Need help in selling amp&preamp

This is the forum section, for sharing information. You should looking into the ad section and place an ad there, this is not a marketplace. Click on "Sell" and it should walk you through the process. If you are not sure where to start pricing, perhaps you would be better suited to start a low or no reserve auction instead of a regular ad.
Good luck.

place a for sale ad

I would bring to a local tech and have them check them out and make sure the working condition is tight and if any of the caps are leaking or need to be replaced. That's helpful and valuable info for a buyer. Search online to see what a fair asking price might be for the condition and set-up either a regular add or try an auction here. Good luck!
