Please forgive me if I'm straying off line here. If I'm shot down in flames
I'll know better next time.
I'm having a clear out. None of it is speficically lf related, but some
metalwork might be of particular interest. I have some water cooled
heatsinks, roughly 250 x 200mm and 500 x 200mm, made from aluminium about
10mm thick with a thicker centre section which carries 4 stainless tubes for
water. There's also 4 into 1 manifolds and flow switches and other bits to
go woth them, as well as some cover metalwork so you add the front/back
panels to make a really nice box. The heatsinks are drilled to take 6 or 12
pairs of standard 'helicopter' rf power transistor packages which makes them
useful for hf/vhf amps as well as having plenty of holes to use for plastic
power transistors. In commercial use they were cooling about 1kW dissipation
continous - they're left over after the rf sections were transferred into a
different case.
I've no idea how to price them - professionally I expect they would be many
hundreds of pounds each. I'm open to offers or trades - all money will go to
charity anyway. I'll try to sort out some pictures over the weekend.
