Hi,jh and all. > I've used a 6BC8 dual triode (just like the UA175 compressor), connected 6BC8 is so hard to get here in Japan. and I head that 12AT7 can be used instead of 6BC8. I check Ep-Ip chart, but it looks like don't work well. How do you think about this? Cheers, Motohiko Takeda Tokyo Japan.
