5U4 Rectifier. Maximum filter cap value?
I''m putting together a tube rectified power supply (for a power amp) which uses a 5U4G rectifier. The GE 5U4 data sheet lists (under typical operating characteristics) an input filter capacitor of 40 mfd. They don''t list a maximum value. Mainly my question is, can a larger value cap be used in this location?

Safety Tips For Working On Tube Amplifiers
Electrolytic (and other type) filter capacitors can hold lethal charges - be sure to discharge them before working on an amplifier. This can be done by shorting the "+" side to the "-" side, or the "+" side to the chassis (unless the cap is in a negative voltage supply, like the bias supply, where you must short the "-" side to the chassis), using a wire or a screwdriver.

For any position where a capacitor is connected across the mains or is subjected to similar AC voltages, Class X2 suppresser capacitors must be used. If the failure of the capacitor could put the user in danger (such as a blocking capacitor in line with an aerial, earth or gram socket on an AC/DC set) a Class Y suppresser must be used to comply with electrical safety regulations.
What determines your B+ filter capacitor size?
Hello, does anyone know what determines the different sizes of filter capacitors in an amp? Im talking about the filter caps right after the bridge rectifier. My rivera has 2 330uf caps in series for a 165uf total, my framus had 2 220uf caps for 110uf and a 1959 marshall seems to have 2 dual run 50/50 caps in series for 50uf total I think, is

6 FAQs about [Filter capacitor safety valve]
What is a safety capacitor?
Safety capacitors are also called EMI / RFI suppression capacitors, AC line filter safety capacitors, or X- and Y-rated capacitors. X and Y capacitors not only keep radio frequency noise generated by the device local to that device, but also protect the device from mains noise and high voltage surges.
What is a line filter safety capacitor?
Line filter safety capacitors can improve the reliability, safety and performance (sound) of your vintage tube radio.
What voltage is a safety capacitor?
With a working voltage of 400 VAC in line-to-line (Class X)and 250 VAC in line-to-ground (Class Y) applications, these safety capacitors meet the impulse test criteria outlined in IEC Standard 60384. Meeting subclass X1 and Y1 requirements, these devices are certifi ed to withstand impulses up to 4 KV (X1) and 8 KV (Y1) respectively.
What is an AC line filter capacitor?
