One of the all time greats! The construction and
quality of this amplifier rivals anything out there including the
Pioneer Spec 2 and Spec 4. In my opinion, Sansui was the leader in the
70's when it came to building the very best. I'd stack this amp
up against anything old or new. I even prefer it to the Sansui
BA 5000. Altho the BA 5000 has more power, you need a crane to
move it's 100 lbs. (At least if you're getting to be an old fart like
me). I'd rather run two of these in mono or use a JBL
dual mono amp if it came to that kind of power requirement. These
units have been steadily appreciating in value over the past 5 years. You can get into this BA3000 for:
See Equipment List
The front end is a class A driver which insures
optimal sound reproduction as the amp is always operating in the
linear region of the transistors. Get it clean up front and it stays
that way thru the rest of the amp.
A Torodial transformer with separate windings for the
dual positive and negative power supplies gives clean power to the amp
circuits. Sansui started as a transformer company and their
expertise was put to good use in the power supply section. Two
huge 22,000 mfd capacitors insures plenty of power when the music
needs that oomph for the high-power transients and also for flat-out
6 output transistors for each channel on huge
heat-sinks shows this thing is vastly overbuilt. Just the way I
like it. I've read that this amp can hit almost 600 wpc during
short bursts and is rated at 170 watts per channel RMS into 8 ohms.
You can bridge the outputs for 340 watts mono into 8 ohms.
Heavy, high quality Sansui Definition Series unit, no
plastic crap. Was $1200 in 1976 dollars ($4800 today).
Units have been gone through, cleaned, adjusted and lubricated. Look
Each unit has a couple of very minor
scratches on the top plates. Most of these units were one-owner systems.
