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!

Ah right, I heard there were too versions, one being made in France(?).

I also have an old Amstrad 5000 amp.
