Marantz 2250b transformer replacement

[Lambchopin]

New to Marantz and to AK. Just purchased a Marantz 2250b with a known burnt transformer. Any ideas on finding a replacement? I see a 2270 transformer on ebay, but am wary of using that as a replacement as the voltages are a little bit higher. I've contacted oak tree vintage in Colorado, who has a 2245 transformer, but he advised it would be ok to go higher in value, but not down. Any help would be greatly appreciated.
Thanks

Welcome to AK and to the Marantz forum! Hopefully someone will have a donor and can source you one. Good luck!

I think it is best for you to stick with an exact replacement. I believe that the power amp bias voltages are particularly sensitive to the supply voltages it is receiving. You may not have enough adjustment in the trimmers to establish the correct settings. I am still just learning the analog circuits, so if I am wrong, anyone please correct me.

Marantz 2250b transformer?

Thanks gentlemen,
That's what I was afraid of. What are your thoughts on ordering a new Hammond replacement from Mouser or elsewhere? If so could anyone tell me what the output voltages are supposed to read. Maybe I'm missing something, but I can't see clearly what the output on the secondaries is supposed to be for the 2250b.
In the past I've had parts in place for reference and more literature to guide me along, but the receiver arrived with all the wires cut, and the primary is burned, so no chance of testing voltages.

Also, not sure if this is the right forum to ask, but I'd gladly pay for a transformer from a donor unit as well as shipping, of course.



Thanks

Hi Lambchopin,

Try Gary at Transformer Rewind Service, he rewound my 140 amp transformer.
