Reparando UHER Z124 alimentador para UHER REPORT series

Excellent Power Supply. I have purchased this power supply from an old junk shop in Kolkata. Then I have no idea, where the power supply came from. But now I realised the source. The power supply has a blown and broken fuse. I replaced it with an identical glass cartridge fuse and the power supply is working normally. I purchased the power supply in 1988. Till today it is working normally. Thanks for the circuit diagramme. I have taken a screenshot. This will help me in the future. I do not like modification. I always try to maintain the originality of the old equipment. Thanks a lot for this upload again. [from Kolkata(Calcutta), India]

Very nice, but most important is the change of rectifier to modern silicon low loss type, change the capacitor from 1000uF to 4700uF/10V (same size) change 2 diodes to schottky. This will fix most issues and provide more voltage regulation for more recent recorders.

Ah, helpful, now I know there are screw under the label, that's how you open them. Cool! You know you don't need a cable? That these power supplies fit in the battery compartment? At least the Z114 does on the older Uher 4000-L.

Для зарядки аккумулятора, что бы не вынимать его из магнитофона. Не батарей, а именно аккумулятора, простые батареи не заряжаются.

Compatible con REPORT 4000L?

3 минуты 45 секунд, "Also works", но не контролирует ток заряда аккумулятора и блок питания может сгореть.
