Grundig Preamp

This is my preamp. I was very happy to get one. This was a projekt from GRUNDIG in the 80's. The preamp is handmade. There were only 1000 pices built. My amp has the series No. 170. This amp is totally neutral.
They use special long life tubes with gold pins and FINE ART logo. The tubes are double triodes like ECC81.

This is a view of the ampifier output board.
