Hi Chaps,
I have to offer two excellent high quality headphone amp modules with stepped attenuator - built using precision foil resistors!
Uses the well known 4556 headphone amp IC.
5 position rotary switch stepped attenuator in 6db staps: [Attenuations of 0db, 6db, 12db, 18db, 24db]
All foil resistors for excellent sound quality.
Ex very high quality Sony broadcast equipment from 1980's, when Sony very serious about audio quality.
Requires +/- 15V power supply and signal input - very easy to use, you can build in to an existing project for a headphones output.
A great way to make an excellent little headphone amp with little effort!
It could also be adapted to be used as a high quality active line or buffer amp. Of course you can experiment with changing the op-amp if desired.
Price is GBP15 each (well worth it for the foil resistors alone)
+ shipping UK GBP4.00, Europe GBP6.00, Outside Europe GBP8.00
Please PM if you'd like one (or both).
Two only, so be quick!
Cheers,
Rob
