Accuphase A-48S

What can't I see the photo's. When I click on them it just takes me to Onedrive

@imhififan 

Would it be possible to convert the A-48S from 100V to 230V given that it has a soft start #716-0962-01 requiring a replacement transformer?

Could you advise what the wiring changes would be to the transformer to convert the primary winding to 230V

Thanks, Andy

Thanks @imhififan 

I might be a bit slow, just what would I install on J2, as it only has a single tab.

Also, I believe that the standby circuit transformer has 3 pins on one side and 4 on the other. Does this suggest that it may be a center tap so can accommodate both 100V and 230V? It just needs wiring up differently.

Not being experienced, how would I go about finding a replacement transformer?

Thanks in advance for any help you can give.

Cheers, Andy

Thank you. Makes sense. I was going off the specs on the NMD website which says that the transformer is a 3 pin input 4 pin output.

HTP-35-12 transformer.

Looks like there are a lot of transformers available that will fit this package format from various manufacturers with a good selection of output voltages.

I'll continue to use my amps with a step down transformer for the moment, but think I will have a look at converting to 230V sometime in the next few months as it sure would be more convenient.

Has anyone measured the output voltages from the transformer, do you know?
