Tim de Paravicini don't recommend us to use 6DJ8/6922 in PCC88/7DJ8 positions or vice versa. For details, please see another post "Interview with Tim de Paravicini at High End Audio Show"
I had tried to put E88CC in my EAR 88PB after the interview. The higher voltage lighted up the tubes with abnormal brightness and sounded strange. I had also tried to put PCC88 in 6922 positions and the sound was just twisted. I wouldn't dare to keep it that way for too long.
