What to do with dead equipment

Thank you.  When my preamp started acting up again, after re-tubing, I tried to reach him via email several times.  He never responded.  I'll try again.

As a last resort, Staples office supply will take electronics off your hands for no charge.

Sell it for parts cheapish or get it fixed. There is probably an audio tech near you that knows his sh.t. It’s not rocket science so doesn’t necessarily need to be the manufacturer that fixes it. Don’t throw it away unless you like to throw away money. 

I have a local guy that’s done an Odyssey amp I blew up due to my dumbassness and added a preout to my tube integrated. Fairly inexpensive. 

Sell the amp “as is” and hope a DIY hobbyist picks it up and attempts to fix it.
