I no longer own this amplifier as I sold it around Oct-2001. It's a great amp but I prefer my CJ Premier 11a amp.
Audio Research VT100MKII vacuum tube power amplifier. This is no low budget new comer to the world of audiophile class vacuum tube audio gear. ARC has been around for some 30-years I replaced all 16 tubes inside this amp and will describe the process including biasing the power tubes and the driver tubes. It's a bit involved especially if replacing the driver tubes. Some knowledge of electronics and the ability to read schematic diagrams is essential. Click the photo to move to the next page.
