Just a little pair of monoblocks [emoji1787]

[andyrlb]

Just collected these , the guy said they’re a bit heavy ! HEAVY!! I reckon 60kg’s each

1000w each too , I think I need to let the National grid know before I plug them in ( not sure I want to )

Built by a medical doctor who’s passion was electronics and especially hifi .( now deceased)

The son explained that they’re 1000w each and drove a set of 4 speakers, the 2 front speakers were around 6” tall and he used some ATc’s as the rears , apparently each one has triple outlets, treble, mid and bass , the builder had altered them at some point ( whilst Alzheimer’s kicked in ) to be bass and mid/treble , might explain the brown wire that’s lose .
I’m a little nervous about powering them up , what do reckon?

They look vaguely familiar somehow. I wonder if they're anything to do with Colin Wonfor?

The son thinks they’re a Lindsley hood design.

Got this one too while I was there …

So much power for speakers so small.

Do you have a friendly electrical engineer that can have a look at them for you?
If not, then be very careful. Being modified by someone with Alzheimer’s would concern me. They may be perfectly ok, or they may not.
Did you ask his son when they were last used?
Do you have a copy of the circuit design?

Fear not I’m not going to power them up at all .
Last used around 10 years ago and built around 20 years ago ( transformer dates to 08/99 )
To be honest I didn’t realise just how big and heavy they were until I arrived to collect them.
No circuit design or schematic available.
The son thought they were a lindsley hood design but I think he meant the other little amp that came with them ( pictured)
I think my best option is to strip them for the transformers and sell them which seems a shame .

a bit of a frankenstein's monster that... would be good to get them looked at by a pro.

Totally agree Grant , my initial thoughts were to simply transfer them into more modern cases but clearly not an option for one as simple as me but for a pro they may potentially be desirable.
The son said the sound was incredible and his dad would have fellow hifi nuts coming to hear them.

I would find that a daunting project. The construction is rather messy, and th condition speaks for itself - a hell of a lot of work to do there to fell comfortable using them.

I see the parts are for grabs at diyaudio. So you haven't powered up?
I would be scared too tbh.
Also these heatsinks would be wasted on a 1000W amp. Better to to convert to some toasty low wattage inefficient class A amp. Well, maybe not that low wattage after all...
