Good morning all together,

unfortunately my quad 44 has a faulty transformer. It hums real bad. Therefore I am looking for an appropriate replacement.

Could someone pleace provide the electrical properties needed for the transformator? I measured two times 19,5 V AC but i am not sure if those values are ok.

Or could someone recommend a replacement for the transformer?

Thanks and kind regards

That seems a little low. Was that a loaded measurement, or unloaded?

It was measured in unloaded conditions.

I the schmeatics it is shown, that a DC Voltage of 15V is needed which means, that the transformer should have 21V at least right?

Unfortunately nothing specific about the transformer is mentioned in the repair manual. Besides that its code is T400.

Does someone know a good replacement? Or specifics about the transformer? Voltage / Current etc.

Thanks in advance!#

Konstantin

We sometimes have them in the shop here. I don't see one at the moment. If you contact me offline I may be able to help you another way.
