I have a new (1.5 months old) Super Sonic Twin. I turned it on the other day and could get no sound to come from it. Power comes on, but the tube indicators on the Automatic Bias are NOT on and the Warm, Normal, Cool indicators are all ON. Any idea on what this tells me is wrong?

I have the 60 watt and the 100 watt twin and love them both.

I am only offering a suggestion as I have no personal knowledge about your proble.

If I had this happen to mine, I would reseat all of the tubes and see if it fixes it.

If reseating the tubes doesn't work, call an amp tech.

For an amp purchased new and only a month and a half old, I'd notify the nearest Fender authorized service center. Immediately.

Probably the best choice, but if the amp received rough treatment during shipment, checking the seating of the tubes might save a trip to the shop.

Indeed. It's certainly worth trying.

Of course, most freight carriers and UPS are usually very gentle handling delicate items. :roll:
