I do not have a pair of 300s. I have a 150 and so far it has been reliable. If you're buying new, I wouldn't be worried about it at all, if buying used, that'll depend on whether the owner has had any problems with it like any other gear. Anyhow, tenor's service department is up and running. Check the website for details.

Have heard of these amps failing- Should I be concerned buying a pair of these amps-With tenor belly up at the moment and the future unclear how bullet proof are these amps- I have also heard of updates by tenor- Anyone know what they are and how they affect the amp- thanks-K
