JJ/Tesla 7027A Matched Pair
7027A JJ is a great choice on Ampegs and other amps that calls for 7027 type.
7027A JJ is built with sturdiness expected of the JJ power tubes, and at a fraction of the cost of NOS tubes. Price is for two matched tubes.
7027A is close to 6L6, but not pin to pin compatible. Use only where 7027A tube is called for.
