Bridge Rectifier for the heater 300b tube amp

Hi Looking to upgrade 4 bridge rectifiers on the heater for the 300b amp. Should i custom 4 diodes to make a bridge. If so any recommendation on which diode i should use? Any members can advise on this. Thanks!

I had 25amp ones but after 2 years they cracked. Make sure you mount them on the chassis with paste for some heat sinking. http://www.mouser.com/Semiconductors/Discrete-Semiconductors/Diodes-Rectifiers/Bridge-Rectifiers/_/N-ax1mf?P=1yzxhyxZ1yuo9ua Cheers George

Besides the fact that a bridge is more convenient and easy to install ( less of a hassle) a custom bridge will give you more reliability and better performance? If i custom my own bridge for the heater, do you recommend fred, hexfred or Schottky? Will be for the 300b heater, the unit came with 4 bridges Rs802 (8amp 100v). Please advise??
