Repair Bose PS604A

Hi,

I have a Bose PS604A that need a new PowerSupply Board. I don't know who can supply parts for Bose professional amplifier...

The board have multiple burned Components (cause unknown):

transistor Q206 (unable to identify reference)

resistor R287 (unable to identify value)

capacitor C312 (unable to identify value)

Other parts may be damaged like U207 and U208...

I think that it may be more cost effective to just replace the board than trying to repair (but I can try).

Is it possible to acquire schematics or service manual for this kind of device ?

Can someone advices me to know where I may be able to buy a complete PS board ?

Best Regards,

JMB

 

PS: sorry for bad English , not my main language.

PSS: I can join picture if needed.

Re: Repair Bose PS604A

Hi JM,

 

I would suggest having this sent in for official Bose service. This might just mean a replacement is to be sent. I'm not sure where your regional office is, so I would suggest contacting one of the following emails or phone numbers from this list: 

https://pro.bose.com/en_us/support/product_and_technical_support.html

If you're in the US or Canada, you can call 800-994-2673 or email prosupport@bose.com

 

Best regards,
