I've recently seen some topics regarding the modding possibilities of the M-Audio Transit. From what I've seen, the three possible areas for improvement are:
1. The two 10uF 16V caps in the headphone output (bottom right)
2. The LMV722 op-amp located next to those caps
3. The 100uF 10V cap next to the power supply
(biggest one, next to 3.3V regulator, at the bottom left)
Because of those thread reccomendations, I was thinking to change the two 10uF 16V caps by black gates Nx 22uF 6.3V, the 100uF 10V cap by a panasonic 470uF 16V and the LMV722 opamp by an AD823 (or AD822 if I don't have any other choice).
The main differences between those opamps are:
- LMV722: Dual channel, supply 2.2V to 5.5V, supply current per channel 0.90 mA
- AD823: Dual channel, single supply 3V to 36V, dual supplies ±1.5V to ±18V, supply current per channel 4.2mA
- AD822: Some similarities to 823, worst performance, 0.90 mA
Could you please give me your opinion about it? (I haven't seen any feedback from anyone that already did a Transit mod). Would the AD823 be OK for this application? And the caps? Also, any idea of the best method to de-solder the SOIC op-amp? De-soldering is also tricky, but I can solder SMD components easily.
Thanks.
EDIT: All mods done long time ago, if any is interested in info PM me
