i think the best bet with ceriatone is to source your own transformers, not a knock on their iron, but the difference in shipping cost is about 100 bucks if you skip their transformers... it also gives you the freedom to pick whatever transformers you like. For this type of amp I'd probably skip the mercury mags and go for heyboer or classictone.
