Changing a rectifier tube question (Champ)...

[Bruce / Mission Amps]

To understand...it is not possible to get more than 8 watts out of a champ with a 6L6 and a 125ESE? I guess my understanding of the power output that a single 6L6 is capable of needs more study. I know that the output transformer is rated at 15 watts and the tube was biased pretty high.

On the subject...is it then necessary to change the output transformer when using a 6L6? Long term...

Anyway, my apologies to all for mis-speaking or causing confussion...but I guess that's what a forum is all about. Sharing knowledge.

It is a very loud Champ, though.

Thanks.

No, my bad I didn't realize the whole amp was modified to run a single 6L6.
A SE 6L6 amp with proper transformers and clean drive should be able to get somewhere around 12-15 watts output.
Fully cranked and allowing for massive 20%-30% distortion levels could easily get you 18 watts.
Sorry.

Modified Champ with 6L6

Thanks for that Bruce...(my name is David)

No worries...it does seem hard to believe...but as you pointed out massive mods were required to make the amp be what it is today. Keeping it stock was not part of the equation of course.

Anyway...I appreciate your insights.

Just goes to show that with a little elbow grease and a few bucks...a SF Champ is the best Class A amp value out there.

Kind regards and Happy Holidays!
