Tubelab SSE for 220-240v operation

[JedPhillips]

Hi there -- I'm building an SSE to work on UK voltage (nominally 230v). Apart from making sure I get the correct power transformer (thinking the Hammond 374BX), are there any additional modifications I need to make? Does the 50 vs. 60Hz have any influence, for example? Or is the output from the transformer identical regardless of the input voltage?

Thanks!

Different voltages are possible on the primary side.
This also changes the voltages at the output a little.
The behavior can also be used to make adjustments.
50 vs. 60 Hz has no influence.

Are you sure about that? I read that the EU harmonisation of mains supplies stipulated 235VAC with 5% leeway, and the UK supplies of 245VAC just fall into line, so I would expect at least 240V in the UK.
