Kenwood T-58L Tuner.
« on: February 02, 2019,12:04:26 »
Hi folks,

Had one in as part of a four part stack where the the display didn't work though the other three displays did. Checked manual where noted display filament uses two 120 Mfd NP caps from an AC supply. Caps suspect so thought 250 Mfd NP Ebay.

Display still dim compared with the other three displays, but noted when in S/by only the tuner one works to display time, so guess a bit worn out.

Next fun was on radio only Sound reduced to near mute, though on other inputs OK. Adjusting volume up or down caused radio volume to recover for a few seconds, then fade again.

Thought run for a while where after an hour or so, radio volume became constant. Tend to suspect caps in the tuner.

Wonder if anyone has had the issue ? - Thanks - Chris.

Thanks Jordan,

Replaced them with 250uf NP as display worn out with set in s/by.

Guess sort the sound issue with freezer and a hairdryer - Chris.

Thanks Jordan,

Been there - Chris.

PS - Eventually found C312(2200/35) drooling at the bottom - Sound now OK - Suspect as the main cap on the board, there was supply feedback to the main amp giving the issue.
