Made down the road in Winnipeg Manitoba Canada by Gar(net) Gilles. Lots of them around here. Great low power tube amps. I assume yours is tube?
If tube, you want to have it serviced and it will work for decades to come.
I had Gar service my v4b in the early nineties. He was a cool cat with lots of great stories. He died in 2008.
