Could be a fuse, or a connection from the power supply to the circuit board. Where is this installed? Has it taken any abuse? If it just sits idle and doesn't move, it could be a fuse, and it could be a circuit board. The biggest problem is it's TEAC...haha, just kidding.

Hi, using my amp for a long period on new years eve and the amp suddenly died. I've changed the plug fuse and checked internal glass fuse, both ok.Cant see anything obvious I.e. burning or over heating...

There's only one way to check the transformer and that's with a voltmeter. If there is mains going in but nothing coming out of the secondary, then that fuse has gone. They are not designed to be replaced and Transformers are what the trade call 'Safety Parts'. So they have to be replaced with the same thing. I would contact Teac and find out if they still do make them or where you can get one from.

Is the Teac RW-H300 a unit that can be repaired easily?

It would depend on a zillion things. Only a hands-on technician could answer it. Diagnosis and Labor costs can be open-ended.

Typically, modern electronics is not economically repairable. At $355 on Amazon for a new one, it could easily be cheaper to replace than repair.

Fault must be in preamp, I got it wrong! TEAC A-H300

Just curious, what preceded this? Sudden spontaneous failure with no manual action associated? Is the Tape Monitor activated?

I don't know how valuable your speakers are but you're hitting them with max power and distortion when you get that bang. I'd use cheap headphones for the troubleshooting phase.

I found the thread of one of my speaker cables was touching the backboard of the amp and shorting out - problem solved!
