Looks to me like a phono pre, with the // transistors and some hi-Q caps probably for RIAA. No idea of the brand though.

..it is shown as line preamplifier and works with dual voltage 24V . It is a really strange one PCB , has a total of 40 transistors for a preamplifier

no, the seller tells me does not have a name the PCB . He tells me to have bought in Germany a few years ago ... Anyway, I watched the service manual marantz ma9s2 , actually the preamp section is very similar to this PCB . My doubt is , can a transistor preamp with 40 ..... who know how it really is intriguing .... I am tempted ...
