We Purchase Surplus Stock!!!

If you or your company has items similar to the above, or indeed any electronic components surplus to requirements, please contact us with details as we are keen to increase our stock profile.

 As many of our lines come in to us as surplus – sometimes from high end ‘Milspec’ type manufacturers we try to pass on our savings to our customers – often selling industrial grade or military spec components at a fraction of their original cost.
