RND Portico 5033

[GreyboxAudio]

I've finally acquired a 5033 and here are some PCB shots. It will take a while before I can come up with a schematic, but I've already made good progress with the BoM. I wouldn't be suprised if the EQ topology is related to the Amek Mozart RN. Interestingly the EQ gain stages seem to be discrete and are built around the following six transistors: PN4250A, 2N5210, 2N5087, (2x) A1085 & 2N5209. There's also two BD437 transistors, presumably on the output. The ICs are all NE5534. Let me know if you have any questions

Would love to see a schematic for the discrete op amp blocks. Looks similar to the topology (6 transistor) in other RND stuff, have always thought they sounded good.
