Brian Watson sold his last replacement drive belts ever. Here is his statement from the csa8 newsgroup:
I have just sold my last EVER pair of replacement drive belts.If anyone knows of any places on the ‘net where I am listed as being a
reliable and cheap supplier, please get me off it because I’m not any more.
Thank you for supporting the CPC with the replacement drive belts for such a long time!
UPDATE: You can order replacement belts from CPC in Preston, Lancs. The product is called AVBELT6.
