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,
akremer

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.
