Re: Dynatron Jewel TP30 - first attempt at repair/restoration
Some progress on the Jewel. I've pulled all the electrolytics from the PCB and tested their state of health.
Here are the results according to the LCR-T4 component tester:
CCL 350uF 9V(?) - open, dead
CCL 2uF 50V - 6.9uF ESR 9 ohms, Vloss 11%
CCL 8uF 50V - 9.3uF ESR 0.14K ohms, Vloss 20%
CCL 8uF 50V - 14uF ESR 1.8 ohms, Vloss 2.3 %
Plessey 100uF 6V - open, dead
Plessey 100uF 12V - 113uF ESR 7.2 ohms, Vloss 5%
Dynatron did not make this servicing job easy as all the component leads have been bent over on the copper track.
Next job is replacing all 6 caps and hopefully the low audio output will be fixed.
