Hello to everyone, I'm a beginner and therefore, sorry if I say stupid things, and even for the bad English. By now, I've already bought two of these cards: http://www.ebay.it/itm/K-G-dynahibal-KG-Kevin-Gilmore-Unbalanced-to-balanced-preamplifier-PCB/132248796933?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 believing they were the same (but with different arrangement of components) to the thread tab. Comparing the ebay card with this (verse 1.02), I noticed that in addition to the positioning difference of the components, there are other differences, the resistances seem to be inferior and of different values, but most importantly, trimmers are missing from 10k positioned next to the that340 (which I seem to understand, are used to adjust the audio output), while there is the 10k trimmer, near the power input (this I did not understand what to do). What I do, now, the lack of trimmers is a serious thing or I can go on with the pcb I've bought. Where do I find the Gerbv file of the latest version of this card, not that with the smd components.
