Hello. I' just got this component, and I'm not sure if it's a radio, a preamp, or and amplifier. No brand name or model. Can someone identify it please? Thanks in advance for your replies.
Can someone identify this mistery... ¿amp?

Welcome!
It's an integrated amplifier but if you didn't know what it was, why did you pick it up?
Not trying to grief you, just curious!

Because if (as my instinct told me) is an amp or a preamp, maybe it's worth restoring (the owner thought it was a radio). But to do it, I need at least to know the brand, to start looking for the diagrams.

You don't need schematics. Just replace all the capacitors and any out-of-spec resistors and it will bring it back to life.
Maybe a schematic is needed to see what the missing tubes are but most of the time, they are 12AU7 or 12AX7 tubes. Could be 6EU7, 7199, 6AN8..............

I thought the same. It cost me the equivalent to $25 (I'm in Perú). It's a bargain even as decoration.
The screws holding the sockets and such in make me think kit. The Sprague caps are US-made, the grey caps are Japanese, and the resistors I don't know. They don't look like Japan or European, but they don't look US-made either. I'm not familiar with the look of South American components, so it may be a local brand for you. With no brand name its hard to guess who made it.
probably going to have to reverse engineer it and make some guesses as to what exactly it is. Appears to be a 6V6 integrated amp, the missing tubes you can probably narrow down based on how the sockets are wired.

I'm thinking some sort of console amp. Bi-amp mono for the radio, stereo for a turntable. The output trans. look to fit the chassis as original so there could be a low and higher freq. setup for mono, split for stereo. Not really seeing a selector, maybe a separate preamp? Looks like is was a quality piece though.

Thanks for your help. I´ll let you know if it comes to life.
