Romy, I understand that at some stage you trialled a number of different capacitors and settled upon Electrocube 950B/D not necessarily for the Melquiades but perhaps for some other project.  I was wondering if you ever experimented with different coupling caps in Melquiades?  Oil caps in particular.

As I mentioned earlier in this thread, these are my first valve amplifier builds so I have not messed around with different coupling caps before but I have heard how caps in speaker crossovers can make quite a noticeable difference, so I am interested in your input here.

As much as caps in speaker crossovers makes deference, so do they make in coupling applications. In Milq the cap is light duty as the amp never goes A2 and the cap is not change the polarity, still the coupling caps do mater a lot. I did experimented a lot with the coupling caps and I like the Electrocube 950B and MultiCaps, the last unfortunately available only by small values. I did not experimented with new German Teflon caps. I do not like oil caps, at least those that I tried. I feel that oil caps are more suitable for high current applications. Also, do not forget that in context of DSET the coupling cap behavior is kind of defend. If you need large coupling cap for LF amp that you do not care how “dry” it sounds at HF. I find that for MF and HF it is better do not have cap at all, that why in my DH channel I use DB coupling, something that I would not do for ULF….
