Today my board has come in and this is my first build.
I want to give a local (non audio)transformer maker the ideal specs for a power transformer for the Tubelab SE with 300b at 390v. I use 5k 8Ohm opt and our grid is 220volt.
I am at this point.
Pimary 220v
Secondary
2x 390 v at 175ma center tapped (390-0-390)
2x 6.3 volt 5a (6.3-0-6.3)
1x 5 volt 3a (5-0-5)
Triple windings-chassis mount- wire leads 15 cm
Is this about right or did i leave something out? And does the transformer maker need to know other things about the specs, because audio is its intended use?
Already many thanks and happy building.
