Repair of Goldmund 18.4 amp


Hi guys,

Lately, i have some  issues with my goldmund 18.4 amp. It needs to be serviced. I sent it to the local techinian but he told me that he needs a symmetric diagram of the circuit to repair.
I bought it from secondary market and it is too costly to send it overseas for repair.

Anyone can help to provide the symmetric diagram and any advice on how to go about it?

I desperately  need help to repair it.

Your great help is highly appreciated.

Thank you,

Dear Johto,

Sorry,  i forgot to mention that i stay in malaysia and not in US. I need help as i bought it from secondary market. I can not send back to the  distributer in singapore as i m not the original owner or they will  charge me a high repair price.  Can you help to obtain or share the service manual or symmetric diagram with my techician?

Or can anybody help?

Thank you in advance for the helping hand.

Thank you minorl for the input but it may cost me up to 50% of what i paid for purchase of the amp due to the distance of shipping, tax and currency rate.

Annyone can offer any alternative assistance such as service guide or guidance based on experience?

 i was told that goldmund schematics is more complicated.
