Used to repair a Bronco with a failed OT.
Installed, used the higher primary tap and also used a NOS GE 6V6. Worked just fine after changing the value of the cathode resistor to get the desired bias/idle current. Sounds good, good value.
I put this in my 196 tweed fender champ And put the original speaker in storage. This speaker sounds awessome and it fits perfectly. Turned up loud it just sings And it can easily handle the power.
