I have a mono preamp "Roselson" (Spanish manufacture 60 years) with high gain (ECC81 and 12AX7 tubes), I wonder if my ST70 (original printed circuit board and 7199) accept the connection or if instead you only get much noise.
Gain Dynaco ST70

I ask the question differently. The Dynaco ST70 is high gain?.
When connecting the preamp makes a loud noise and I think is due to the high gain preamplifier next to Dynaco. With another solid state amp does not cause problems.
