Re: Heatsinking the BS170s in the U2?

Break a 20mm fuse and clean the glass and gunk out of the metal end caps
These end caps are a perfect snug fit on the BS170 body.

Before pushing on, solder a bit of brass or copper to the end caps
to make some mass to sink the heat.
You can see mine in this picture (a curly piece of copper soldered to a cap)



Works a treat (break the fuse in a bag to save your eyes)

I've got four BS170s fitted to my U2 kit and will be getting it boxed up in the next few days.

Is there enough physical space there to fit four of these clip on heatsinks?
