with 6x20W halogen bulbs since 2005 and not a single bulb has burn in

Philips LED 6.5W plus a Lutron Casetta Dimmer. Since then, the whole
rail has a tendency to flicker.

I know that the load has gone from 120W to 39W so the load might be too
low. Also, I undertand that dimmers don't work all the same between
ELV, forward phase, reverse phase, TRIAC. This is not common language
to me as it's hard to find the spec of this old tranformer | power
supply, the Casetta dimming mode and the preferred dimmer of thos
Philips bulbs.

Being already in mid 2018, what would you suggest, John, to solve the problem ?

Not sure there is any benefit in using 12v LEDS over mains. Dimmable 12v
LEDs are rather more expensive than mains ones too. TLC suggest if you
want to dim them you need a purpose transformer and dimmer.

I have a chain of GU10 on a dimmer which work pretty well. So might have
made more sense to convert your fittings to those - if possible.

But since you've already bought them, I'd investigate a transformer
designed for dimming LEDs.
