Hello,

This valve is stated under "Base" as having a European four pin base.  However, the illustrations and base pinout diagram show a UX type base.  This valve is a direct equivalent of the UX245 so the UX type base is correct.  I have not been able to determine whether this type was made with the European 4 pin base.  Also listed on Radiomuseum.org is an F203A however, the valve in the photos is marked F203.  I think that these photos should be transferred to the F203 page.

Regards,

Stuart Irwin

Hello Stuart,

I have corrected the base type, as well I moved the photos from the F203A page to the F203 page. There is no information available about the differences between the F203 and the F203A, but I can hardly imagine there are big differences.

Best Regards, Jacob
