk box to the right pins of the broken tube's octal socket, and the thing worked fine. The dumb cluck was sure that the diodes ruined "that tube sound", so I swapped it with the rectifier in my old Williamson in the attic. He swore it made a difference. > http://www.freeinfosociety.com/electronics/schemview.php?id=506 What does V1b do? I see the dual rectifier. Silicon!

Not that I completely understand the "tube sound" but a soft power supply might make some difference. A resistor in series with the diode might also work. >> http://www.freeinfosociety.com/electronics/schemview.php?id=506 Oops. Ignore the above comment. > What does V1b do? I see the dual rectifier. Silicon! Horrors! Following my comment on a previous post, someone should build a device with a DAC, vacuum tube, ADC, so one could add "tube sound" to a digitized signal. I don't know that the DAC and ADC need to be tubes, as long as there is one in the signal path. -- glen
