Vincent SV-236 with distorted sound

I got an annoying distorted sound in my Black Beauty of a SV236.
It began after 5-6 years of normal use, and affected both channels, but not evenly. It became worse over some time, but could disappear at higher Levels. Sometimes it was quite fine for some periods.

Okay, I ordered a new set of tubes, replaced them and put on my newest CD with David Gilmore.
That was some letdown.. the distorsion was all over again, and David's guitar was coughing.

Once again I took my SV236 to the bench and dismantled the covers, connected a scope and monitored it over some time using sinewave, sawtooth and square signals.

I found out that if I pushed the Loudness button it could be fine for a long time, but then suddenly the distorsion came back. The sine wave looked as someone was blowing at it right beneath the right top of the curve, making turbulence with the downgoing beam.

Right, as the problem seemed to be affected by the Loudness, I replaced the 12V signal relay behind the Volume pot motor (yes it's inside the black metal housing).

This was not doing any change, but after a round with my upsidedown screwdriver tapping Components from the front to the back of the printed circuit boards, I came to the speaker output relays. And then, when tapping these relays, I realized that I was mislead all the time, this was not a common left/right side problem, but two individual relays failing at the same matter and time. OK they were probably twins, but seriously...

Long story short: My SV236 plays clean again, with two new output relays setting me back some 15$.
I'm happy again. And David's guitar is crying again.
