Thanks for all the information and the interesting debate, gentlemen.
To be clear, I will never change anything about the circuit of the HF25's - the same philosophy I followed during the rebuild of my Leak gear many years ago.
diyaudio and its members graciously provided all the answers to my question which was if there will be 'implications' wrt sound, operation or negative impact on other components of these amplifiers if ECC33 tubes were to be replaced by 6SN7 tubes.
With best regards and thanks to all who wrote here🙂

Is there a schematic with values etc available - I only have the plain schematic.
The feedback has both voltage and current take-offs, and the poor old ECC35 cathodes must be doing cartwheels with all the feedback contributions, including anode current feedback. I wonder if they really needed the two triodes in parallel?
