Description
For sale is a highly sought-after, audiophile-grade Graaf GM20 tube power amplifier, utilizing the prestigious OTL (Output Transformerless) topology. Designed by the legendary Italian engineer Giovanni Mariani, this amplifier represents the absolute pinnacle of valve transparency and musicality.
Key Features & Highlights:
OTL Topology (Output Transformerless): By eliminating output transformers, the tubes drive the speakers directly. This results in breathtaking speed, unmatched transparency, micro-dynamics, and a lifelike realism that standard tube amplifiers simply cannot match.Pure Class A Operation: Runs fully in Class A, delivering stunningly liquid midrange, rich textures, and silky-smooth highs.
Power Output:
2 x 20W in stereo mode, or can be bridged as a mono-block to deliver 1 x 65W. It is surprisingly stable and offers excellent control (best paired with medium-to-high sensitivity speakers, 90dB+ recommended).Robust Tube Complement: Utilizes the legendary 6C33C Russian triodes, famous for their military-grade reliability and massive current delivery capability.
Italian Design:
A striking aesthetic featuring an exposed tube layout and a heavy, resonance-free chassis that serves as the centerpiece of any high-end audio system.Condition:Cosmetic & Technical Condition: 10/10 (Mint condition, meticulously cared for in a smoke-free, pet-free environment).Maintenance: Recently fully inspected and biased by a professional technician.Tubes: All tubes are in excellent health with very low hours of use. The amplifier runs perfectly quiet with zero hum or noise.
Technical Specifications:Power Output: 20W + 20W RMS (Stereo) / 65W (Mono).
Output Impedance: 8 to 16 OhmsTube Complement: 2 x 6C33C, 4 x 6922 (ECC88)Weight: Approx. 22 kg (Heavy, high-quality build).
**********************************************************************************
I prefere "face to face deal", local pick up, demo listening in my apartment and cash payment.
Due to the weight, I highly prefer local pickup.
For serious buyers, collection/pickup is possible within a 250km radius of Ljubljana, Slovenia.
I have original box for Graaf GM20, shipping is possible to EU. Will pack very very safe!
Buy with confidence, check my Audio Markt ratings.
Feedback here on AM is very important to me, so I always do my best for every buyer.
Live video call is possible too.
