Crimson Elektrik 530 monoblocks for sale

[PreferValves]

I have a pair of these great power amps for sale.
I bought them second hand many years ago, re-sprayed the case lids and put in pure silver co-ax for the inputs (The Maplin stuff).
They worked brilliantly for many years, but one of them now has a DC offset of around 2-3V. They both still work, but the one with the offset gets rather warm and could damage the speaker it's connected to. I can cope with most electronics, but alas not the transistor. I've tried the preset on the board, but to no avail.
The output sockets (just for 4mm plugs, they are not binding posts) are hanging out loose.

I'm hoping someone here might want to buy and fix them, as I don't think they are safe enough for eb*y. I would prefer any buyer to collect them in person so that they can inspect them. I am in central London, UK.

I've just sent you a PM about these.

The Crimsons have now been sold.
Thank you all very much.

The preset is for output bias adjustment.
I think it is done while monitoring the quality of the output signal, rather than measuring a Vre or similar.
