Audio Research VT 100 MKIII


How does this amp compared to ARC amps that followed? Is the amp worth much on the used market? How was it's reliability?

"Is the amp worth much on the used market? How was it's reliability?"

I've seen several VT-100's list here on AG at pretty reasonable prices. You may want to consider a Mk1 or 2. I'm not a big fan of the 6h30's myself, and you may find that you like the older version better.

I understand the MKIII is a LOT simpler to bias, anyone have how the MKIII gets biased?"

If I remember correctly, the Vt-100 has one bias adjuster for each channel. That means you set the bias for all the tubes in a channel at the same time. You make 2 bias adjustments instead of 8.
