Hello all just seeing if anyone can help me with an issue. I have completed one of my new group buy KLM-367. Now it is installed and I am attempting to calibrate the board. I have completed both the power supply calibration and Step (1) resetting. Now with step (2) the D/A adjustment I am running into a problem. I set SW1 to test then toggle the Tape SW and LEDs 1 and 5 turn on. rotating VR7 or VR6 does not change the state of the LEDs. Any clues? Also has anyone run across a mod in their polysix where on the 369 the trace between D1 and J2 has been cut and then a jumper wire was installed to another location? I have a loose jumper wire coming from D1 for the time being I have soldered to J2 until I figure out why and where it was rerouted to. - Daniel
