common anode capacitor for both sections

[MaciekP]

hello,
I'm wondering if I can use one anode/B+ capacitor for two triode drivers.
This a monoblock. Driver section has the separate PSU with CLCLC filtering. I'd like to have the last cap common for both stages /drivers/. Both drivers are inductively loaded, first driver has anode choke, the second has the IT.
Is any disadvantage of using only one (100uF) cap?
Usually I was using additional resistor like 1k to separate one section and after it was additional cap dedicated for a specific driver.

Hi,

In your case I don't see any disadvantage, the choke will give you high enough interstage isolation.

Cheers,😉
