Sorry I didn't post sooner (busy holiday season, World Junior Hockey games and NHL games... is the excuse).
Hardware:
cdadapter, iPod, Seeburg 3W1 wallbox, 24 VAC transformer to power the 3W1, 9VDC AC adapter to power the cdadapter/iPod
I ran some quick tests and entered in selections randomly. Here’s what I found.
Power up.
Test One:
A5 began to play as it should
B9 entered in, A5 continued to play
C7 entered in and immediately A5 cancelled (at the start of the motor cycle) and B9 began to play
H5 entered and B9 immediately cancelled then C7 began to play
The cancel button cancelled the currently playing selection each time, as expected.
Test Two:
K5 began to play as it should
A3 entered in, K5 continued to play
D5 entered and immediately K5 cancelled, A3 began to play
D9 entered, A3 continued to play
C6, F4 entered and A3 continued to play
The cancel button cancelled the playing selection each time, as expected.
Test Three:
Selections B5 A8 A10 D7 D10 D5 entered without cancelling any previous selections. The cancel button cancelled the currently playing selection as expected.
Test Four:
Powered down and then powered up
A6 began to play as expected
D8 entered and immediately A6 cancelled, D8 began to play
C3 entered and immediately D8 cancelled and C3 began to play
Test Five:
Powered down and then powered up
All selections played as expected without premature cancellation
Observations from this small sample size:
The premature cancellations seem to occur randomly- unrelated to the selection but always at the start of the motor cycle and relatively early in the order of selections (2nd, 3rd or 4th).
I haven’t added a cap across the AC line (I presume it would be the 24 VAC line).
Rob would you have any suggestions as to the capacitance value?
