Does anyone have an idea what Sansui B-1 in excellent condition is worth?

Really interesting amp. How does it sound? I havent seen one. I think unless you find an enthusiast it would be hard to get more than $400 for it but that's really just a guess.

A few things to consider: 
- 80s power amps arent in vogue right now even among the vintage set. There are some great deals on nice components from this era for that reason such as yamaha m series power amps. This could change in the next few years. 
- this unit is heavy so local pickup is probably best. This could limit your market or price if you ship it given the shipping cost. 
- as noted its pro or semi pro which again puts it into a specialty category. 
- i think it has a large fan? If so many dont like that. 

Amp sounds great! I currently have it powering the high frequency channels on my B&W 808's....exceptional clarity. I tried posting a pic of it, but it won't let me. Someone offered me $3K for it sight unseen, think I'm going to jump on the offer. 

If you get $250.00 you would be lucky good luck.

Hold out for $6,000...it definitely happen.
