I was in the north side of Chicago the other day, I wanted to try some new tubes to roll in my amp, so I decided to stop at Triode Electronics and check them out, I've ordered from them before, very fast, curteous and very honest and stright forward guys, although also very busy. When I walked through the doors I wasn't sure what to expect, however, the front of their store lists a TV/Radio repair shop, as I walked by the window, I couldn't even see in because of the equipment in the window. I half expected just some store front and maybe some tubes on display, what I found was simply amazing for me. Everywhere...and I do mean everywhere, was tube gear. Loose tubes, tubes in boxes, tube transformers, and a nice assortment of Scott, Fisher, Knight, Heath, Sherwood and other tube gear. I spent roughly two hours there chatting and just admiring the gear they had. On one wall was a row of oscilloscopes, on the back wall was an old display of some very old and HUGE tubes, one had to of been at least two foot tall, and several others nearly as tall, slowly descending in size to your standard 12ax7's. I was looking for some driver tubes for my amp, and I was shown black plate Telefunken, RCA's, Mullards and Bugle Boys among others, you won't see these on their website unfortunately due to customers trying to rip them off by returning bad tubes to them. However, if your ever in the Chicago area, need some nice and somewhat rare tubes I suggest you call in advance and they will get together what your looking for. The best thing about these guys is you never feel they are trying to sell you something, they ask you what you want and suggest something that will work. There web site is http://www.triodeel.com and they have a good selection of new tubes, the good stuff though is by walk in only.
