Is it possible to remove the phono card from a CTA receiver and make it into a stand alone phono amplifier. I’ve got an old CTA in bits and have traced the flying leads that are the turntable input to a PCB at the front of the receiver. It’s got audio in (L G R) & out (L G R) and an additional red lead off the main PCB in the receiver. Is this card the phono amp in its own right or is this the XD bit of the CTA252XD and therefore works on the phono input in addition to gain & equalisation provided by the main pre amp board (in which case this idea is probably a no go)?
I guess it is possible, but to what effect? Please contact Nytech and ask for a restoration/repair of your CTA. I think it would a shame to dump that item, since it is a classic iconic design with a good sound which would not be out of the part even today. The phono part is in my opinion the least interesting part of it. Since the early days of Nytech the power amp has proven the test of time, the two transistor phono stage did not.
