Default Help Required to Find a Transformer

Hi,

I am looking for a transformer for a simple 2 valve headphone amp. The spec is 2 x 150V 35mA and 1 x 6.3V 3A secondaries. The Hammond 269BX and 369BX from Mouser are the closest I can find and are 45 and 64 respectively. Three questions :

1 Are Hammond transformers the best value-for-money ?
2 Is it worth paying the extra for the 369BX for the Faraday copper primary shield ?
3 The 6.3V secondary is 2A and I need 3A. Do I need 3A for two heaters in parallel or will 2A be OK ?

Thanks

Mark
