I'm sure Sowter makes an equivalent. Not sure if/how that would help. It's never been cheap to go from US to Europe, international shipping costs are insane now.
Unfortunately the UK left the European Union, so in Europe we have to pay import duties/fees from the UK like we pay from the US, with the shipping costs it makes everything really expensive.
Sowter and Carnhill transformers are costly for us now.
AVDAudio is from Russia, so outside of EU also, so we also have to pay import duties/fees.
Cinemag, Jensen, Edcor and Triad are from the US, so no really good alternatives for Europeans at the moment
