Hi Folks, anyone here build their own tube mic pre? If so what iron have you used? The JT-115K-E from Jensen seems to be whats recommended, but has any other iron that's been tried?
If you're interested and can comment, take a look at this link at let me know if maybe the 850L or 850N might do it. These are $125 CDN each, and can be had locally. Specs do look pretty good 20hz - 20kHz +/- 0.5 dB (although it does say that units with impedence above 5k MAY be down 1db at 20khz. The spec also states 1.5% THD at 20Hz when the transformer is running at FULL rated current. Thats not too bad at that low freq...
