Ah! Tjoeb Upsampler

Can't tell it better than this Dilbert strip:

Upsampler: top side

Upsampler: bottom side

Before installing the upsampler, both the output opamps (BB OPA627) and the DAC (TDA 1545) must be removed from their DIP8 sockets

"Ok, the photos are cool, but does it sound?"  Simply put, if you have a Tjoeb CD player, stop reading this and rush buying it! Even a tweaked Tjoeb player, with BB OPA627 opamps and Siemens ECC288, makes a quantum leap in performance with the upsampler, much larger than replacing opamps or tubes.
