Default Re: Toroids as O/P trannies

I've used mains transformers as emergency p-p output transformers on one or two occasions, and they work, but be aware that the construction of these transformers will probably give you a restricted frequency response, so I don't think that hi-fi applications are in order! However, for a replacement in a set working on the AM bands where treble is restricted, you would probably find such a replacement adequate.

Even with single ended stages, you could probably get away using a mains transformer in a stage using a battery valve or a small mains output valve - I've experimented with such and found no problem with core saturation.
