My Armstrong 521 Stereo Amplifier Circa 1968-1972 

Decided to re rivit the speaker connector with J B Weld on the broken side and a washer just bigger than the rivet for support

Cheers for the video Harvey. Never seen inside one of these before,lots of caps😮

Great Little Amp Harvey Make Sure You Take Out The Plug in Boards And Clean Any Tarnished Edge Connectors Also Check The Power Board For Any Blown Speaker Protection Fuses The Al102 Transistors Are Very Expensive To Replace But I Think You Can Get Russian Replacements ....mike

Sounds to me like the output transistor may have gone down. If so, you may have to replace both of them with a matched pair, Harvey.
