Classic TDA1541a DAC.
(re-advertised due to being let down)
I built this not long ago.
It has a non-ferous case comprising of 3mm thick aluminium sides and 6mm clear acyrlic top and bottom panels.
Two oversize transformers, one each for the analog and digital power supplies with quality components used throughout.
Quality Ampohm Paper in oil coupling capacitors.
National Semiconductor LME49720HA dual opamps in the output stages, these are the TO-99 format metal canned military versions.
These are of identical specification to the LM4562HA.
Sounds very good.
£150 plus p&p
