SB-610 P.S. diodes

[LEON WENDLER]

We have brand new selenium rectifier stacks. single
and full wave bridge. we also have on our website
"under vintage data sheets" ITT/FEDRAL catalog page
that gives all data for each model they made.
www.tech-systems-labs.com 
also this week we will be putting sarks tarzan data
sheet on all models on our website. here is link to
our ebay store for the selenium rectifiers.
