7027A USA USED/ TESTED Matched Pair
We are now offering matched pairs of vintage used USA 7027A.
Great for those who want Vintage tubes at a reduced price. Great as main pair or backup.
Tubes are both trans-conductance matched on a B+k 747 tube tester and current draw matched on a 1971 Ampeg V2 amplifier.
Please note tube pairs are electrically matched but may not be matched by the brand name screened on them. Where possible they are selected by tube architecture (manufacturer). Back in the day a tube may be branded Sylvania but actually be made by RCA etc.. We still effort to match for branding when possible.
30 day warranty on NOS tubes.
NOTE: For safe operation you must check your amps bias and reset accordingly with any power tube change.
Failure to do so may result in both amp and tube damage.
