of the three brands i ordered, this and the GE were microphonic and unusable as reverb driver/receiver in my Swart Space Tone Stereo guitar amp.
This is the perfect phase inverter to for the Fryette Power Station 100
Excellent Reverb driver tube,quells overly wet reverb as it’s a dual triode and one half operates as a ax7 and the other half as a au7(roughly) 20% of ax7 value..
Gets you a nice sweep,highly suggested..
