I am cleaning up my work benches and the following have emerged from among the dust bunnies:
3 x Tent Labs 11.28960MHz low jitter oscillator module
1 x Tent Labs 16.93440MHz low jitter oscillator module
SOLD

2 x used, tested LL1689AM/PP line output transformers
These can be used to make a very special sounding headphone amplifier. Circuit found here: http://kandkaudio.com/images/PP%206H30%20headphone%20amp.pdf

2 x used, tested LL1689AM/PPZ line output transformers
The "Z" on the end of the part number means that there is no added "air" gap, although there is one, in any case, due to microscopic roughness on the C core halves' surfaces. This results in maximum inductance for this type and size of core.
