Bear in mind that white LEDs generally don't look right in vintage equipment.
Who said it was vintage? They may well be yellow or amber in the end, LED white is a bit harsh.

is this the set with a push-pull output stage? If so, how will it be biased? If it's not class A, isn't there a risk that the LEDs will brighten on loud passages as the HT current increases?
A big capacitor will cure that! And if I use a pair of LEDs in series with a resistor across one the AGC would make one brighter/dimmer (perhaps)
