Default Graaf GM-20

Hello. I'm a newbie, and have an opportunity to buy a '97 Graaf gm-20, for some 1000.
There are some scratches outside, and DIY bars under- it seems a dirty job, and there is some patina or something on metal connections... I'm attaching photos so you can check it out. Otherwise amp sounds good.
What do you think, what are future problems and is price for amp in this shape high?
Many thanks,
G.

Hello Gustaf,

You will probably need to get the amp to a technician sooner or later. It is the older version of the gm-20. They all have problems with the soldering around the tube socket. I think you will be better of with another and newer amp where the problem is solved. You should be able to get a very nice one for €$1500-€2000.
