FS: Graaf GM20 OTL (output transformerless) tube amplifier, 20 WPC of pure triode bliss. class-A circlotron topology, balanced and single-ended inputs. I have used this amp with Quad ESL 57 and 15 ohm LS3/5a and they're a match made in heaven. The GM20 is a cult item in Asia and I can see why, few come up for sale and many have found their way to HK and Japan - dont let this one slip away! Manufactred in Modena Italy, home of Ferrari and painted in same black auto lacquer. The construction is first rate with a huge PS (generous capacitor bank and toroidal xmfr). The condition is excellent save for a very small scratch on the front lower left hand corner of the chassis, not noticeable from two feet away. the power tubes and small signal tubes have lots of life left. Not pictured but included is the cage, also finished in gloss black. I have the complete documentation, including manual, CD ROM of biasing procedures, double factory boxes etc. +3% for paypal. Approx weight is 65# For speedier replies, contact me at: puroagave@yahoo.com
