Thanks, but I think maybe this can be a best project than others.
PCB and power supply seems very good.

It is nice, but assembling a kit, sold by people whose sole purpose is to make money by ripping off others is not really encouraged over here.

Maybe not. The 7C had a pretty good phono stage and a very mediocre line stage. Its claim to fame is based mostly on collectors value.

Four (4) caps along the signal?!! ECC83 follower!!! I bet it only sounds good with TFKs

Josep,

You better go with an Aikido from John Broskie at:
http://www.tubecad.com/2006/05/blog0064.htm

Choose your input tubes depending of the gain needed
and you'll get better results than the Marantz 7 preamp!!!

Even without a PCB the results will be higher quality and bandwidth!!
And there are on Tubecad many PS's to choose from.

As Analog_sa said: " the Marantz 7 is good for his collector value,
not for his preamp stage... "
And most, avoid diyzone

Regards.
Alain.

1 1/2 12AX7 and massive feedback!

The tube amps the likes of Marantz did in the 1950-60s are the equals to the ss amps the Japanese electonics giants did in the 1970s. Not bad, but you can do a helluva lot better.

Go Akido.

...It's phono preamp isn't bad but the post volume control circuits are veiled. The Audio Research SP-3-6 is basically am offshoot of this. They both evolved from an original Westrex circuit which in some ways was superior to either the Marantz or the Audio Research.
