John McClure has requested an "A" test roll. I don't have one for
sale, but I can tell you that most tests on the roll can be done quite
simply by placing masking tape on the tracker bar and merely poking
holes in the tape as needed.
Also, on the "A" piano, the technician can do most tests by pulling
tubes off the cutout junction. With the tracker bar taped closed, the
technician can stay in one position, with gauges, under the piano,
pulling tubes off the junction, to verify and regulate most functions.
What tests do you need? If you need something special, write to me
off-list.
