TungSol 7591A Matched Quad


TungSol 7591A is a close replica of US made 7591A. It's true to the original form, and it goes perfectly in a Scott, Fisher or Gibson that uses 7591A.

We auditioned this tube extensively in our own Mcintosh MC225 and like it better than the original Sylvania 7591A.

Price is for a closely matched quad (4 tubes).
