Hi All!
I picked up a near mint condition Music Hall Mambo integrated amplifier from an acquaintance's mother. She used it but sparingly, which is evident by how clean it is. I got it for a reasonably good deal-- $550.
This is a 50lb Class A integrated. It's really nicely made, but I'm fooling with the idea of making it into an upgrade/modification project. I know that Underwood HiFi and maybe Parts Connexion were offering modifications that cost near $1,600. See Mambo | Underwood HiFi.
I popped it open today to poke around. Here are some photos.
Any advice on where to make modifications?
I was thinking of figuring out the following:
Swap two caps on gain signal --or at least what I think is the signal
Change electrolytic caps from Elna to Mundorf M-Lytics, etc.
Change out the Burr Brown 2604AP OP Amps (x 5)
Any help would be greatly appreciated!

Let's see if this makes photo 1 above larger.
