Up for sale is my Wyetech Labs Opal Preamp. I have not had the time to use it in the past year, and decided it needs to go to someone who can. This has been the best preamp I have owned to date. Six moons has reviewed this wonderful piece, so I would advise anyone interested to go ahead and read their review. Comes with original boxes, and extra set of unused tubes. 3% charge paid by buyer for paypal transaction. Offers welcome, but please be reasonable.
