Powering up a 577 for the first time


 

All,

While I was searching eBay for a transistor adaptor for my 576, I came across a parts 577 in good condition with both the adaptor and an original safety cover for a low price... and ended up snagging it, too.

It was advertised as not powering up - and on closer inspection, the power cable's strain relief is loose, and there's no fuse present. I can obviously fix both, but I'm wary of powering it up given that perhaps there's a reason the fuse is absent (although I'm comfortable checking rail voltages with suitable precautions once it's up). Any advice? Would a variac help?

Thanks,

Neil
