He bought me a very rare radio, the speaker and some valve are missing, but I do not know what model it is, if someone knows, please, I appreciate it, and if you have the manual or the diagram, but without the model, nothing, greetings and see if you can. help since in the back it does not put anything except below fonolita will be the material for photos.
Please post in English so others can read and help you

If you could remove the chassis and tubes that would be helpful. Please post the tube numbers. I think I see one that sez 2A6. One of the sockets has been changed behind the power transformer which probably was an 80 tube. The others maybe 2A7,58,and 2A5. A pic of the top and bottom of the chassis out of the cabinet would help too.

Hola locuspiolin.
Es necesario que pongas los códigos de las lámparas y unas fotos del chasis por arriba y por abajo para ver si encuentran algún esquema que te pueda valer de ayuda.
Encontrar un esquema generico con las válvulas que lleva tu radio es más o menos fácil.
Encontrar el esquema exacto va a ser muy dificil, por no decir imposible.
It is a BC/SW spanish brandless kit with early "american" tubes and tone contol.
You need a generic scheme.
Without a doubt.
Made by somebody in late 40's or early 50's, with early 30's tubes and fixed in 50's with a B8A base.
For AZ41 (4V direct heating rectifier) or EL41 (power pentode) ?
The cabinet's style is from late 40's, early 50's.
The speaker shurely is electrodynamic without anti-hum coil.
It seems it was built with the tubes what they found by the drawers ...
It is very weird using tubes with 2,5V heatters at early 50's.
I think they could have used 80, 42, 75, 6D6, 6A7, or maybe octal tubes (5Y3, 6V6, etc).
Or better, Rimlock tubes with base B8A (AZ41, EL41, EAF42, EAF42, ECH42).
It isn't wood or bakelite.
The cabinet is really made of plaster or white cement or ceramic like bricks with something else inside to reinforce the structure.
Maybe wire netting or/and some type of bandage.
And the front is made with a mold to give it a snake skin look.
Phonolite is a rare type of volcanic stone:

This phonolite cabinet is not mine, pics found in Internet.
Look at Rimlock base B8A tubes:
