Reply with quote  Mark this post and the followings unread

Hi,

Can anyone help me source a suitable transformer for the MFOS Adjustable LM317/LM337 Supply please? I've been catching up on previous threads about this, but still need some definitive advice. I'll be running this at +/-15v

I'm UK-based, and usually order from CPC to avoid heavy Fedex costs

Thank you!

I haven't seen any previous threads but the reason the transformer isn't specified is that making a mains supply like this is not a beginners project.
The first four paragraphs on the MFOS site spell this out quite clearly.
On the other hand, if you know how to wire it up, this one should be suitable :- http://cpc.farnell.com/camdenboss/ctfc50-15/transformer-50va-2x-15v/dp/TF01351?Ntt=TF01351
This will be able to supply just over 1A continuous per rail max. - slightly more short-term.
