Thanks for all your help guys, I only had a 3W 2.2M replacement and it was a bit of a tight fit hence why I put back the grubby looking original. The original did measure 2.2M so I didn't think any harm with putting it back. I've got some half watt metal film 1M resistors which I will put in its place tomorrow.

I'm getting all sorts of trouble with the preamp, it's humming and I'm getting 50hz at the output, I wanted to get the power amp up and running before I tackled it.

Thanks again, I've learnt a lot from this amp and even though the sound of it may well be coloured I love how it sounds.
