You're the only one...
I did leave space in the layout to add feedback resistors, which would tighten up the channel balance.
Ok..(I thought that some Imbalance is normal on this Amp(So I have misunderstood this)) :/
If I want to add feedback resistors in this circuit where must they placed?
Before I consider to add feedback resistors in this circuit, should I resolder the solder joints from the Input Tube Socket and from the High Current PC Boards?
