Audio & keyboard buffs – who makes and/or sells low power stereo amps for keyboards – without the speakers?

Many electronic keyboards have stereo outputs. I have good speakers in the musical instrument, so all that needs is an integrated stereo amps of between 30 and 50 watts of RMS power per channel. This is not a huge corridor, just for my house and small meeting rooms. I can 't seem to find any except the vintage amps used stereo amps made in 70' where 80 's - and who knows what might take time (and they' re expensive to repair). The majority of MI appears to be mono amps and come with built-in speakers, not what I want at all. Thanks, Cezar, but the Web site are too general, also focused on "higher quality, and my research has made too many shots. I need something more specific.
