Hi,

I have a Sansui B-3000 amplifier. And I blew it for the second time in a few hours. I was not even playing loud. The first time an IC gave up, the second time I blew many parts because a smal resistor broke down( so told a HiFi shop) It could have been bad luck but the cause of the problem may be found in the resistance of my Canton speakers. My amp was build in the late nineties It`s not a 1970 BA-3000.

The back of the amp says "impedance 8 to 16 Ohms" and so does the manual. But I can connect two sets of speakers. So if I use only one set of speakers I could use 4 - 8 Ohms speakers. I checked this with a local HiFi shop and they could describe the amp immediately and said that I could use a 4 - 8 Ohms speaker safely.

So I did and after about one hour and a half the amp was ruined. Repairs are about € 50.00.

I do not want to blew it again but I cannot find anything useful on the internet.

I wrote to someone who actualy owned a B-3000 used Alexis Monitor One speakers together with other speakers but he did'nt know exectly the resistance his speakers.
I checked the Alesis Monitor One he used and I found they are 4 Ohms too.

So I would line to know if the Sansui B-3000 can work safely with my Canton 4 - 8 Ohms impedance.

This afternoon the HiFi shop called and told me that they had repaired the amp. I really do not want to damage the amp again.

Regards,
Steven Wartena
