Stereo Tube Amplifier 2A3 45

Amazing Warm Sound - 100% hand built


Beautiful, 100% hand built stereo, singled-ended all tube power amplifier using 45/2A3, 6SL7 and 5Y3 tubes. This amplifier layout has been carefully designed using a combination of Vintage, and high quality components. These high quality components are brand new and consist of Triad filter choke, Hammond Filament transformers, Heyboer output transformers, Illinois electrolytic capacitors, poly capacitors, carbon resistors, gold-plated RCA jacks, speaker jacks, top grade ceramic tube sockets, IEC connector and power switch. Coupling capacitors are poly coupling caps. Illinois electrolytic capacitors are used in the cathode section and Cornell-Dubilier electrolytic capacitors are used in the power supply section. Vintage Marantz dual stereo volume control was used and in the input stage, gold plated shielded wire was used. All components are perfectly matched left to right for proper channel balance. This amplifier was designed on a garolite board, with all handwired, point to point circuitry using less wire to prevent hum and all grounds are in the correct places. This design allows this amp to run continuously, with extreme quiet operation. This amplifier has built in volume control and can be used with or without a preamp. You can connect any fixed or variable source output directly to this amplifier. You can use the audio out from an iPod, CD, DVD, MP3, Computer, TV, XM or SIRUS to the input connection of this amp. Amplifier was designed utilizing four tubes, one 6SL7 (Input) can be substituted with 5691 and two 45 (Output) can be substituted with 2A3 and 1-5Y3 (Rectifier) can be substituted with 5U4,GR34 or 5AR4. This amplifier features a single pair of inputs, volume control, power switch, power indicator, right/left speaker terminals (4 Ohms) and circuit protection. You will be amazed at the bass sound of such a small amplifier. Amp works great into any 4 and 8 ohms speakers.
