Channel imbalance

... Better that you got it sorted out. Enjoy..sup,
It's the front tube that will efffect channel balance the most (unless the large one is really, really bad), but why not get replacements for both? Some folks have also had some issues with the large, output tube, and why not play it safe, plus it gives you another flavor to try -- say try something like a 6as7 in place of the 6080 -- the presentation is bound to be slightly different and may sound better to you.
Just a suggestion.

Thank you for the replies and welcome Laudanum and Jim! It doesn't matter how loud I turn the volume the channel imbalance is always there.
The back tube seems to be in really poor condition - oxidized and very old. I will get both it they are not too expensive. Any recommendations as where is the best place to purchase them? Is ebay alright?
Thanks!

Welcome to BH. This Forem is what separates this company from anything else I have encountered. There is no way that I could be involved in DIY Audio without the help of these guys.

Thank you for the welcome and you reply Pat and at the same time apologies for late reply, I have been very busy for the past two weeks.
I have purchased 2x 12au7A/ecc82 RCA Tube CL Top *Test NOS* from ebay. I will first test the front tube and if that doesn't provide an answer I will order 1 power tube. Will report back. Thanks again everybody!

Hello guys, I just got the tubes and guess what - channels are now balanced! I am so proud of myself right now as this was my first DIY project and I was really thorough when building and refused to admit to myself I could have done something wrong. I am ecstatic right now as I got the tubes a day before I go on vacation till the end of the month and now I will be able to enjoy myself there even more. I am writing slightly under influence because after last night's live Buena Vista Social club concert I am still sobering up but could not wait to thank everybody who offered help here and the Bottlehead family. I just hope tubes are properly tested before shipped in the future as I was unable to listen to the amp for weeks because of the faulty tube. Thank you again!
Will be working on Speedball next month.

Great news! Although I've been doing this kind of thing for 40+ years, it's always great to hear when somebody with no experience at all can come in and build one of these kits and end up with a first-rate piece of gear. A lot of work and thought goes into making that possible, and that is what always never fails to impress me about what Bottlehead does.
Enjoy your vacation,
Jim
