sasqwatch Posted July 4, 2014 Share Posted July 4, 2014 What i am wondering is, if the signal that is being amplified is a wave and the top of it is pushed by one tube. Then the bottom half is pulled by the second tube. Are certain frequencies in the top half (ie. higher frequencies).Then the bottom half the lower frequencies. My thinking then ,if that be the case . Could one use maybe a telefunkin for the push and somthing like a mullard for the pull tube. Please feel free to educate me if I am seeing this wrong or if you hage tried this and what kind of results you experienced. Quote Link to comment Share on other sites More sharing options...

Arash Posted July 4, 2014 Share Posted July 4, 2014 push pull means upper section of signal swing is up to one tube and the lower is another tube duty but this is different from high or low frequencies! in other word, in a PP tube amp, all the frequency bandwidth is covered by two (lets keep it simple) tubes which are phase inverted. the overall output is what makes frequencies.

sasqwatch Posted July 4, 2014 Author Share Posted July 4, 2014 Thanks Arash for taking time to reply. But I still wonder if there would be any benefit to using two different tubes, maybe get a blend of the best characteristic of each tube. Sorry for typo in original post, posting from phone.

Sorry for typo in original post, posting from phone. can a push pull tube amplifier use nonidentical tubes at output stage? I'm gonna answer this question with another question, I would say a rhetorical question can a car engine work properly with unbalanced pistons?! output transformer of a push pull tube amp has a two-sectioned primary.

Don Richard Posted July 4, 2014 Share Posted July 4, 2014 A PP amplifier's tubes (or transistors) must be balanced or distortion will result. Quote Link to comment Share on other sites More sharing options...
