I have a NAD 1130 stereo preamp for my system.
The power amp is an Adcom GFA-555.
While trying to install a rack mount tray for the NAD, it stopped working.
I tried to take the NAD to repair shops, but they charge a 50$ non-refundable fee, and say that they most likely won't be able to fix it because the unit is so outdated.
I need a good quality pre-amp, but don't want to spend more than 200$ on one. I'm fine with "vintage" pre-amps.
The sound I got out of the NAD and Adcom was really nice.
There's an Adcom GFP-555 preamp, but compared to the 300$ price of the NAD on ebay, the Adcom pre-amp is less than 100$, which makes me think that it is not as good quality.
