Audio Research LS2B Hybrid Tube Preamp

Description

Audio Research LS2B tube/solid state hybrid preamp in excellent condition. It's fully working and sounds great...never harsh.
It is in very clean cosmetic condition with very minor blemishes from normal use.
Low hrs 6922 Electro Harmonix installed 11/19 (Audio Research recommended). Unit has been typically turned Off when not in use.
Volume
is a rotary, metal-film control with 41 steps and it has a nice feel.
The 9db Gain Reduction mod has been done as per attached photo.  This is needed with non-ARC amps or Hi Gain CD. Otherwise the Volume control ramps up quickly and limits range of control. Use with an ARC amp still works fine.
The B units have a Balanced XLR output for all inputs including RCA and a Balanced XLR Direct input
for the cleanest signal path (
selected by the front panel paddle switch).
The original unwieldy 8' power cord has been replaced. It was the only thing I didn't like about this preamp in 25 years of ownership and enjoyment. This model does not have an IEC power socket so I had an audiophile tech install a 5.5' power cord as shown.  It fits through the original chassis hole without modification.  It is 16 gauge with individually shielded, teflon insulated pure copper conductors.  It made a nice upgrade.  The original cord is included if you wish to restore.
Original box and packing included.  Tube removed and packed in foam for shipping
