That was about 1980. TW's/Son sold and replaced with Quad 57's and Bedini 25/25. Mogami still in use! And remained so when I got the KLH Nines in 1992. The Nines/Mogami combination lasted until 2015. I lost the Mogami when I moved south that year. But saved the Nines! Now have 6 ft pieces of RCA all-copper 14ga zip connected to the Nines/Carver 15CB and Ohm Sound Cylinders.
