Schiit Freya +

The buyer has sent a video  of the crackling noise and now says that's gone. Now the volume is making a noise. I've offered to refund him but he wants to send it schiit for repair. I just wonder if the delivery man dropped the box although it hadn't any damage. 
 

I thought the freya was an amazing piece of gear for the money, you couldn't find a used one in the world at that time 2 years ago,  now there are quite a few pre owned for sale.

I would offer to take it back again and if he still wants to send it to Schiit for repair, then that is on him. As for the volume making noise, it does. Is it coming over the speakers or just the relay clicking?

Brunomarcs I have one. It’s the tube that makes noise, the jj don’t make noise on mine. Probably Schiit will honor your warranty as long as you let them know, They have good costumer service.

Tell the buyer try other tube before sending it back.

The buyer wants to keep it, I've offered to send him a refund twice! He's contacted the factory is all I know. They said to try new tubes. I think he's perturbed I sent out an untested unit, It played just fine a year ago. I should've plugged it in and made sure it was working. I even doubled the package for safer shipping.  Like I say I won't guarantee a tube anymore on a sale of a unit. I'll  have to make a restitution of some sort.
