The SFS-80 is Sonic Frontiers' top of the line tube stereo amplifier. A rather hefty unit, it is built like a tank and is likely to last like one. From its thick brushed stainless steel chassis and transformer top covers, State of the Art passive parts quality (MIT MultiCap, Vishay, Holco, Cardas and Edison-Price parts), 66 lbs weight, and massive transformers, one gets the accumulated impression that this company builds serious audio equipment of industrial grade quality.
An 80 watt vacuum tube stereo amplifier featuring a regulated pentode output stage, the SFS-80 is said to also utilize a multi-secondary output transformer. Twin 6DJ8 tubes comprise the input and driver stage. A front panel bias meter is provided along with externally mounted adjustment controls. This user friendly feature along with the instructions in the owner manual allows even an amateur to bias this amp. I wish more tube amp manufacturers offered this feature. I believe this will attract new tube amp ownership.
An open chassis design with metal cage as a safety implement, the SFS-80 is factory supplied with matched KT99's or KT88's depending upon the version. One may also use 6550/6550A, KT90 types, or EL34/6CA7 though the latter will reduce the available output by about 50% to 40 watts.
The amp comes with a detachable power cord, a boon for those who prefer to upgrade this later on.
