Dear all,

Regarding the posting above which I placed a couple of weeks ago, I'm 
glad to say that things are now working normally again.  Bill Tracey has 
over the past couple of weeks sent me numerous e-mails guiding me on how 
to trace the fault.  Without his help I'm sure I would have had to 
replace Ozymandias, however, following Bill's instructions I was able to 
trace the fault down to one individual component, R12, costing just £0.88.

Thank you William and may you have many children.

Jeff Cook, G0AFQ.
