Great video thanks! Just curious, how did you deduce that those certain capacitors needed to be replaced? Did you measure them directly or how? Thanks mate!
Yeah I know. It would be safer with 'em, but my brief was to get the amp going with only the most necessary changes. So I kept the circuit original, and only replaced those worn out electrolytics.
I always muse on Marshall's model numbering system and wonder what the hell they were thinking. Indeed One would be hard pressed to come up with a more confusing model designation system if they tried to. The decision to give the different versions seemingly random 4 digit model numbers that begin with the number 19 was a master stroke in ambiguity. "Is that a 1987 or 1986?" "Oh no its a 1959 made in 1969"! And the most famous Marshall? The plexi of course, wasn't an actual model but a nickname. Lol. "Is that a plexi?" "Well its a 1959 but its from 1971 so its not really a plexi but its the same circuit!"
According to the current Australian legislation and Australian Standards, it is mandatory for all 240V AC mains powered equipment to have an earth wire that is securely bonded to the chassis for it to be legal.
Really nice amp. What a pain to replace that can...
I read somewhere that those old round Bulgin/Belkin plugs are no-longer considered safe to use for 240V AC mains and have been de-rated to 50V AC.

Great job But No Screen Grid resistors ?

Hahaha. Yeah, my thoughts exactly.
you destroyed this amp
You did a great job Mark, thanks a lot:-) Now for some AC DC :-)

You may be able to loosen the clamp on the cap and lift it up high enough to get at the wires
Pommie-Amp 😂, nice one 😅!
Mains earth wires can either be Green, or Green/Yellow.
