Croft Super Micro A IV phono stage valves?

[eksiil]

evening,

does anyone happen to know which of the valves in a Croft SMA IV belong in the phono stage?

much obliged

It's usually the first two, normally the first two from left to right looking from the front.

You could take out the first two and see if the line section still works, that would confirm it.

many thanks for this
