The Cayin A-70T is manufactured to deliver the sound of the classic Marantz 8B. It uses four KT88s for Class A2 P.P amplification. The toroid power transformer and EI audio transformer are specially manufactured with low magnetic leakage, wide frequency response and low impedance. Two 12AX7EHs and two 12AU7EHs are used in the preamplifier. Works with KT-88, 6550, EL34, 6CA7, 6L6 or KT66 tubes. One very cool feature is the ability to switch between Ultralinear and Triode by remote control.
This piece is hand built with extreme attention to detail, including point-to-point wiring. Point-to-point was the way that amps used to be wired back in the 1950s and '60s when cost was not the primary objective. Nowadays, most everything contains circuit boards instead of this point-to-point wiring, which is much more dependable and better performing. It's one of the main reasons why these Cayin pieces sound like the classic tube gear from Marantz and McIntosh.
There are output taps for 4, 8 or 16 ohms. This allows you to fine-tune the sound that you desire. Switching is simple, and listening to the differences is a lot of fun. This amp is auto biased so there's no need to fuss with matched tubes and bias adjustments.
There is a snap-on removable cage, so that you can take it on and off with no problem. Keep it on if you're worried about protecting your tubes, or take it off to show what real, heavy-duty, classic tube gear looks like. Turn off the lights and watch 'em glow.
