Yes Salas, this is one with your Shunts.
I saw Martina using those cristals inside the Garrard TT in Krefel and I also met another guy who sold them and had a really "dead" sounding room full of those..... Piramidal effect ?!

Ok, I have to do some catching up here. Circuit in post #5083 on first glance has same problem, T19&T21 with T20&T22 forms high impedance ccs'es and currents are lost again. Will put it in sim to check first. Post #5097 looks promising, were do bases from T19&T21 goes to ?

Yes, 5097 will work very well. T19, T21 are ground referenced cascodes. i will draw that part for you in a a minute. If we could drive that cascode too from somewhere is not clear at the moment. In this case i would rather say not.

Got it, I will copy that part from T20&T22. Sorry, #5083 doesn't seem to work, finding working points are almost impossible.

Hi Ricardo, I would not. Tantals are very sensitive to the wrong polarity, and the 1uF is used in the servo if I'm not mistaken so it may see both polarities.... you could put a bigger cap and reduce R48 accordingly, for example.
(have a bunch of these caps, should have put them in the bag to you... if only I had known.... ;-)

Eager to hear what yours sounds like ;-)
