Assuming the DC spikes happen simultaneously on both channels (this can only be confirmed by you), I think the only possible scenario is the power supply, since that is the only place where both channels shares. This could be due to some instability in the ±15V regulation, however I think it is somewhat unlikely. If this is true, it is either the regulator is faulty, or there is some ringing between the capacitors, or simply a case of bad solder joint.
Whatever it is, I suspect mine has the same problem as yours.
