Sophie, I’m not saying you can get a McIntosh Mc275 for $3500, but If there is a chance at all that you could get close, call Mike Sastra at Audio Classics!
Also, not sure of your speakers or if 75wpc - 90wpc will work for you.
This is a special amp indeed and new they cost around $5,000. Used ones are cheaper. McIntosh has been making this amp for decades! It is built like a battleship and will last forever, very reliable too.
