dynacord amps 600/1000/1600 repair help.

[The Dude]

the clicking sound is caused by open resistors in the power amp section . R122/123 100w 4.7ohms , i hope it will help someone .

There are 100W resistors in this amp?

I will see on Monday, what can I get you.
Dunno about the hex file, though. I reckon , that one will be a no go.

Hi,

Do you have any information?

I have explored all my options, but I was unable to obtain the file. You will probably have to order a pre-programmed controller from Dynacord. (Personally, I think that it's not available at all. The BOM specifies very few orderable component level parts, the Atmega 48-20 is not on the list)

Hi,

Sorry, maybe i made a wrong quote of original message...
My question was about service manual or photos of SMPS and amplify board schematics. (Powermate 1000/1600 - 3 (mk3)
