[QUOTE="Qualityten, post: 619100, member: 17776"] I've returned to my amp like this over the last few days. I also removed the EF86s, volume and tone controls. This also removes the hum problem it had before! With a line level input from a CD player into just one ECC40 as phase splitter, there is not much volume. If the input goes in before C10 to the 2nd grid of the first ECC40 it is plenty loud. Of course this is still with the original PPP arrangement, and only mono, whereas stereo would be more useful. Mars, do you have enough volume with the CCDA 6SN7 preamp as driver? [/QUOTE]
