Our hard to find - ultra high quality tube tester resistor / calibration sets (generic kit photo, parts may vary per description)
*****New version of the master kit - now more affordable!*****
Several of the original components of this calibration kit went "end of life". I designed up this new kit to replace my previous. In doing this, I was able to reduce cost a bit but provide a better kit overall. We now offer just a single kit that covers the 700, 707 and 747 | 747B

Calibration instructions are available for the B&K700, 707 and 747 with this kit. You can also find these instructions in the manual section of our site.
