The heatsinks come with various pre drilled and threaded holes two of which are used to mount the PCB.
These units came to us already assembled as seen in the photographs, we believe they were to be incorporated into a high quality audio amplifier but they were never actually built.
The assemblies are stored with us packed loosey in manufacturer’s tote bins, they are unused and the component parts are in very good condition.
As they have been in storage for some time and are loose packed we have classified them as ‘new other’
PLEASE NOTE!
These units came to us as partly assembled unused surplus stock from a manufacturing Co. they have been kept in storage for a time, we have therefore classified them as ‘new other’. The component parts are however pristine, the units are stored with us still in the manufacturers tote bins. The photographs are representative of their general appearance being of some of our actual stock, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
