Pair of vintage Aegis Mullard 5-10 monobloc amplifiers. For sale a pair of fully renovated Aegis Mullard 5-10 Ultra Linear monobloc amplifiers. There is definitely an advantage to have a discrete amplifier for each stereo channel – lower crosstalk, less noise and less distortion. In listening tests I find these monoblocs perform better than the Leak Stereo 20, which whilst a similar design, shares a common power supply. An article detailing the renovation of these actual units was published in Silicon Chip, October 2014. These two units, although physically different due to chassis style and output transformer orientation, are identical electronically. Both operate in Ultra Linear format with custom wound Transcendar output transformers and follow the Mullard design precisely. Input sensitivity has been adjusted to 300mV for 10W output into 8 load so a CD player can be used directly as the input source. The current set of valves are almost new no more than 100 hours use. Output: Matched quad EL84 – JJ. Driver/Phase Splitter: Matched pair ECC83 with matched triode sections – JJ. Input: Matched pair EF86 – selected for low noise – Haltron. Rectifiers: EZ81 – JJ. The performance in all aspects is as good as or better than the Mullard specification. Please refer to the pictures, the article mentioned above and the Q&A at the end of this listing, as these form an important part of the description. These units have the provision for adding 90mm computer cooling fans, to the rear of the covers, should you wish to install them in an enclosed space. I can provide suitable fans if you are interested in this feature. Please note that these units do not currently have baseplates fitted and the internal wiring will be exposed if not mounted on a shelf or in a cabinet. As with all valve equipment these units must be treated with great respect from a safety perspective. There are high voltages and hot valves must definitely be kept away from prying fingers! I will however give whatever assistance I can to resolve any problems that should arise. I happy to arrange a demonstration of the item at a mutually convenient time. What are the output transformers you are using and why are there two different power transformers. The output transformers were wound to my specification by Transcendar in the USA. I required transformers to suit the Mullard specification for Ultra Linear configuration. Of the original output transformers one was faulty and the other was set up for Low Loading – so I replaced both with a matched pair. The power transformers are both original and of the same electrical specification. The fact that one is shrouded and the other open frame probably didn’t matter to Aegis as they were to be enclosed under the perforated covers. Have dac with fixed output of over 1 volt. Would that be fine? CD players typically have an output of 2V max and this works fine with these amps which have input gain controls. I can also adjust the input to suit any input requirement from 40mV upwards should that be necessary.
