Thanks to the OP for getting this started. I know it’s been argued about over and over and round and round. But I’ve enjoyed reading the posts, including the links. This all will be settled by approximately never. Yet it remains interesting to read about. To me.
Signal tube versus power tube, sound impact?
My mono block has eight KT 88 tubes(power tubes) and six smaller signal tubes. I'm using the stock tubes that came with each Mono. I think they are JJ tubes.
Rather than replace them all would it be best to change out the signal or the power tubes? Not sure how good the JJ tubes are but I hear they may not be the greatest.
