Mullard CV4003 12U7 NOS, Cryo'd, CJ Tested Pair from Upscale Audio.
I sold all my tube gear and these are left. They are virtually unused and in tip-top condition.
$175 for the pair - Includes USPS Priority Shipping (CONUS) and Paypal fees.
I have a 100% rating on Audiogon.
Let me know if you have any questions and thanks for looking!
