Hey guys,
This forums has been pretty quiet for awhile so I thought I'd start asking some questions!
Here's the skinny:
I'm building a pair of Ikes. I've ordered most of the parts already and I'm in the process of ordering tubes which is where I'm hitting some stumbling blocks.
I want to use the 6CA7 big bottle ElectroHarmonix tubes, based on the glowing reviews here and on other sites.
If I use these tubes do I have to adjust the bias using R29, or does it remain the same (resistor value of 3.3K)? Do I have change anything major, like transformers?
I'd also like to use the 6SL7 pre-amp tubes, just for the look of the 4 octal tubes. I've noticed there aren't a lot of options for the 6SL7 from the normal 'retail' outlets (Uncle Neds, thetubestore.com, Angela), but there are some. Right now I'm thinking of using the United Electron (sylvania) on Angela or the Sovteks on thetubestore.com. Should I avoid the 6SL7 becasue of the limited selection or would one/both of these do just as good a job as the 12AX7? Any suggestions on which might be better if I do go with one type of the 6SL7s above?
That's the first round of questions that I have, but I'll have more as time goes by. Thanks in advance, guys!
