Default OPA549 Amp Finished

I've just finished a new amp with OPA549. I must say that I'm very satisfied with the sound. It's very open and well defined in bass and in high region.

Here are some photo (not so good) :

Nice work, the case!

Is the front real wood or MDF?

If MDF: dont hesitate to apply shellack! Gives real great results, but must be learned (can be removed with alcohol...).

Franz

P.S.
What capacitance do the orange caps have?
