Hello to all. I just got an AU-111 off of the auction site and it has lived a hard life. Bought it from a fellow audiokarma member and he told me that a friend of his bought this off of the auction site as well…from an overseas seller. Well this unscrupulous seller decided to remove the...

What advantages and effect on sound does adding preamp tubes have? I have had multiple pieces of vintage gear from various manufacturers with a variety of preamp tubes. I’ve had a Sansui 1000a, Scott 340b, and Fisher x-101-d with 2 12ax7 preamp tubes, a Sansui AU-70 with 3 12ax7’s, and a...

I’m new to the forum and I’m really enjoying my journey into vintage stereos. I have a Sansui 1000a tube receiver that I am currently in the process of restoring. In the meantime I am running my speakers with a Yamaha htr-5630 receiver, 70 watts per channel. I have a set of original large...

Hello to all. I am new to the forum and I recently bought a Sansui 1000a off of eBay. The seller said he could not get the unit to power up. Upon receiving said receiver I found that the power cord was cut. I was happy to see this because it prevented any damage occurring due to faulty caps...
