This AIWA Microsystem power amplifier S-P22 (Japanese original version) has a BTL function. My channel uses two S-P22 BTL settings to test a number of AIWA speakers. Please take a look if you like.
I have these two components, but I have the K variants. The preamp is average but the power amp sounds pretty good. I increased the idle current from 74mA to 150mA (11mV to 22.5mV). A lot better sounding again, more musical & detail with a better low end and sound staging depth. The great thing is the cast aluminium heatsinks on the sides can handle the extra heat no problem. A great 70's mini amp.
Bonjour, je risque de me procurer le préampli, et je regardais un peu les avis ici et là.. Je tombe sur le votre et vous dites que c'est moyen. Pouvez-vous en dire un peu plus s'il vous plaît, ce serait sympa de votre part? Merci d'avance, Benjamin
@@benickumetsatulekahju484 the preamp has a fairly flat sounding and average sonic performance. It does not produce a notably detailed and involving soundstage, lacking dynamic impact and depth in reproduction. This is especially noticeable when using the internal phono stage. But note that I was comparing the performance level to the partnered P22 power amplifier. However if this preamp is to be used with mini speakers similar to what it was originally partnered with in a bookshelf setup this would not be so obvious to the ear (if one listens for these things).

これだ！43年前に購入したアンプだ！懐かしい。これで初めてLOUDNESSボタンがあるのを知りました。安かったがとても良いアンプでした。故障もなく使い続けていつの間にか処分してました。とてももったいないことをしたと後悔してます。
