Vintage Tube Amp

They are the top of my heap for any EL84 upgrade.

Vintage Pioneer SX-800 Tube Stereo Receiver Amplifier 1965 Recapped 12ax7 7189a. Here is a 60s Pioneer SX-800 tube receiver. This was rebuilt in 2017. Every Suzuki capacitor and many resistors changed out. Good stuff was used!! I believe the rectifier changed to the newer style too. See pics for the work. It was our go to winter stereo, then got sidelined. It ran for hundreds of hours in the cool garage no problem. Almost always had the top off this thing it gets warm. I added tall rubber feet to let the air in. I started tube rolling, as the 12ax7 tone tubes change the sound a ton. They are now Electro Harmonix, a budget but great sounding tube. I like the sovtek lps too. There are tons out there.. Id search for new/nos 7189as. There are 2 GE and 2 with no markings. They sound great its just not a matched set. Remember these are not the 300V 7189, el84 or 6bq5s. These are the hotter 400 volt series. Music sounds crystal clear, sharp treble and good bass, but there is a tube rustle kinda sound that clears as it warms up. Not a hum just an underlying background ghost noise. When it warms up it is goes away. The first couple minutes I usually just keep the volume low and then start crankin! This is 25wpc but with good horn speakers it sounds punchy for sure, even pushing 15 altec 421s with the loudness switch on! Please inspect pics you can see the new caps and resistors top and bottom. There are newer style speaker connectors, and a new 2amp fuse holder. The pots work and arent scratchy. FM radio is sharp. This is old, and tube gear is finicky for sure, however this has been on for hours sounding great! This sounds crisp and clear, it is awesome, and the background noise is dead quiet. It is just a neat sounding unit. Writing this I dont even want to sell it, I just have a lot of stuff not being used and we have other projects to finish.. This will be boxed properly.
