Thanks for checking out our massive tube collection! These tubes all originate from one of the largest collections in North America. 

All tubes have been pre-tested and matched (at no additional cost) on industry-standard testers. 

Quad of Sylvania 7027A power tubes. These tubes test good used. The 7027A's share a lot in common with the 6L6GC and were marketed by RCA for the Hi-Fi market as they are rated for greater power dissipation. The pinout of the 7027 also differs from the 6L6GC but internally they are very similar. These are great sounding vintage tubes that can be a great upgrade for your vintage amp or HiFi system designed to take the 7027. They are seen commonly in certain Ampeg amplifiers. We have some really great examples!
