Like its predecessors, the 61
0T monoblock is based on a push-pull, fully balanced vacuum-tube circuit using 6550C output tubes (16 in all).

But unlike the earlier models, the 610T uses two 6550C driver tubes, each controlling a bank of eight output tubes operating in unison.

6N1P dual triodes and a 6H30 follower. XORUM required in the REF16 series.

Power output is rated at 600 + watts into 4, 8 or 16 ohm loads. Projected tube life is approximately 2000 hours.

1000 joules, with extensive film-cap bypassing of all electrolytics. In addition, interstage coupling caps are the new proprietary types first used in the REF3 preamplifier. Power supply rectification is solid-state, while a total of six regulators are used: there is a tube of the input stage, with five additional solid-state regulators.

The massive, custom output transformer is an ultra-wide-bandwidth design. And, 50% coupling of the output stage cathodes to the transformer yields both higher efficiency and better than conventional pentode or triode operation. Input is balanced only, with separate output taps for 4 - 8 -16 ohm speaker loads.

Unlike the 610T is a striking vertical design with tubes projecting above anodized top plate. Dimensions are 610 "W x 14" D x 22 "H. The" tower "chassis configuration (hence" 21T ") houses the advantages of this design allow easier, next-to-speaker installation, silent convection cooling and better weight distribution three different levels of circuit function.

At the lowest levels are the power and output transformers; on the second level are power-supply storage and regulation; and on top are the input and output tubes. A ventilated top cover with quiet Pabst fans is optional for CE compliance (which runs off a 12V DC supply jack at the back of the chassis).

Most owners want to see the tubes in their glory, and enjoy the benefits of silent convection cooling.

On the front of the 610T is a vacuum-fluorescent, multifunction display screen like that used on the REF3. The screen is addressable via front-panel knobs, or by handheld remote. A variety of useful functions can be viewed on the screen: seven levels of illumination, including off; bias measurements for each output tube; AC line voltage level; logarithmic, scalable power output (0-10, 0-30, 0-100, 0-300, 0-600 watts); and total hours of tube life accumulated.

In addition to its innovative architecture and owner-friendly functionality, the REF610T sets new sonic standards as well.

Just as the REF3 preamplifier provides remarkably clear sonic improvements over its predecessor, the REF2MKII, the improvements of the 610 over the older 600MKIII series are just as great, and of a similar quality.

Transient speed, dynamic impact, and soundness are all remarkably improved.

From massive dynamics to subtle nuance, solo voice to massed chorus, the 610T will likely never meet a commercial recording system it can not handle with aplomb and deliver with musical passion - especially when driven by its Reference partner, the Reference 3 Preamplifier.

This amplifier is the beginning of High Definition® in 1970: Audio Research.
