Hello,
I bought some tubes to use with my Musical Paradise MP-301 MK3. There were problems with the MP-301 MK3, so it has been returned. Now I have tubes for an amp that I no longer own.
All of the tubes were bought from Tubeworld as NOS matched pairs. All contacts were cleaned and treated with Deoxit. The contacts on the 713A's weren't pristine, so they were cleaned with an abrasive prior to the Deoxit.
I did use the 6SJ7's--probably put about 200 hours on them. The 713A's were briefly tested for functionality once and put back in the box afterwards. They were sold with ratings of 8.8MA and 9.0MA.
