I am selling this outstanding Leben CS-300XS. Rarely seen for sale on Audiogon. Read all the wonderful reviews. The Sovtek tubes have been replaced. The EL84 tubes are NOS Philips Holland, and the driver tubes are Russian re-issue Mullard brand. They have maybe a few hundred hours on them now. I turn it on only sparingly. It is in great shape, and will be shipped in the original box. This is the US 120V version. Buyer must pay for insurance. This amp was paired with Devore Gibbon 8"s and sound wonderful.
