Make your interstage caps smaller if you already got expensive output caps that could be smaller to your line load. Any extra strong filter will mean op amps or other active elements. If you want to go that route, classic op amp filters 24dB are just a google's stroke away.

I'm not comfortable changing the interstage cap, I think the problem is the output cap because my Erno Borbely preamp has an input impedance of 1Meg so for 3.9uF output cap the optimal low frecuency reponse is 0.41Hz, with a output cap of 0.08uF will be 20Hz & fix the problem, right?

P.S. What about the sun, beach & drink?

No you don't have to change your expensive 3u9 silver & gold in oils. We can pre-shape in the Teflon interstage. See 33n interstage, 3u9 out, 1M load.

About new avatar, this is from Stalker inside the Zone. Classic Tarkovsky as current incidents remind.

Hi Salas

Your obviously a fan of the movie.
I've been waiting to ask someone this a while.
On my DVD copy there seems to be an incredibly subtle wobbling type effect going on with the B&W bits at the begining.
I can't work out if it's a bad DVD transfer or in fact an original Tarkovsky optical effect.
Ever noticed that.
I find it very weird, and no my TV's not on the blink.
Great soundtrack on that film.

Simon

There is in mine too. Must have been the telecine transfer machine.

3-3.5Hz -3dB, but well down at slow disc warp.
