Philips cd 304 Mains Transformser

wckong · 7th May 2007, 03:13 AM

I need help for my damaged Philips CD 304/01 mains transformer (220v 50Hz 30W). Can someone kindly provide me specification or schematics for this part# 3112 318 39711 (WA 514) so that I can ask someone to re-wind it.

Hi, Bernhard
Glad to learn that you can offer a replacement transformer. Please advise the total cost & payment method. It would be much better than asking someone to re-wind the damaged one. You may contact me by :
wckong1950@netvigator.com
By the way, i would like to thank all who response to my Post#1

Hi Baleuq,

Thank you for sending the handy Philips cd 304 SM which cheered me.

Best Regards.

.... and is it similar to that of CD-104?

Hi Oshifis,

Thanks for your reply to Post#1. I suppose the configuration of cd 304 & cd104 are similar in respect of the mains transformer, for the power supply unit uses the same type of three-terminal voltage regulators.

I wish that I won't mislead you, since my knowledge in this field is limited. Maybe some other experienced guy could tell the true story.
Anyway, thanks again for your two posts in this thread.

Best Regards.
