My M60s have not been used for nearly two years, but have been brought into service subject to a sale.

On powering up, one of the tweeters does not immediately work, only cutting in after a minute or so. Re-powering up repeats the manifestation.

After that appears to work fine.

Any ideas re what the issue may be?

Thanks
