For many years I have had a webpage about the beautiful GRAAF GM-20 OTL amplifier, and a lot of GM-20 owners has send me e-mails, giving me feedback and asking me about different things regarding the amp. So I was thinking that a blog would be better since it has the advantage that all of you that own a GM-20 or is interested in the amp can get in touch with each other.
So please add yourself as a follower of the blog.
I have not written a blog before, so I am learning this as I go.
I will slowly transfer the old webpage to this blog, and hopefully new stuff will be added. If you have any questions or feedback, do not hesitate to get in touch with me.
