These have been installed briefly in a DAC project that I subsequently abandoned so only used for about an hour. Now surplus to requirements and funds needed for a new pair of bike wheels.
A pair of these, without the switch will cost you around £325 ($395) plus shipping. Add another £50 ($60) for the switch and you have the best part of £400 ($485) . I'm looking for £225 ($275) plus shipping and PayPal fee. PM if you're interested.
Please note: Included are the two TVCs with their mounting brackets and the Seiden switch. None of the hardware pictured is included. What looks like scratches on one of the TVCs is just a reflection.
Cheers
