I own the MKII, which has 1 set of test jacks per channel. I’m not absolutely certain but I think the MKI is the same. Pre heat the amp about 20 minutes before adjusting. Use a volt meter and connect the negative lead to the left jack and the positive lead to the right jack. Turn the adjuster screw clockwise to increase the bias (counterclockwise to decrease). Depending on the tubes you will be adjusting the bias to about 300 mV. Repeat for each channel. The adjuster screw is very sensitive so proceed slowly! You are only adjusting the EL84's (output tubes).I'm also interested in NOS tube recommendations if any other RM-10 owners would care to respond.
