HT-Dual problem

[Jonaspls]

So when I plug the power supply in, both channel lights come on.
No sound or anything coming back to me. Any ideas what's wrong with it?

hi Jonas,

before taking it to a tech - I would try swapping the tube out. 12AX7's should last for ages, but it's not uncommon for them to turn against you! I had to replace mine not long ago (lost channel 1, but channel 2 was fine - fixed with a fresh tube).

The signal goes through the single 12AX7/ECC83 on both channels, so fingers crossed, this could fix the lack of sound/signal - It's a quick and easy DIY job (check you tube for the bottom entry method of replacing the tube), and will only cost the price of a new tube (or you may have a spare kicking around at home?).

If it's not the tube, then you will (unfortunately) have to take it to a tech, but at least you will have a nice new (upgraded) tube that you know is good.

Not sure why both LEDs would be lit ....but it could all be related?

Hope this helps. Good Luck

Thank you very much for the quick and helpful reply Paul! Ok then I'll give it a try, I'm sure I have a spare tube at home, if not then it's off to the techs!
