    Tuner signal strength

    Newbie. I have a Sansui 551 that I'm working on. The FM signal strength is not displaying on the unit's meter. The AM signal strength works. My question is what AC voltage is being transferred across TO4 that the signal meter responds to? 10.7 Mhz? Thanks in advance.

    Sansui 551 Repair

    Found a 551 for $10 at a yard sale. Only the right channel works (both A and B). Tested caps and resistors, replaced blown fuses, replaced all 4 transistors - still no L channel audio. Checked voltage, checked capacitance, etc. and all checks out. What could I be missing?

    Sansui 551- probable newbie mistake

    Hi, I have been (slowly) working my way to a starter vintage setup. I purchased a 551 a few months back, I replaced the lamps and cleaned the pots but haven't touched capacitors. I'm looking forward to doing that but haven't soldered before so that should be a fun thing to learn. Here's my...

    Which Sansui to pick up?

    A few for sale locally: 2000 $165 5050 $125 551 $65 5000A ?? The 551 has some cosmetic issues on the face. 5000A has the tuner not working, currently at a local hobby tech, so no price yet. I have two quad units QR-4500 and 6500, but nothing in the 2 channel Sansui line. Would any of these...

    Sansui 551 left hand channel distortion

    Picked up a Sansui 551 recently to add to the growing collection, mainly because I have had so much service and enjoyment from my 221. However it quickly became apparent that there was a problem with the left channel, with very noticeable distortion when playing from any source, but not through...

    Sansui 551 tuner issue

    Just picked up a Sansub 551 for $20. Seller said it turned on, but no sound and tuner signal meter doesn't move. Got it home and just like they said, but plugged in my phone using the aux, and sounds good. It is very dusty inside, but looks like it has led a comfortable life. My question is: Can...

    Epicure EPI 100V or Boston Acoustics A40?

    Hey guys. Just wondering which you'd choose and why. Both are available to me for a similar price. The EPI's have new woofer surrounds, apparently. They'll be powered by a Sansui 551, which is only 16WPC.
