Many years ago I met Jan Lodström a Swedish designer of valve amplifiers.
He had designed a standard valve pre amplifier called the REMUS, which was an amplifier one could describe as “blameless”.
I removed the power supply from the original design, (chassis) and designed one with a fully smoothed 250v supply, and a fully stabilized, 6.3v heater supply.
For those who are interested, here is the full article, http://ift.tt/1MKy119
The physical design is mine, a good friend milled the chassis from a solid piece of aluminium, he also made the channel knob, volume control knob, and brass push buttons.
The valve covers where made by a friend in the UK, and the handles where made by a “blacksmith” in Tyresö.
My intention was to produce a few units for sale to enthusiasts, and there was to be a valve power amplifier to compliment it, however fate intervened and my car was stolen together with the amp in the boot, unfortunately my car was never recovered.
Here is the only image I have of the pre amplifier, which I found, having thought it was lost until some weeks ago.
As the image is reproduced from a photograph the quality is not so great.
How do your amplifiers look, there must be a few HiFi nuts on the forum?
