The closest (unexpensive but new and available in Germany) which I could find is
- 2 of Gerth EAN 2050001920652; 38 mm x 32 mm x 45 mm; 5.6VA; 2x30V (=120V); @5,50 EUR each = 11 EUR ; Safety-Transformer, IEC 61558-1 and 2-6; protection index IP 00; prepared for class I / II equipment; vacuum potted; max. admissible ambient temp. 70°C; 2 chamber safety-bobbin; test voltage 4.000 V ac; non short-circuit-proof; approval mark: VDE, ENEC 10
Looks good if it fits in the case.
otherwise the smaller "brother" (3 to 4 mm smaller in each dimension)
- 2 of Gerth EAN 2050001920355 ; 34 mm x 29 mm x 41 mm; 3.6VA (could be at the edge) @4,40 EUR each =8,80 EUR
Maybe you find something more appropriate or an option with a better availability in your country.
