FOR SALE: 6528 Tubes (Used/Tested Quad)

Diogenio · 26th April 2009, 12:59 AM

Set of 4 tubes. My EBAY item number: 270380504435

These tubes have a mu of 9, a low plate resistance and lots of current handling capacity. They are a sleeper of a great single-ended amplifier output tube! A number of different SE amplifier designs have been published, including an interesting "cathode-follower" design in Vacuum Tube Valley - and I will provide a copy of this article if the buyer requests.

Other articles with 6528 amplifier designs are found in the "Glass Audio Projects" book, and in Morgan Jones' book, "Valve Amplifiers."

Take a look!

ebay bidders traditionally don't start bidding until the auction is close to being over.
