FS: Neurochrome 686 or PX for Lyngdorf

[Mr.Ian]

Being toying with simplifying my set up for a while, loss of job and the need to get a newer car has brought it to a head.

First to go is my beloved Neurochrome 686, best power amp I have/will ever own £2200 collected from North Nottinghamshire close to M1 J28
Price is firm

The amp was professionally built by AD Audio and has the slow start and speaker protection circuits - note many of the units offer on ebay dont appear to have these.

see AD Audios orginal sale post below:

Note: the unit has been in my rack since I bought it, the only mod being the addition of an earth socket to the rear. I use it for grounding my sub woofers that run in balanced mode. I takes the form of a discrete, green, 4mm socket that is isolatated from the rear case and then wired to the amplifiers central earthing point.

beautiful ....

was just admiring JH new 686 monoblocks on ebay this week

great price for a lovely unit

wonder what the weight is?

[Mr.Ian]

I saw some monoblocks listed at £3k but dont think they have the Neurochrome intelligent soft start and Neurochrome Guardian speaker protection fitted.
Bet if these had been included the price would have been closer to £4K; the extra parts are close to £500 plus shipping and vat

The amp is very heavy, its a one person lift BUT I wouldnt want to carry it too far. Never tried to weigh it

[Ali Tait]

The monos are the same as the pair I have just bought and they do indeed have speaker protection fitted. Soft start is provided by a thermistor.

[Mr.Ian]

I can't see the Neurochrome guardian board in the ebay pictures

[Mr.Ian]

Looking on ebay you can buy speaker protection modules for under £5 delivered. Neurochrome are, reassuringly more expensive.

[Ali Tait]

It’s not a guardian board, it’s from a different manufacturer but does the same job.

[Mr.Ian]

Precisely

I have a Mod 686 of a very similar spec, if not identical.
It is all the SS amp you will ever need.
