Brand New EL84, EL84M, 6BQ5, and 7189 tubes. 1980s NOS. Quad set. Below market price!

This is a brand new unused quad matched set of 7189 tubes.  They are burned in, tested and matched for outstanding tone and performance!  If you are running EL84s, these are a step UP!  I was blown away by the improvement when I switched out EL84s for these.  These are NOS tubes from the 1980s.  The 7189 tube circuit provides gobs of clean headroom, power, dynamics and harmonic content. PLUS, this 7189 tube is rated for higher power and plate voltage plus longer life making it a premium upgrade for amps with tough operating conditions. The solid construction and heavy glass also minimize microphonics. This tube is the perfect choice for Scott, Eico and Fisher amps. 

Ships to Contiguous USA only.  Ships via USPS priority mail for flat rate of $10.  

These tubes are only going up in price and due to the recent Russian export disruption it is happening fast!  Grab these while you can.  Great price!  Thanks for looking.
