My Octave V70se has ECC81 (12at7) as standard driver tubes. The manual states I can use either ECC81's or ECC82's. The ECC82 (12au7) has less gain than the ECC81's. So for grins I popped in a pair of ECC82's and I have more volume to play with. The overall top loudness stays the same but I can go higher on the volume knob with the ECC82's (not louder though) without adding noise and in fact sounds a bit better. When funds permit I'll try some different ECC81's.
2x ECC82 on Jadis JA 30 amplifier
Hi,
I just got 2 Jadis JA 30 amplifiers and I love the sound. But they both have 2x ECC82 next to the 2x EL34 end tubes. According to the specs it should be 1x ECC82 and 1x ECC83. Will the change of ECC83 into ECC82 harm the amplifier or just the sound of it?
For pre I use the Jadis DPL2.
kind regards,
