I saw a Q-3535 for sale in Germany about 3 or 4 years ago. Super minty and restored...and maintained annually. I can't remember what it sold for. I may have it written down somewhere. It looked beautiful, like new.
There was one other for sale on eBay Germany, or USA. That was 5 years ago plus.
Think I've seen one for sale on Yahoo Japan a few years ago too. Maybe.
So 3 in 6+ years. Yes, it's a nice find! One every 2 years! Rare.
Also they guy from Germany selling the Q-3535 was also selling his SP-200 (I think that's the model number - the matching preamp). Seen maybe 3 or 4 SP-200s sold in the last 6 years. Again, Germany and Yahoo Japan.
Very Rare find!! Really very nice!!
The Q-3535 is just such a 'fine looking' tube amp. The matching pre-amp is really nice looking too.
I'd love to have both.
