Whatjd,

I would highly recommend Andy Bouwman at Vintage Tube Services. You can check out his website at www.vintagetubeservices.com. He is located in Rockford, Michigan.

Andy has as knowledgeable about tubes as anyone you could find. He basically has been a student of the vacuum tube since he was a teenager.

I have purchased a number of NOS tubes from him. The results of adding these to my system has been nothing short of miraculous.

Good Luck!!

I've had great results buying tubes from Jon at The Tube Store. He knows his tubes and the service is excellent.

I take my chances with eBay. I find it's cheaper.
