The above is the case of this small vintage tube radio power supply, the Ameco PS-1, that I bought last summer from US on a well known site for on-line auctions.
I put hereafter a small collection of images of the Ameco PS-1, together with its very simple schematic diagram. It can provide 6.3 VAC, 2A for tube heaters and a rectified 125VDC, 25 mA for plates (often named as the B+ voltage).
I would like very much to use the Ameco as (a part of) the power supply section of a future homebrewed tube radio, most likely another simple regenerative receiver. I could also add in the receiver some better filtering on B+ and a rectifier - followed by a three terminal voltage regulator (LM7806 or similar) - for the heaters voltage and leave the Ameco PS-1 as it is. Of course, here in Italy it will require a step down transformer from 230 V of AC mains to the required 117 VAC that are used in the US, but this would not be a big problem, given the limited power to be delivered.
That's all for now, with my best wishes to all for a great year 2015.
