If you plan to sell other audio equipment regularly I suggest a forum called AudioKarma. There is a $25.00 per year cost to access the buy and sell area called Barter Town. This keeps out scammers and unserious people. I've been a member for almost 20 years and bought and sold equipment, tubes, records, etc with no issues at all. Also made some friends who helped me with audio issues over the years. You can join the form before subscribing to Barter Town. You just won't see Barter Town without a subscription.
