Did service and repair on this little beauty.Came with short bridge, blown fuse...Worth upgrading all power diodes to higher rating ones. Recapped with Nichicone FG.Very beautiful sound , typical for Sansui amplifiers from this era..

A very good entry level amplifier, perfect for small systems like a bedroom or office or even for a compact dedicated vinyl setup. Pair with efficient speakers if you plan on filling a larger room. If the price is reasonable highly recommended you pick one up.

Nice little amp - sounds great, perfect for small set-ups, don't let the low wattage put you off. Quite loud, well matched with small / efficient speakers. Easily drove large speakers too. Grab one if the price is right - undervalued amp

Love this guy. I have two of them…both with scratchy selector pots and cold solder joints going on inside…hoping to restore them to their glory.
