Brent Jessee

Despite some folks not liking Upscale and Kevin Deal I've had good service, great tubes, and no problems from them.

Andy from Vintage Tube Services accepts returns and will work with you to find the right tubes.

Brent Jessee will also exchange tubes.

I agree that Kevin is a DICK !
My dealing with him were not good
He does not want to honor his warranty.
Andy at Vintage Tube Services , is the best
He prefers a phone call.vs email
Below if from his website

Additionally, my experience is that I get to the bottom of specifically assisting your needs more efficiently and effectively having a personal discussion. My ultimate priorities are the phone calls from my clients and fulfilling their orders. Please feel free to call me. I’d be happy to share my knowledge, experience, and expertise with you.
