Average price for a lenco gl75 made in Switzerland

I am looking to see what this is worth and if I should sell it. I would like to keep it but I am short on cash.


It's made in Switzerland and works. I also have that amp.

Any help appreciated!
All Lencos were made in Switzerland, once upon a time.
Ah right, I heard there were too versions, one being made in France(?).

I also have an old Amstrad 5000 amp.
