I inherited a Quad 34 pre that weirds out now and then. The preamp
comes on, with the default source selected. Either by itself, or when

Hi Nicolas

Lucky inheritance.

From recent experience (although these things change!) Quad themselves will
offer good advice either by e-mail or by 'phone and there first tack doesn't
seem to be "send us a blank cheque and we'll fix it" Might even send you a
copy of the relevant circuit?

BTW, does this thing sound ok? I am a bit put off by all the tl071
opamps that populate this thing. Aby recommended mods?

Sound is OK - a wee bit noisy compared to recent designs but a v. good phono
stage if my memory is intact. Not sure about the tweekability - in my
experience it almost always results in a worse sound than the original.

Have fun with it
