Hi Tony,

Thanks for the other suggestions.

I've checked out the HIjack behaviour, and it's definitely set to 'normal'. I'm going to install a diode internally today, to see if this helps.

The other thing I'm considering is that temperature could be a factor. I've only actually investigated the problem, once I've seen it happening. This usually occurs after a long drive, when the internal temperature of the Empeg (as seen by Hijack) is in excess of 40 degrees. I'll run some cold pull tests, to see if the behaviour remains the same. If it does, then I might think about putting a fan in.

Thanks again,

Andy.
