I have two pairs of RTA12Bs here and need to get rid of one. One is from 1984 and has a green circut board and came with the silver faced SL1000. I have also seen them with the later Peerless.
The other one has the brown board and is from 1981. Does anyone have a n RTA 12 or 12B with the brown board and Peerless tweeter and if so what does the back of the tweeter look like?? Are there numbers on it??? thanks,keith
