NOTICE: Be sure to enter the Make & Model of component you are purchasing tubes for. Failure to do so will delay processing of your order. We do not ship tubes without this information.
Attention: Do not buy the Brimar CV4003 from ANYWHERE because there are counterfeit ones being sold elsewhere. If you bought them elsewhere and you plug them into a PrimaLuna, you may void your warranty. We have found better 12AU7's for PrimaLuna, go to the tube rolling page.
