One of the dullest looking '70s stereo receivers I ever owned. Mine is the model SA-5370K, with the dark brownish front panel. I no more recall whether the letter K stands for the face and chassis color, or the european market model. This receiver's face is as close to ugly as could be.

Never mind the book's cover. With its 2x48W to 8 ohm, the SA-5370 is almost a true powerhouse of the '70s. And the amp sounds very pleasant, warm. The Technics appears giving slightly stronger bass sound than that of for instance the Marantz and Pioneer stereo receivers and amps I experienced, and I kind of like listening with the SA-5370 bass set at 11 o'clock, rather than my usual noon. In highs, SA-5370 possibly is quite not as vivid as the best '70s amps I experienced. Anyway, in all this amp sounds good.

The amp drives 4 ohm speakers effortlessly. Turn up the volume, and the amp does just fine. One may almost rock the house, with this ugly little beast. Just don't switch loudness on, which is the case with most amps and receivers. This Technics loudness, though, is not of the worst I ever heard.

SA-5370 offers subsonic and high filters, both. The amp section has no mono switch. Adding to Phono and AUX inputs, there are connections for two tape recorders [cassette, reel-to-reel]. So being, SA-5370 has enough line inputs, for the most usual needs.

All the controls and switches feel sturdy enough, but volume control knob could be larger in size, preferably the same size as the tuning knob. All the switches are just as robust as they were, in '70s proper hifi gear. I guess we all know these flimsy micro switches which emerged along the '80s, with their constant contact issues: take for instance the SU-V670 and alikes, from Technics, too. I would not know if this SA-5370 I recently bought ever was maintained, yet the 40-year-old receiver has no contact issues whatsoever.

Speaker lines properly are with relays, but the speaker connections are annoingly small in size, and old-fashionedly meant for apiko fork connectors. With just peeled cable ends, one must watch out for loose hair. These screw-type connectors were used by especially Japanese hifi manufacturers, still in the '80s.

The SA-5370 FM tuner section appears average, yet works fine enough, for local reception. I could try the FM tuner, using an unbalanced 240...300 ohm wire-dipole only. I have outdoor FM yagi antennas with 5 and 8 elements alright, but the 75 ohm antenna connector on SA-5370 is weird enough, short-circuiting the antenna cable.

Technics SA-5370K, dull looking yet good sounding, and in overall features and functions a decent amp. In second hand market, I reckon this receiver somewhat is undervalued even though SA-5370 deliveres power, as well as sound, equal to for instance one of eBay's most wanted, the Pioneer SX-780/790.

Looking for help

I recovered a SA-5370 looking inside and out in prime condition.
Looks as if the receiving part is OK but no sound.
Happy to find schematics here...
But now where to look first...

If the unit has a speaker

If the unit has a speaker relay,check if the relay in engaging.You should hear a click about 5 seconds after power up,if there is a speaker relay.If there is a relay and it's not engaging check for any fuses that may be bad.Then check the DC of both power amps.You can check that at the speaker relay contacts.If there is DC,you will need to repair the bad channel power amp.

I recently inherited a Technics SA-5370 in very good condition & functions perfectly. I really have no use for it and was considering selling it but cannot find any websites that have it for sell to get an idea of it's value. Any ideas on the average value of this unit? All suggestions would be greatly appreciated.
