Brief Introduction to 6DE7/6EW7 :


6DE7/6EW7 is a dual triode tube, consisting of one drive triode and one power triode. Its performance is similar to a combination of a 6SN7 and a 2A3.


Tubes Upgrade (buy separately, please call for pricing) :


- Rectifier tubes upgrade 1, Takatsuki TA-274B (1 pc) with 1-year warranty


Takatsuki 274B offer ultimate performance to any current production 274B's. Users have claimed that it exceeds the quality to NOS Western Electric 274B.


- Rectifier tube upgrade 2, Sophia Princess Mesh Plate 274B (1 pc) with 30-day warranty


To impact WA6-SE's sound quality or for your super backup.

Sophia Electric™ 274B tube is a premium rectifier tube for a 5U4/5R4/5AR4 direct replacement with 3X longer plate structure, thus it has a deeper, wider sound stage and even smoothier sound than Mullard 5AR4.


- Drive/Power tube option 1, one matched pair of 6GL7/6EM7 plus 1 pair of 6GL7->6DE7 Teflon tube adapters (2 tubes + 2 adapters)


The 6GL7/6EM7 is the ultimate driver/power tube for the WA6. It has great extension and excellent clarity on all frequency range. You will hear each note with breathing air around it. The sound is smooth and well balanced.


This tube is compatible to the WA6. You will need to use a tube adapter becaue the pin layout is different than the 6DE7/6EW7. It is a twin triode tube with high amplification factor. It produces higher output.

Clear top, big bottle. 6FD7 is a direct replacement for a 6DE7.


- Drive/Power tube option 3, one matched pair 6EW7 (2 pcs)
