I have two Ramko Research 5 channel mono audio consoles and one McMartin console for sale. I have checked the Ramko consoles and they are working. Filter caps might have to be changed and other maintenance performed. One of the Ramkos has seen a lot of use and paint is worn on it and the headphone switch is missing. The other is in fair to good cosmetic condition and appears to be complete. Both have residue from stickers on their faces.
I can provide pictures in you would like, just send an email to me. 73 Jim de W5JO
