Upgrading Yaqin Tube Buffer 6J1's With GE 6AK5W Tubes (Valves)

-
I purchased my Yaqin tube buffer about 4 years ago from a Chinese seller on Ebay. I have used it as part of my system chain in different positions along that chain. Before the source and the amp, after the amp, etc...
Recently, I decided to upgrade to different and, perhaps, better tubes....... A matched pair of High Reliability 5654 GE 6AK5W *5-Star* tubes. 


These tubes are very inexpensive. The 5654's are smaller than the original 6J1 supplied with the buffer originally. It's nice to do a rotation, and I intend to purchase other tube equivalents in the future.

 I have positioned the buffer in the computer chain. So, from the computer to the buffer, then from the buffer to the amplifier. This way, it warms up the digital output from the computer before it's amplified by the AM-2800. 

 Subjectively I find the sound a little more "musical" than the 6J1 tubes. A little fuller... Overall I recommend these tubes. They come at a good price and the performance is very pleasing, so they offer very a good value.

Changing The Fabric Of Your Vintage Speakers And Changing The Surrounds

Revamping My Four (4) Large Advent Speakers Changing The Fabric On the Large Advent Speakers This year I decided to put my Advents back in full working order. I own four Original Large Advents. Two of them were in storage for over 2 years, the other two were functional in the living room. I started by cosmetics. Not only was the fabric stained and discoloured, the cats had a field day piercing little holes in them.... The result were speakers that had lost their mojo. So I decided it was time to change the old fabric on the speakers. Since I intended to restore all 4 speakers and stack them, I had to make them look good as well as making them fully functional. So, I bought fabric. I looked around and tried to find a fabric that would look good on vintage speakers. Of course this had to done without braking the bank, I could always change them again later. So, I purchased the least expensive, best looking fabric I could find. I found a good source in China . Other places asked

Akai EA-G40 Stereo Graphic Equalizer, 8 bands. Used it for a while, but my current set-up doesn't really require equalizing, also, equalizers tend to add more wiring than I like in a system... I run everything flat, what you hear is what you get... K.I.S.S (Keep it simple and stupid)!
