Selected Vacuum Tubes

BWS Consulting supplies selected, medical grade, Telefunken 12AX7s and fully screened 6900 audio tubes.  I sell high quality vintage vacuum tubes from: Amperex, Bendix, General Electric, Mullard , Radio Corporation Of America, Siemens, Sylvania, Telefunken, and Tung-Sol.

I will consult with you about your audio system, so that we can select the vacuum tubes that match best with your equipment.  Please call me with model information and with information about what tubes you are currently using.

The following lists some of the tubes that are currently available for shipment:

All tube pairs are matched and tested in circuit.  Codes are matched when available.  Shipping is additional.

 


Bendix/Mu 6900 Selected Pair $1100.00   This pair (photos above) is  burned in and matched for line use or amplifier use.  These tubes have very closely balanced sections.  TV-2 readings are102/100 %quality, and 101/104% quality; where minimum is 63% quality.  It is common for  6900s to have grid leakage problems, so many of the tubes do not pass testing. I check each tube for current and noise in a balanced high voltage preamp circuit.  You are buying properly working tubes with a 90day warranty against failure.

 Bendix Redbank Flat Top  Selected Pair $1350.00 This very rare pair (photos above) is burned in and matched for line use or amplifier use. This is a very sweet and open sounding tube! These tubes have very closely balanced sections. TV-2 readings are95/95% quality, and 91/90 % quality; where minimum is 63% quality. It is common for 6900s to have grid leakage problems, so many of the tubes do not pass testing. I check each tube for current and noise in a balanced high voltage preamp circuit. You are buying properly working tubes with a 90day warranty against failure.
