Thanks,

I will file that one for reference.

I'd still like to know if anyone has a way to buy a few odd chips/etc from people in the UK, like Rapid (as linked above), and avoid the absurd shipping charges to the US? They appear to be designed to discourage non EU sales since those would get a flat rate of a couple euros for small packages/envelopes.

In mean time, I found a bunch of canibalized and checked chips from a local ebay seller cheap (10 @ $18 with free shipping). They appear to be a mix of O & Y series chips that came off the same amp and according to the dealer (an electronics repair person) they are interchangable. Obviously, if anyone knows otherwise or can confirm that it would be a good thing.

Thanks again,
Lee
