Hello!

I was soldering components into the K-rock phaser board, when I discovered that the big lot of BC560 transistors I bought are suffixed with a "B" instead of a "C". Checking the triple chorus boards, they're all "B" suffixed as well, and they're all neatly soldered in! Is this likely to have made a difference? I thought I'd bought 560Cs for some reason, grumble grumble.

C types have higher current gain.
In most cases, the B types are more than good enough. I just specify the C type because you can get it for the same price as the B type, and it's closer to "ideal".
