2x ECC82 on Jadis JA 30 amplifier

The ECC83 should be next to the EL34, with the ECC82 in the back.... otherwise you will probably damage the tube and/or amp.

As I understand it the ECC83 has a higher gain than the ECC82. So it really shouldn't be a problem. It may sound a little more forward with the ECC83's though.

Best to contact Jadis - if anyone would know it should be them ;)

Thanks for the response. I ordered some ECC83.
I like the sound as it is now, hopefully it will be the same or better with the ECC83 in place.
I also contacted Jadis and yes I should put the ECC83 in. If it will harm the amp or tubes they did not tell me.
I will let you know.

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.
