Decware issue

[Toronto]

Hi just complete my Decware DIY SE84 amp and one side there is a issue.It plays ok for a second then slowly the volume falls to almost zero.I check the tubes,swapped tubes,cable,check the caps.Everything seems ok.The single driver tube by my tube tester indicates its weak.Could a single driver tube cause the inbalance of the channels volume?.

Does Decware provide a list of voltages to check?

Yes voltage seems fine...So one channel is low volume and some static.

A dead tube or half a tube will cause voltage issues. Specifically the voltages at pins 1 and 6 should start to creep up.

Otherwise I would suggest that you have a problematic solder joint.
