It covers classic Mullard circuits like the and power amplifiers, which defined high fidelity in the Mullard 5 valve 10 watt high quality amplifier circuit book and whose designs are still as good as gold today/5(38).

The values of the smoothing resistor R17 given in the circuit diagram are suitable for use with the Mullard designs for two and three valve pre-amplifiers. CONSTRUCTION AND ASSEMBLY The chassis for the 10 W amplifier in which tone and volume controls are incorporated is made from three separate pieces of SWG aluminium sheet.

We bought the V main heater wiring out to a tag strip, as did we the HT winding, close to the rectifier valve as in the Mullard book. A close up of the mains and HT side of the amplifier.

Having powered it up, and tested the open circuit voltages, we plugged the EZ81 rectifier in. Upon powering up again, the rectifier glowed nicely.

This is an amplifier I built my self. The circuit design is the well known Mullard I designed the chassis on a Cad package and a friend from work got it laser cut out of stainless steel. The ends were turned from burr elm and the knobs from oak.

The transformers were supplied by VVT as a kit. Output power and distortion In view of the enormous popularity of the Mullard "" valve amplifier, it appeared that a watt output would be adequate for normal use; indeed when two such amplifiers are used as a stereo pair, the total sound output at full power can be quite astonishing using reasonably sensitive speakers.

The circuit to be described is designed to give the highest standard of sound reproduction when used in association with a suitable pre-amplifier, a high-grade pick-up head and a good-quality loudspeaker system. Two Mullard output pentodes, type EL34, rated at 25W anode dissipation, form the output stage of the circuit.

In view of the enormous popularity of the Mullard "" valve amplifier, it appeared that a watt output would be adequate for normal use; indeed when two such amplifiers are used as a stereo pair, the total sound output at full power can be quite astonishing using reasonably sensitive speakers.

In subsequent years, a succession of designs for high-quality circuits has issued from the Mullard Applications Research Laboratory, and these designs include circuits for power amplifiers and pre-amplifiers, circuits suitable for tape- recording equipment and, most recently of all, circuits for stereophonic reproduction.

A Stereo 17 watt per channel Ultralinear, push-pull Amplifier using 6CM5/EL36 output valves. The circuit design uses 6CM5/EL36 power pentodes in a push-pull Ultra-linear configuration, with a fixed - 50 volt DC grid bias.

Anode current of each o/p valve is a conservative 25 mA approx, and maximum undistorted output power is about 17 Watt/channel. Mullard Reference Manual of Transistor Circuits Mullard Ltd 1st ed Acrobat 7 Pdf Mb.

Scanned by artmisa using Canon DRC + flatbed option. A constant current source (LMHVT voltage regulator) is used to force the output stage into class-A operation. A solid state power supply is used. The tube amp kit comes with a nice steel enclosure and the power output is about 25 watts.

The amplifier circuit is very simple with minimal parts in the signal path.

It covers classic Mullard circuits like the and power amplifiers, which defined high fidelity in the 50's and whose designs are still as good as gold today.

This book has a special meaning to me because the first amplifier I ever built, as a young teen in the 60's, was a Mullard That amp was my first experience with a real hi-fi Reviews: A dual triode that can be used in place of most 12AX7 circuits.

The rugged build of this tube and reduced gain (30% less than a 12AX7) can improve headroom and give better control in high gain stages allowing users to more easily dial in sweet spots.The basic circuit is the same, but the input valves is E80F, then two EL34’s and yet two EL34’s as cathode followers to drive a pair of the even larger QB5/ “Mullard ″, “Mullard ″ or simply “Mullard 20 Watt high Quality Amplifier” as Mullard called it themselves.

It was designed by W.A. Ferguson. I know that I.
