“An awesome tube, the sound in my PrimaLuna was amazing but with this Brimar went to the next level. Shipping on time and excellent customer service as always.”

“Sounds fantastic in my Vincent Pho-701. The sound is more musical than the stock tube, not bright, just perfect (for picky guy like me). Very happy!”

“All I can say is WOW! The soundstage opened up big time after replacing the stock tubes in my PrimaLuna Amps and Preamps. A pleasure doing business with Kevin and company, and a special shoutout to John for his help.”

“Incredible sounding tube. I will need three more. They completely changed the tone profile I was used to and it has been nothing but positive. Thank you for creating the chance to get tone I have been looking for”
