Trafo for dumbleator

[sergio]

Hi all , Where can I find a trafo to use for a D-lator in rack unit?
Thanks

[JD0x0]

someone mentioned using a weber reverb transformer. Someone else will chime in as i'm not certain on the exact required specs for a d-lator

Check out my thread. We discuss all that.

I have this one for you. They are custom made for me.
Prim: 115-0-115-0 Bridge for 230V
Sec: 135V@60mA; 12V@300mA; 6,3V@1,5A

H= 52 mm W= 65 mm D=40mm

Prim: 115-0-115-0 Bridge for 230V
Sec: 135V@60mA; 12V@300mA; 6,3V@1,5A

H= 52 mm W= 65 mm D=40mm

If you don't mine me asking, what is their cost

You can also use 1n242 from Amplimo: http://www.amplimo.nl/index.php?page=sh ... 34&lang=en

I build 4 units with it. They all work fine.

Sergio, what is the full Italian word for 'transformer'?

Prim: 115-0-115-0 Bridge for 230V
Sec: 135V@60mA; 12V@300mA; 6,3V@1,5A

H= 52 mm W= 65 mm D=40mm

Presumably EI laminations rather than toroidal since it's rectangular, or is it encapsulated?

Is the secondary 135-0-135?

For jaysg

Transformer = Trasformatore

OK this may explain why transformer or the commonly accepted English abbreviation XFRM has changed to TRAFO (German translation).

With all respect to Nikola Tesla, I'll continue to use XFMR. for the same reason why I use eight instead of ocho.
