re: GFA-5500

Thank you so much for these manuals. I have had 2 amps from Europe for a very long time and asked several technicians about converting from 230VAC to 115VAC. The service manual outlines the process and was very clear and easy to download from your site.

Now, why couldn't the tech just have told me this? I have an idea, but I'll leave that and any criticism to others.

Again, my thanks for a great site.

Thank you for the Adcom GFA-5500 Service Manual.
However this PDF appears to be missing pages 8 and 9, and according to the table of contents page 9 has the schematic. If someone has the complete manual it would be greatly appreciated.
Thank you.


Thanks for spotting that. The description has now been changed.
