Default DBX 576 complete upgrade. Advices?

Hi diyAudio,

the recent readings of the forum has taken me into the mood to try my first diy mod, you guys have turned my curiosity on

I want to upgrade my DBX 576 micpre/comp channel strip.
I've planned to change tubes and opamps, and I want to add input and output transformers.

Tubes: I've picked up 2 Telefunken diamond mark smooth plate 12AU7 to replace the stock tubes Philips ECG 8739ADX.

In/out transformers: I'd like to add the Lundhal, but I still don't have enough know-how to pick up the right ones;

Op-amp: in the schematics I read that 3 different types of opamps are used in the stock 576:
- TL072CDR
- NJM5532D
- LM833D
Can you please suggest good replacements for each of the 3 models?

Here the schematics of the DBX 576: ftp://ftp.dbxpro.com/pub/pdfs/discon...0Schematic.pdf

Any help would be highly appreciated.

Thank you
