Pre-amplfier - No sound if switching from Tube to Tube+ mode

Question: When I use the iCan Pro in pre-amplifier mode and go from Tube to Tube+ there is no sound but there are red LEDs flashing. In addition to this if I start the unit whilst in Tube+ mode it is OK, the solid-state mode is fine.

Answer: Red means the DC protection has engaged, possibly one tube is bad but the tube determines the DC operating condition. If they're outside the "safe" zone the system will assert DC protection. There are four tube sections (2 channels X 2) and if one is "borderline" it could cause the behaviour (pre-amplifier mode from Tube to Tube+ doesn't switch correctly).
