Premier Twelve & Twelve-XS Vacuum Tube Power Amplifier
Introduced in October 1993, Twelve XS in June 1995
The Premier Twelve is a mono-block tube power amplifier, in effect a smaller, lower powered version of the Premier Eight. It uses two pair of 6550s to produce 140 watts. It is similar in size and circuit to the stereo Premier Eleven. The Twelve-XS is a Twelve with the output stage configured to use a pair of EL34s operated as triodes to produce about 60 watts.
The Premier Twelve used only the finest component parts in all stages including the power supply. The power supply used only polypropylene and "cjd" polystyrene capacitors as opposed to the traditional deployment of electrolytics. The main storage reservoir used polypropylene capacitors with polystyrene shunts.
