Hi everyone, I have a K-250 bass head from 1972 I believe with the matching B18 cabinet both in black Naugahyde. They're both in great condition, and I recently replaced the speaker to a new Carvin PS-18. The cord has been replaced with a three prong plug, but everything else is all original as far a I know. Was hoping to get $500 for it. Located in Raleigh, NC. Happy to send pictures and receipts of work done on it.
