This is my first post. I have an old 1960's vintage Showman Amp, rewired for stereo as a preamp, and an Alembic cabinet with 2 15 JBL speakers that I would like to sell (we are downsizing). I bought the Showman used in 1971 (or so) and the Alembic cabinet new at the same time. Neither piece has been used since about 1978, but the 15 speakers need to be reconed. PM me if you are interested.
