[QUOTE="Mars, post: 1115100, member: 817"] Hi All tube lovers I am building a 20 watt Single Ended amplifier on a shoestring budget. This is the specifications I want to meet or exceed: Output power: 8W*2 (superlinear connection). Frequency response: 30Hz--38KHz. Output impedance: 4,8Ω. Total harmonic distortion: ≤ 1% (1kHz). Input sensitivity: 550MV. Input impedance: 100KΩ (two input signals) Input: RCA for PC / AUX Proposed design: output tubes: 807 (triode or tetrode being considered) good bass response: primary inductance of the output transformers around 40 Henry. width of the amp: 290mm dept of the amp: 230mm (might even be less) decent power transformer decent output transformers with cathode feedback winding regular CRC power supply This design comes to mind: [ATTACH type="full"]14998[/ATTACH] [/QUOTE]
