audiowize if you look for perfect DC square wave (!!!)
give up tubes amplifiers
discrete circuits perform much better at very low cost
tube amplifiers are from the beginning of hystory
direct heathed triodes and transformers
every ting else no matter of interest for my
and i hate capacitors and transistors, from four decades
every day i replace death capacitors and transistors
and resistors of course

A capacitor is still in the signal path with an interstage transformer, it's in the power supply...
Because of this incredibly common misconception that an interstage transformer magically removes capacitors from the signal path.
We agree that, in an SE amplifier, the power supply capacitor is in the signal path.
The subject here however is about pros and cons of IT, direct and/or RC coupling.
So please stay on topic 🙄

The OP asked if his amp could be transformed by IT coupling or direct coupling.
Another member said that you could remove "the death capacitors" with an interstage transformer. I corrected this. This is very much on topic.

Can you quote that the other member replaced "death capacitors" with an IT?
Sorry, you seem to loose your arguments....🙁
So your post #26 is false. You pulled Claudiomas' remark on death capacitors out of it's context; be aware that English is not his native language, and that it is no so difficult to tackle him on his words.
Audiowize I am done with you: I stop discussing with people who repeatedly use false arguments, and bring up other issues when they loose their arguments.
Good luck!

Perhaps you don't have a lot of experience with transformer evangelists. This was really, really common back in the 90s, when amateur builders would replace a coupling cap with an interstage transformer in a single ended amp and then proclaim that they had "no capacitors in the signal path".
Claudio's statements that he loves transformers and hates capacitors is very reminiscent of this sentiment of working toward no caps in the signal path. You can approach this by using regulated high voltage power supplies, but this requires solid state components, and he has lumped these into the bad category with capacitors.

no i build 3 smps amplifiers, 45/2A3/PP211 transformer coupled its powered by 3 smps 300V500mA for 1200V and PP GM70 transformer coupled also and SE 813 /6BX7 choke plate /6C45PE plate load drive by oil capacitor, some time i use capacitors you see these amplifiers are in this forum.
I'd like to build the CCOS 45 by g. rankin posted above. I have all the iron already on hand except my OPT 's are magnequest parafeed's exo-46's w/ matching chokes also by mike l. Would the circuit be compromised if I were to revise it for parafeed output?
