Jef and I have corresponded some about me building my own Darling amp. He has given me great pointers and insight when I go to build my own. That is one thing that I really admire about Jeff, that he is willing to help and answer the "stupid" questions that we newbs have. The first three amps I'd like to build are the 6EM7/13EM7, 6197 Spud, and a stock Darling. Then on to an EL34 SE to replace the one I got from Wayne that UPS damaged. I've got a tubes for everyting. But, unfortunately, funds are limited, so I'm starting to round up parts here and there with not enough to build anything yet. Soon, soon.
