Where is best to sell old Brociner tube amp?

Yeah. I'll help keep an eye out for that. What I suggest is once you find this site, if they happen to charge to list items for sale, just post in their forum looking for a recommendation of where to sell. You know, like a tacit ad without having to actually pay to list. Just mention the make and model # and wait for offers to flood your inbox.

How did Inheritedtubes post get past the moderators?

And surprise!...he's a new member, and it's his first post.

Inheritedtubes, how did you get as far as to asking this question on here without realizing what website your on? Did you not notice the 'Buy' and 'Sell' links at the top of the page?

It's frowned upon to try and pedal your goods without playing by the rules. Just spend a little more time reading up on how to post your amp for sale in the classifieds and play by the rules please. It happens all the time but the people on this forum adhere to the policies of the website and expect everyone else to as well.

Good luck with your sale.

Selling this unpopular amp could be challenging. You can sell it here, ebay or cl-locally, but the main point is that you should learn first about this amp:
1. What tubes are there and how many per each channel?
2. What's under the chasssis? What kind of resistors, capacitors
3. When it was manufactured from...to and where?
