Realistic Stereo 40/A
I put this advice to share the information I gathered on this amp.

Defective bought for next to nothing in a flea market. it is only opening I discovered that there is much beautiful people in there: four 12AX7 and EL84 5 1 5AR4! He was down? Not really just change a 12AX7 to get more than 40 years!

It's heavy! As the solid actually more! All welded point by point by hand! I intend to use it with bass guitar and keyboards! with a booster I'm sure it'll rock!

If you have a chance, Go ahead close your eyes! It's not that I knew previously Realistic! (We are far from useless stuff and plastics usual brand!)
