Hi to all.
I m on gathering the parts for TubeLab SE but icant find the FREDS for negative voltage for the bias.As the title says what alternative diodes can i use and if it is possible to tell me where i can find them.I m from Greece and i ve searched in a local electronic store but i didnt find anything.
thank you.

You want the Fairchild ISL9R8120P2 solid state rectifier diodes.
What brands of rectifiers are available in your area?

Glad you found some. Keep in mind there is a high incidence of failure reports over recent batches of the IXYS parts. The Fairchild diodes appear to be much more rugged, and if you have the opportunity I'd recommend you use them instead. See some comments here:
