Default Looking for Technics SU-V75 Amp Specs

Can someone tell me the specs for an old Technics SU-V75 amplifier?

A manual would be appreciated too.

Default Similar Question...

I have a similar question but also a partial answer: I have the same Technics SU-V75, but I saw on another website that the V85 said to use 4-16 ohm speakers for it if only using the standard speakers. My question is this: I need to replace the subs in both of the enclosures in my V75, but I don't know if the info I gave above is true for the V75 as well. Any helpful comments are welcome.

BTW, I do not have the original user manual either.

Are you talking about real subwoofers such as self-powered bass units or the woofers in multiway loudspeakers? If you are replacing woofers, you need to use near identical drive units to the originals or sound quality will be non-quality. If the voice coils are intact, you can estimate the impedance of the drivers themselves by measuring their DC resistance which will be about 80% of the nominal impedance. Subwoofers are not powered with small stereo power amplifiers, particulary not those with a typical light output stage.

The SUV 85 is a substantial, 100W/8R amplifier with plenty of power at 150W down to 4R, according to published figures. Details of the SUV75, other than a web auction image, seem to be non-existent or only at a price. However, it appears to be a lightweight performer, possibly rated like my SUV50. The issue with these is that the power supply is minimal and sags to protect the single outpair transistors under load. The power supply is sometimes switched manually or auto-sensed for 4R loads which should tell you that low impedance loads can't be safely used to increase the power output. i.e. no parallel 4R speaker loads. That's what the warning is about, as any auto-sense cant distinguish <4R loads. - The warning is also on my 75W SUV50 model and you still read similar warnings on other consumer amplifiers too.

Joe Consumer just reads 8R and hooks as many pairs of 8R speakers as he can find and you get the picture, right? Yes, I fix amps and have seen it several times
