Selling a pair of B&K power amps. Both units are in great shape a conservative 7 to 8 out of 10 and both work as they should Both include a nice power cord. Both are quiet on start up and shut down. Shipping is not a problem at buyers expense and my packing is excellent and items are fully insured Local pick up in Twin Cities also OK.
Reference 125.2 S2 125 w/ch into 8 ohms 185 into 4 ohms Also has balanced inputs See information below Asking $375 or BO
ST 202 150 w'ch into 8 ohms and 200 into 4 ohms This one has a factory IEC socket for a detachable power cord so it must be late production as most have a fixed cord. Asking $260 or BO
The Reference 125.2 S2 (Two channel) is a high power amplifier that is designed for use in all types of audio
or audio/video systems.
The Reference 125.2 S2 amplifier utilizes high quality electronic circuitry to achieve an environment wherein
a detailed, transparent, and highly musical sound can be realized. The high quality parts complement
includes: state-of-the-art solid state devices, 1% metal film resistors, computer grade electrolytic power supply
capacitors, and a high capacity toroidal transformer. All B & K products are designed and hand assembled in
Buffalo, NY U.S.A.
The Reference 125.2 S2 operates with a class A predriver and AB MOSFET power output stages. These high
power amplifiers are capable of delivering full range while reproducing the most demanding music passages
effortlessly into the most demanding audiophile speakers.
High Current - Ability to cleanly, accurately, and reliably reproduce demanding recordings or source materials
into low impedance drivers and speaker systems.
Class A Predriver - Improves low level detail and clarity for smoother, more musical sound.
AB MOSFET Output - Provides efficient and linear power delivery, as well as protection from thermal overload.
Gold Plated Connectors - Improved sound with minimum signal loss and degradation.
Five Way Binding Posts - High quality binding posts accommodate up to 4 gauge wire.
Control Output - One 3.5mm (1/8") 10-12 VDC @ 200 mA output for controlling other amplifiers or control-
ling external systems that use a voltage trigger.
Control Input - One 3.5mm (1/8") jack that allows standby on/off with a 5-24 VDC control signal.
Toroidal Transformer - Efficient, high current, shielded transformer that supplies the amplifier with a clean
and constant supply of power, even during highly demanding source material passages.
Discrete Circuitry - Dynamically provides a full, accurate, and three dimensional reproduction of source
material.
1% Metal Film Resistors - High quality resistors used in all active circuitry to reduce noise and obtain better
sound purity.
Computer Grade Capacitors - Large capacity computer grade electrolytic capacitors for extended low fre-
quency control, increased power supply, and improved dynamics.
Balanced Inputs - Balanced inputs deliver the quietest and most accurate signal path between the preampli-
fier and amplifier.
Full Power Operation - Capability to operate at full power with a square wave input.
Differential Input Stage - A current source load assures DC stability and wide bandwidth linearity.

Some great amps here!
I'm looking forward to my next B&K. Just have to get my old SRS 2 up and running for the current owner and I'll have a B&K Ref amp that he will trade me for services rendered. -
Price drop $325 and $240
