Thank you all again everyone for your help.

I am a little confused by the replacement R101 surge resister. The service manual simply lists it as a 3W 3.3R wirewound resister. Can all wirewound resisters be utilised as fusable / surge protecting resisters? I notice the term 'Fusable Wirewound' and simply 'wirewound' in descriptions for resisters. Is there a difference? The resister I have purchased is wirewound but simply looks like a regular 3w sized colour coded resister. Is this wrong? As a reminder the original part looks like as shown in the attached photo. If using a resister named simply as 'wirewound' 3w 3.3R that looks like a standard colour coded resister is incorrect can someone perhaps point me to a source to obtain the correct part?

Thank you again for helping me out.
