TR5 power on; Red lead 9.5v; Black 1.83v; Base(?) 1.95v.

Should I not be testing these components for resistance off the board?

PS Thanks Geof. The OC81's are currently off the board. Battery levels for the minute or so checking for voltage has remained stable - same before and after checking (so far). But with OC81's attached, there was a drain - it drew the PP9 down from 10.1v to 9.1, which has since recovered to 9.93v.
