Hi Tim,
Ihave a T15 which has been working great up until last week when the phantom power stopped working. When I try and use it, I get a low hum. I'M sure it's a case of re-flowing a joint but if you could point me in the right direction it would help.

Thanks


Alex

Phantom power switching is shown on page 2 of the schematic. Re-flow the solder joints at D15 through Q1/Q2.
