Dusting off an old project and I need a replacement varactor (AM tuner). The original part is an MVAM108 which seem to be as rare as hen's teeth. I found a HAM guy in the US selling some but he won't ship internationally.

Anyone have any suggestions of either where to hunt for one or alternatively could suggest a replacement part?

Edit: a third idea would be the ability to test the component. I'm assuming it's shot based on other factors but I'm not entirely sure how to test it.

Not exactly the same, but similar specs:

440pf at 1v, 15:1 tuning ratio, breakdown voltage is a bit higher, etc...

That's probably close enough to be useful, thanks Dave.

However, being US stock, it attracts a 15 shipping charge to the UK cry

Don't fancy buying me one and posting it to me do you? hihi
