    Sansui alpha 607MR

    I think the same as John, it is not a great improvement over the X-701, I like my X-701 even more than the 607 NRA and 607 DR (similar to the 607 MR), although I love all three. On the other hand, the 701 is simply majestic ...

    sansui au 717 volume knob doesnt turn

    The same thing happened to me with my 717, I solved it with a lot of patience by applying heat with a hair dryer on the metal shaft. When it got hot enough it was spinning freely, I lubricated it with deoxit loosening the screws slightly, without completely disassembling it.

    Sansui AU-517 - Sound issues (Left chnl)

    Before opening the amplifier check the rear switch "pre-power-amp", it may cause this problem. Move it repeatedly in case it has a bad contact, leave it again in the Connected position (all with the amplifier off) if the fault is resolved you can lubricate it with deoxit by opening the...

    Sansui AU-777 woofer pumping

    woofer pumping comes with increased volume, only on the left channel. With the AUX input silent, the reading on both channels is oscillating but less than 4 mv. When I turn up the volume the left channel never goes above 60 mv for higher listening levels than usual for me. However, the right...

    Sansui AU-777 woofer pumping

    Hi folks, I need help with my dear 777. When I turn it on it makes a loud bang from the woofer, I can avoid this by switching to speaker set "b" every time I turn it off. But the problem is that listening to music, when I turn up the volume from 10 o'clock the woofer starts pumping out and in...

    AU-717 Recap gone wrong? Protection mode and sparks flying...

    is the 719 that has the wrong polarity of a capacitor, in the 717 I have not seen any error. A light bulb in series helps prevent a disaster in case of a short circuit ... and as a tip I would never connect the speakers on the first test ...

    Sansui 551 thump at turn on

    I have a similar problem with my AU-777, my solution is to switch to speaker system "B" every time I turn off the amp, when I turn it on I wait about 20 seconds before switching to "A" again and start listening . In your case, you could change the loudspeakers to outputs "B" and when starting...

    Sansui AU alpha 707 DR in protection

    Hello friends, I need help for my alpha. I've looked everywhere but can't find the service manual, I've used the 707MR and X-711, but neither is exact. With the 711, despite sharing the 6160 and 6169 cards, several components differ, for example the 707 mounts 2 x 0.47 ohms resistors x 4 in the...

    The Tannoy Arden Salvage Project

    Yes, mine have very damaged wood, they were also painted (poorly painted) in the past, I would like to clean up the paint and put new natural wood veneer. I love how they sound, they have a very deep bass. Mine ride the 3828 driver. I also have some Berkeley with the HPD385A, also very good sound.

    Leestereo's Restoration and Upgrade of a Sansui AU-777A

    My 777 also does it, now I have to put the speaker switch to "B" when I turn off the amplifier, and go to "A" when I use it again, waiting about 30-40 seconds after switching on. If I do not wait for that time and change the speaker input immediately after powering on, keep doing a "pop". I...
