Yes, it does work, and is quieter.

> Hello all,
>
> I've been reading up on the nuvistaplug mod for the sp600. I'm not sure of 
> one thing. Does one buy a product called a nuvistaplug that contains two 
> 6DS4's plus 3 resistors and 2 caps?
>
> Or does one simply purchase 2 6DS4's and construct the circuit in the 
> article on some kind of tube plug in connector?
>
> Seems if I had a tube connector to plug into the socket, I could construct 
> this circuit. 6DS4s seem plentiful on ebay, but I don't know if one can 
> actually acquire the whole thing built.
>
> Does anyone know if this same circuit can be built with 6CW4's?
>
> Anyone done this mod? Is it a noticeable improvement?
> thanks
