I have a pair of Sansui 1000 tube receiver output transformers and I thinking of using them in a SPP. As far as I know they are 3.2k impedance. Any thoughts on using these with the 6cw5/el86 tube? Also the Antec IT200 is out of stock any other suggestions for a power transformer? Also, would one these Antec work under a chassis top plate or would it get too hot? Hiding it inside would solve the funky looks issue.
