Quad esl57s

Hi All
I'm going to bring the speakers down for a demo for my son
They have been fully rebuilt by Andy at A Quad Thing
How long is it best to charge them before use and can I charge them without the speakers connected to them
Cheers

They don't need particularly long Ian, 10 minutes is fine.

This can be done in isolation without the speaker leads connected.

Cheers Alan
Just didn't want to take any chances

But they will sound at their best after an hour or two in my experience.

When i had mine refurbished, the engineer at Quad said 24 hours from cold.

[wee tee cee]

Mine need at least an hour from cold

Why not let them charge up overnight?

Mine are useable after about 20 minutes, but an hour is better. It all depends on the condition and age of the speakers.

Apart from a couple of house moves and a couple of electricity blackouts, mine have been connected to the mains supply for the last 45 years.
