I had two of these radios experience the "left side problem". Bought some repairs parts, was able to fix one, the other not so much. If anyone else has one of these radios, these may help you out
(1) 1 x DC Jack P/N E03-0170-05
(2) 2 x Electro Cap .22 P/N C92-0876-05
(3) 2 x Electo Capapc P/N CE32CL1C220M
(4) 4 x Electrolytic Ca P/N C92-0092-05
$15 bucks shipped. My radio needed two caps, C406 and C420, which I replaced with the C92-0876-05, working fine. Yours may be different.
