I got my BC640s from RS, you have to buy them in multiples of 50, but they are not at all expensive.

Do check the pinout of the BC640 before fitting it. Unlike the original AC128s and the 2N3906s it is not 'base in the middle'. I will try to get a photo in my flickr account over the next few days showing how they should be positioned.

I assume the trm you are talking about is the bit aroumd the switches at the top of the controls panel. Mine has 10 screws. And one of them goes into a bracket on the deck chassis and has to be removed to get the amplifier out. I think that's mentioned in the service manual.
