Matched pair of spare 6Ж51P (6Z51P) vacuum tubes

One (1) matched pair of 6Ж51P (6Z51P or 6J51P) vacuum tubes for the Shortest Way 51+ amplifier.

Order will include two (2) individual matched tubes. Exact appearance, factory stamps, production dates, and other minor details may vary between pairs or between tubes in an individual pair. Tubes will measure as or very close to NOS (new old stock).

March 2025: Due to the ongoing limited availability of vacuum tubes from Russia at this time, customers buying an amplifier or who have previously purchased an SW51+ amplifier from Zampotech North America or Zampotech directly in Russia will be given priority when inventory becomes limited. This is to ensure availability for as many customers as possible and to prevent reselling by third parties. Other orders may be cancelled and cancelled items will be refunded MINUS A $1.00 PROCESSING FEE.  This limitation will be removed once vacuum tubes from Russia are more readily available. Please contact us first with any questions regarding the purchase of tubes.

Additionally, any order that is deemed to be an excessive amount of vacuum tubes for the order or any customer ordering an excessive number of tubes in a given time period will have the extra or excessive tubes removed from their order.

This product contains nickel compounds within the vacuum tubes, which are known to the State of California to cause cancer. For more information, go to www.P65Warnings.ca.gov
