Hi noko,
Thanks for your answer. I'll try to do a photoalbum because my PE 231 it's disassembled, but I'll recover for give us an idea as it is. First af all, I'll explain a little history about it.
I was not considered in this post that my PE is an old record player that was built in Spain, and sorry for this.
This was numbered with serial number 235 and chalkwrited into it and manufactured in Barcelona. It's a really portable model. It includes a 1,5 V battery box in the rear and this is not habitual in this systems (know it for me, of course!)
This player belonged to my aunt when she was young. And was a great party performer few years ago. I know its existence since I was a child. I have tried to date but I think it's impossible, I calculate that was bought near 1967 but it could be a wrong year.
Before I disassembled it working right, but with some wrong adjustements.
Tomorrow will continue ... and will post the photos I have in this moment ..
And nice you answer me ..
Alfred
