Dimitri was kind enough to send me some measurements of the unit showing it to be somewhat out with regards to its RIAA response.

R12 should be 1k5, R9 left pin should be connected to ground instead the 4580 output. And this is only for a start

Hello!
I'm thinking about modding or improving the Phonobox. I have some OPA604, 134 and 637 in my box, are they drop-in replacements? There are some ceramic caps on the card, too. And elcos ![]() Earlier some people suggested there were some "faults" in the circuit, is there anything one can do? What about increasing the output level a bit? Got some experience with modding CD:s so difficult jobs don't scare me ![]() Tom |
