Info on transformer

[mlx]

Was hunting around for a trafo to feed a generic rectifier for a B4 build and came across this - http://goo.gl/4oG17S. I was wondering if anyone has experience of this make and model and whether, in this instance, low price and quality can go hand in hand. Otherwise any recommendations? Thanks

I don't know the specific model, but I expect it would work fine.

You could also use a smaller one - 10 or 15VA would be just as good. They are only a pound or so cheaper, but are rather smaller, which saves space in the case.

THese are good little transformers 2 X 15v or 2 X 18V and 25VA is what I use and I have a big torroidal in before this and this sound every bit as good
You can get these from RS components

Here is a one in a little phono stage build

Thank you all very much for your kind assistance and advice.

Must say the Talema-Nuvotem looks pretty neat. Do they come supplied with the PCB for mounting? Very nice phonostage build too.

No unfortunately they dont come with a PCB we had a group buy on them a while back
If you buy one of these from Audio wind you do get the PCB with it but they are a bit pricey I cant find them now but I think he sells the PCB for £6 each?. BTW these transformers are very good as well

Is there any benefit to those encapsulated transformers aside from the fact they are PCB mount? Do they offer better performance than the open toroidal types?

I would expect them them to be mechanically quieter, as they are glued into a solid lump.

Glue? I've been using solder...I knew I was doing something wrong And where do you buy solid lumps?

Alan, thanks for the link. Think I'll file that for future reference - I remember reading on one of the B4 build threads where PigletsDad mentioned that B4 is pretty tolerant of trafo quality. Seems a shame therefore to use such a good transformer where its potential will be untapped. I do find it strange though that pcb trafos are not sold with a pcb (or as an add on by the original manufacturer). Seems such a natural pairing.
