Does anyone have any information or opinion on this model of Sansui amp? Does it compare to the B-3000?
B-2102 amp

Regarding your comparison- do you mean the B-3000 or the BA-3000?(there's a huge difference between the two).
The B-2102 is a very good power amp, 200 Watts. Circa mid-latter 1980's with classic-style Sansui logo (as opposed to newer logo that went into effect in late '87), matching preamp C-2102. Before that, Sansui made a B-2101 amp and C-2101 preamp.
Perhaps you can think of the B-2102 as a power amp version of the AU-G99X integrated with some extra watts.
The B-2301 power amp (which I own, along with the C-2301 preamp) is Superb- 300 Watts, its the only amp that I put in approximately the same league as what you see in my avatar
Sansui also made the B-2302 in the early 90's (with C-2302 preamp), also 300 Watts, new Sansui logo, tremendous power amp, very hard to find any for sale nowadays, and any that would be, would cost dearly.

Sansui B-2102 amp
Thanks. I own a B-3000 amp. What is the difference between this and the Ba-3000, which I understand was made in the mid 1970s. I own a CA-3000, which has an intermittent right channel that has escaped repair by a reputable electronics shop. I have read different postings in different forums about owners of AU-717 amps with intermittent channels, and there attempts to chase down the cause, which despite cleaning different switches and relays, is never 100% successful. Does anyone have any ideas as to the possible cause of this problem with older Sansui gear? Could it be a cold solder joint on a switch, pot, or relay that escapes detection, resulting in the various degrees of volume loss at different times that seems to be a common factor in all these situations?

The B-3000 is nowhere in the same universe as the BA-3000. The B-3000 is much more cheaply made, both externally/internally. I would think you could see that just by comparing the B-3000 with the CA-3000 preamp you have. Doesnt the B-3000 look like a cheap piece of plastic to you and the CA-3000 built to a much higher standard? The B-3000 is a power amp designed for modest use- I think I already explained it before not that long ago on this forum when I posted the B-3000 rack system photo, if you havent seen it, you can locate it by doing a Search in the Archived messages. Or see my previous comments about Sansui rack component systems which I have also written about before on the www.sansui.us Message Board (which is in the Feedback section there)
As for the CA-3000 channel problem - Try moving the Volume control up real high, and then back down, back and forth quite a few times, and see if the channel comes back. Of course- to protect your ears, when you turn the Volume knob up High, activate the Mute switch, as you can see, the Mute has two settings, putting it on -30DB should enable you to turn the knob real high. In my case with the CA-3000 I have, when I did this, the channel came back and so far its been working ok. I advise to be a bit careful with the Volume knob, it can come loose like it did with me if you get too vigorous in turning it. It might depend a little on the degree of tightness/looseness feel that your particular CA-3000 has. If it comes loose, then you need to tighten it with an Allen key. (The Volume Knob on the CA-2000, AU-11000 & AU-9900 are better than CA-3000 & AU-20000 type).
As for the AU-717, the one I have has been working fine. But there are alot of switches on the AU-717 and after 25 Years, its not unusual for some of them to act up, including the dc/ac coupled switch in the back. Of course, there may be other issues like cold or loose solder joints. Quad Bob is currently restoring one, so perhaps when he's ready he might be able to provide some info about the AU-717 in this regard.

Thanks for the information. There is no doubt that the CA-3000 is much more expensively constructed. It also sounds fantastic, and looks surreal wiht the green lit meters. The B-3000 has a plastic case, but it is a powerful amp, seems to have a neutral, transparent character,and looks great with the C-1000 preamp that sits on top of it. It is not as impressive a unit as my AU-D9 or AU-G99X, but is a great unit for running the front speaks on my home theater. I have seen B-1000 amps listed on Ebay, but never C-3000 preamps. Does anyone know if there wa a C-3000 preamp made?
I will take a look at the volume switch, and see if that is the problem. If Quadbob has any new information on this topic, it will be great to read what he has to add.

I dont think there's a C-3000, just a C-1000 preamp that would go with either the B-3000 rack system or the B-1000 r.s.
For basic H.T. use as you descibed, the B-3000 should be satisfactory. The C-1000 remote for the Volume Control is a convenient feature to have.
If you think a pair of green-glowing meters on the CA-3000 are surreal, imagine what 6 of them are like- thats what I have with my CA-3000 driving the two 'Monster' BA-5000's :nutz:

The arms race......
What about the C-1000 preamp on top of a 1200 watt two channel concert sound system amp driving Cerwin Vega AT-15 speakers for the home theater left and right front channels? This is going to happen next week. Did you have to do any restoration to the BA-5000 amps? I have a buddy who bought a BA-5000 amp brand new in the late 1970's, and it developed a problem 2 years ago. he has been waiting this long to get it repaired, and is still waiting for it to be fixed. He is stuck for an alternative in the way of another electronics repair shop. Any ideas?

I am interested to know more details about your friend's BA-5K. Have him email me.
