The Acoustic 371 system was my dream rig in my teen years. I had a catalog pic of the on my wall like amp porn.
I purchased the 301 cab new in 1973. I was 11th grade. All original. It has a single Cerwin Vega 18” rear facing speaker. 4 ohms.
The head I got a few years ago. I refurbished the head case with Duratex. It’s a 1974. It can use two cabs and will do 365 watts at 2 ohms.
