Hi Leonfijen,
Start with the basics. Do you have DC supply voltages inside the unit? If not, check the continuity of the primary AC circuit (transformer, fuse(s), power switch .. )
If you have DC voltages, are there any other blown fuses? Is there a large DC offset voltage at either amplifier output?

Hello Leon,

I have just bought a second NAD 705 on Ebay myself.
I hope I will receive it by the end of the week/beginning of next week.
It is defective too, so maybe we can exchange our experiences with repairing it.
I have another NAD 705 with a burnt out (literally, there is a hole in the PCB!) power stage. I just use it as preamp/tuner for my NAD 2400THX power amplifier.
I am really impressed by the sound of this combo. My speakers sound two classes better than with my previous amplifier. Nice solid controlled basses, very open and detailed mid and high.

Is your native tongue French or Flemish?
I am from the Netherlands, so Flemish/Dutch is easier for me than French, although I can read French reasonably. Speaking and writing it is another matter, however! English and German are OK.

Hope to hear from you,

Henk.

Hi Henk,

Sounds good. Original I'm dutch, so the language should not be a problem. Send me some info (fyenleon@pi.net).

Groetjes, Leon

Alas, they don't carry the 705 of NAD.
But I think it is a really useful site, especially since they sell the manuals in PDF format, so you don't have shipping delays.
It may come in handy next time!
