Title: SE 30W AUDIO TRANSFORMER
Post by: Colas LeGrippa on October 18, 2011, 01:48:04 pm

Hi,

in my next build I need  a SE tranny for 2 X 6L6. The HAMMOND 125GSE would be great but I'd prefer a transformers with covers. Any suggestion ?

Hammond's 1627 series come with covers. Just forget the UL tap and you're set.

Some people have reported excellent results with the Triode 30SE OT (sourced from Magnetic Components).

Doberman sometimes offer a smaller OT, built by Heyboer, which could also be OK with 6L6s.

You can also consider one of the many "audiophile" OTs, for instance the UBT range from One Electron

As you live in Italy Québec, shipping can be a very expensive proposition if you import a large OT from the USA.

often the grass in the neighbor's yard looks greener on our

I can ensure you that Italy is a very nice place with history and culture as well as magnificent landscapes

but even Canada is a land with magnificent forests that here are not more by centuries and also you have history and culture  :smiley:

in this moment of difficulties I think many people would go away from where they are, hoping in a new chanche, don't think here we haven't problems, on the contrary .......
