Many thanks!
Have a great evening!

Would anyone happen to have the general fix for the hum that can appear with the Audiotailor Jade that develops? I would believe that it is related to the grounding. The hum seems to be not altered by volume and is present of both channels.
Thanks for the response. I guess that it must be either a capacitor that has gone faulty or a ground solder joint has gone (valves were the first to be tested). I am certainly leaning towards the solder joints as the ones around the main socket aren't looking good at a glance. Locating the circuit diagram would certainly make life easier.Depends on your unit. The early production units had a grounding error on the pcb that required cutting a trace on the pcb to fix. I think most of those were sent back and fixed by Joe, but if yours happen to be an unfixed one, the hum should not be developing; rather, it should be there immediately at turn on. Solutions to that (with pics) are available early in the thread.
If it's a later unit, then that is fixed and you have some other issue. If it actaully develops over time rather than being present immediately, first isolate it to the actual amp as elwappo99 suggests (remove all inputs), and if the hum is still there I'd suggest swapping the tubes out before doing anything more drastic.
New Headphone amp are under developt. It is upgrade from Jade.
12AX7 x 1 , 6AS7 x 2 , 6AS7 Loading by CCS. Top model will use Reed relay base 42 steps, step attenuator. It is 2db/Steps. Very low pop noise. It may be will release around 2 ~ 3 weeks. Other hybird Jade also will comming soon.
