Hi all,

I have one of my Lab 1s going in to protection mode. Red light turns Green for a second then back to red.

I have disconnected the tweeter but no change.

Guess it’s an amp issue, any ideas anyone or is there anyone who will repair it ?

Thanks Steve.

Disconnecting the tweeter doesn’t help. A ceased tweeter is the same as disconnecting it. Measure the impedance of the both mid and tweeter. When these show an impedance of several ohms less than 10 ohm, then the amplifier is faulty.
In case of a faulty amplifer, I can fix these in combination with maintenance to prevent other often strange symptoms.
