"This amp came in for a good service because, although
the amp was working, the owner was concerned at the amount of "popping
noises and kettle sounds" that were coming from it. I changed all the components, except
for one wire wound resistor (these are usually ok), and believe it or not the main smoothing capacitor
was still perfect! All 3 original Mullard tubes were fine too (including the
EF86........uhh, not one of my favourite valves!!).
After its service, the little amp sounded great. She is as good (actually better) now than when she was new. Not a blemish of noise anywhere.
