Super clean sounding amp, its small but built with quality materials inside and considering its only 45wpc it really delivers

Great presence and punch. Lovely amp that's built like a tank and wonderful connectivity.

Technics SU V470

Just picked up one of these as part of a package including SL P477 CD player, ST G70l Tuner , RS B665 tape deck and bookshelf speakers, all for under $100
Its a lovely unit - not as polished a perfomer as my SUV10X but sounds similar and has the same smooth warmth that has made me a fan of Technics gear for 30 years.

Given the number of people getting rid of late 1980`s and early 1990`s gear to "upgrade" to 5.1 cinema all in a box systems, these are going for a song.
Pick them up now before people realize how good they actually sound compared to "modern" gear.

Just a question, please.

Dear Jdoconty
I have just bought a SU-V470 second hand but it doesn't work.
I mean I connected a tuner, 2 speakers and no sound, not even the usual zzzzzzzz noise of an amplifier on with no signal in, came out. Any suggestion? I think I connected everything ok. I even changed the speakers but to no improvement.
Thanks for a reply
Ciao

SU-V470 Technics no audio out

Ciao Maurizio,

2 consigli:

a) con i pulsanti degli speaker attivi subito dopo l'accensione ascolta se senti il classico "click" del relais anti-bump dopo qualche secondo dall'accensione. Se non lo senti probabilmente l'apparato è in protezione perchè rileva una DC sull'uscita di uno dei 2 finali. A questo punto occorre una riparazione presso un'assistenza. Prova comunque a mettere le casse su entrambi i gruppi (A e B) tenendo sempre attivi i pulsanti di selezione dei gruppi casse in uscita prima di decretare il guasto.

b) prova ad inserire una cuffia e verifica che si senta qualcosa (non ho lo schema di questo apparato ma spesso la presa cuffia non viene derivata sull'uscita dei finali ma ha un suo circuito indipendente e quindi, se il preamplificatore funziona, dovresti sentire il programma audio in ingresso).

Saluti
