Today I was given a pair of Norsk Audio Baltic 50, 3-way, 150 watt spreakers. They were made in Latvia in 1990 & have Russian wire-wound potentiometers.
But one is totally dead. It tests 8 Ohms but I didn't find anything obvious wrong inside.
Everything in there is super robust.
So why no sound? My Marantz 1030 amplifier is in top condition.
Can anybody tell me why its not working? Or does anybody have a schematic drawing of the crossover? Or such problem experiance with other speakers?
It looks like the "classic" Radiotechnika S90.I would check the speakers separately (impedance measure) ,wires,crossover soldering.
Good luck to repair!
It turned out to be problems with the connection jacks on the rear of both speakers. Now both speakers work beautifully!
