These have been sitting on my worktop for over a year.
LM4780 amp. Needs little introdution. Never used, or tested even. But the PCB is populated and complete.
£35 + P&P.
-----------------------------------------------
Stepped Attenuator - 12 steps
Built with quality Welwyn RC55 resistors.
Resistor Values:
1 - 0
2 - 100.2R
3 - 154.1R
4 - 226.2R
5 - 332R
6 - 464.4R
7 - 681.2R
8 - 1k0R
9 - 1K54R
10 - 2K74R
11 - 5K11R
12 - 12k08R
Used once for testing, but not enough steps for my liking.
£15 + P&P.
-----------------------------------------------
Mic Wand fitted with Panasonic WM-61A electret and phono connector. Wired in reverse (ala Linkwitz mod).
Used condition.
£5 + P&P.
-----------------------------------------------
Prototype preamp PCB
This is the protoype version of the mic preamp sold on madaboutsound.com, as seen here:
Note it does not come withe above enclosure.
In used condition and needs some minor attention as it has no input RCA connector, or battery strap. Would be perfect for someone on a budget.
Output connector is RCA so would fit above mic wand perfectly.
£10 + P&P. |
