gus	Re: Solens and power supply ghosting Hello Dai I have not been here for some time. Years ago I installed solens in my laney vc30. I used 1/2 the cap of the plate and screen electro value. I posted about it here maybe four or more years ago There can be a few problems using solens One the ESR is so low the surge currents in even a solid state rectifer amp can cause problems. In my case the torrid PS transfomer did not like the solens because Torrid don't like unbalenced current surges. I "fixed" that with a 1 ohm resitor in series between the diodes and the first cap. I also think it can show grounding problems because of the low ESR. FWIW a 20Uf atom is about 1.5 ohms ESR on a lc102 a solen measures 0 ESR. Two size
