Note that the 4 uf is a "typical operation" value not a maximum. In the RCA
receiving tube manual (1950) they have typical capacitance at 10 uF, but then
show a circuit for a 25W 6L6 AB1 amp which has a 5U4-G followed by 40 uF.
As was noted, the real maximum limit is the instantaneous current, which
for this tube is around 2.3 amps, so the real limit depends on the plate-to-plate
impedance through the transformer.

Depends on how much current you're pulling, and how much ripple you can stand. Why use a 5U4G anyway? The 5U4GB has a much higher Isurge rating.
Re: Re: 5u4g input capacitor
Thanks for the enlightening replies.
I will be using it on a direct coupled 5842-2a3 SE amp. I was thinking that the ST bottle of the 5u4g will look good with the 2a3.
