The Sansui 8080 DB came to market at around 1975 and lasted until around 1978. It was price at about $650.00 and was a popular model for Sansui. It has the classic styling of a mid 1970's receiver with a black and brushed aluminum face plate and dark dial meter with blue and white meters. The DB version of the 8080 of course had built in Dolby noise reduction.
The Sansui 8080 DB is essentially the same stereo as the 9090DB but with 85 watts output per channel instead of 110. It's a really well built receiver. You'll hear some talk about which one sounds better but they are almost identical inside.
Here is what one user said about the two receivers:
"The 8080DB uses exactly the same driver board as the 9090DB so the only difference in the amplifier section is a little less power and 4 output transistors. The amp sections should have no discernible difference in sound. They also both use exactly the same pre-amp section except for the crossover/defeat switches in the tone controls. The circuitry is identical otherwise. Since you can't defeat the tone controls on the 8080DB, there may always be a little coloration to the sound because there will be some variation to where the 0 point is on the tone controls. As a result you may always be adding or subtracting a little tone."
The 8080 DB is heavy and weighs in at around 46 pounds.
Here are some of its other features:
- Built-in Dolby Processor
- Triple Tone Controls
- Four Accurate Meters
- Frequency response: 10 Hz to 30 kHz
- Total harmonic distortion: 0.1%
- Damping factor: 30
- Input sensitivity: 4mV (mic), 2.5mV (MM), 150mV (DIN), 150mV (line)
- Signal-to-noise ratio: 70 dB (MM), 80 dB (DIN), 80 dB (line)
- Channel separation: 50 dB (MM), 50 dB (line)
- Output: 150mV (line), 30mV (DIN), 0.775V (Pre Out)
There are some issues known to this receiver. The driver board, RF power supply board and Dolby board all have common problems. The driver board has problematic resistors while the RF board runs very hot which can cause problems and the Dolby board tends to get cracks in the solder traces. The DB board cannot be bypassed and all signals run through it so if it has problems then your receiver will not work properly.
Vintage Sansui receivers have always been popular and, therefore, somewhat pricey. The Sansui 9090DB can sell for over $1300. If you don't want to spend that much but want performance that is just about as good then you should consider the 8080DB. It sells for around $500 in very good working condition.
