| The circuit is simple, yet is capable of excellent performance. I designed it specifically for use as an amplifier for the digital sound card in my computer. Audio input can be from any two-channel line level device such as a television, CD player, or VCR. It is of the tube type, using only 5 tubes total with no more than about 45 Watts power consumption from the outlet. It uses 3 types of tube 1 5Y3 GT vacuum rectifier, 2 6SF5 GT high-mu triodes, and 2 6K6 power beam amplifiers. These are all full-size octal type tubes which are commonly available today for between $3-5 each. |

| Plaese Use 0.1mf ok | ||
| can u explain how the tube connected???? i like your project...i need to understand more.. can u explain to me.... | ||
| Transformer T1 is specified as having two 6.3V secondaries, but shouldn't the secondary connected to the 5Y3 rectifier be 5 volts? Also, "C8" is shown in two places and has a value of 15uF@400V. 15uF seems like an extraordinarily high value for these capacitors, which are sometimes used for line-noise suppression (and not a recommended method, because they usually just add more noise contamination to the ground). More usual values for these capacitors are 0.001uF high-voltage (1KV) ceramic disc types, but I recommend that you leave them out if there is no line noise problem to begin with. Also, put a suitable fuse before S1 for fire protection, notate the schematic so that the right side of the plug is "N" for neutral, and include a three-prong plug with a earth safety ground tied to the chassis. The combination of no ground along with the presence of either or both C8s may cause an immediate lethal shock hazard. | ||
| if I can't find the T1 you specified, can i use two transformers for the primary. IE: 0ne 117V Primary, 350VCT Secondary and, One 117V Primary, 6.3V Secondary. | ||
| id like to built this amp but the problem is that i cant find T1 could u pls tell the part number or model or anything about it 10x | ||
| i have made this amplifier sounds well but there is enormous buzzing when you increase the treble pot. the output is 2X4 watts but is a good power for a medium room | ||
| Hi, you fogotten to writ what are the output power. Bye | ||
| I would like to know if a quad diode full-wave rectifier with capacitance multiplier circuit can be an adequate alternative to the 5Y3 GT vacuum tube rectifier. A very nice and simple circuit btw, I'd love to build it as soon as I get the materials! | ||
