So, any recommendations for any different transformers, ideally in the
Screwfix range, that you have successfully used with a 20W load?
Screwfix do 5 or 6 different ones that all say "20-60W" so maybe
another type may be better that the ones I have. They don't do any that
go down to, say, 10W minimum, which would be more ideal.

Dunno about screwfix, but a proper transformer will work with a small load
- although the voltage may be a bit high. *But TLC list both those and
electronic ones which apparently have no minimum load.

Thanks Dave, might give TLC a go - haven't bought from them for a while.
Unfortunately the best looking ones there are out of stock but will have a
look in a few days time.

I did think about just using a traditional toroidal transformer from Maplin
or similar - they did a suitable potted one, but that's now discontinued.
They still do some bare 30VA ones which might be OK if I'm desperate - they
would certainly work with my small load.

Simon.


Why do you think the problem is too small a load? If it says it works
ok with 20w, it should, or something's faulty.

You can also use a toroidal or EI transformer, the latter are common
in any electronic parts catalogue. But with these you should use a
lamp wattage close to the max transformer rating, or the voltage will
rise and the lamps not last well
