PT current rating question?

Post by Dingleberry »

Hi! I have a power transformer with following specs:
250-0-250/100mA
6,3V/3A
5V/2,1A

Will it be a little too close for maximum ratings for ac15/18w project?

AC15 PT is a 300-0-300 secondary so you are too low at 250-0-250 with the EZ81 rectifier. About 50V DC low, 275 vs. 330. With a 5AR4/GZ34 you would be much closer.

I was thinking to use other than ez81 rectifier because of the 5V tap available. It would just handle the gz34.
Probably I'll give it a try.
