Default Rectifier question

Hi and sorry for the noob question.

Im looking to build an amplifier that calls for a 5U4 rectifier. A friend gave me two GZ34.
Can a GZ34 replace a 5U4 without modification to the circuit ?

Where can I find documentation on each of the tubes ?

gz34 has less max voltage and current limits. so it may work. it may also not work. read up on the datasheet and compare.

ps. most b+ schematics would state the voltage output but not the current. so you may find that voltage wise, it's okay but when you power it on, a single gz34 won't be enough. you can always use always parallel 2x gz34 to make sure you have enough current.
