The whole system, minus the CD changer was offered when I responded to the post for the DQ-10s, DQ-1W and LP_1 crossover. For the extra, I was all for it. I bought a DC-300a in 1974, FTC stereo power rule implementation day, and can not remember what I did with it. Nice to have this pair. They are newer, 1980, but one nice thing is the handles.
I'll spend a lot of time cleaning but the tuner, 1993 Onkyo, crossover and preamp (Yamaha C-4) are all clean and ready to be hooked up and evaluated.
DQ-10s get very dirty because of the shelf on the back under the cage. These are horrible. But the grilles are off and cleaned. I have a good bit of work cleaning the speakers. Then they get a recap. Stacked Dahlquists, Crown PSA-2 power and a DC-300a on the sub. Hmmmm.
