Published on 04/14/14 at 02:44This is a usable analog preamplifier HiFi (after a few improvements).
UTILIZATION
Simple manual, obvious connections
SOUND QUALITY
No staining but various noises (bad bad power transformer and filtered)
It can be improved very easily, in which case it becomes great:
- Change the voltage by an impregnated model (planar transformer primary side 2 x 115 V 2 x 18 V 18 VA Spitznagel SPF SPF 1,831,818 1,831,818).
mount the transformer on small foam pads
- Change the filter capacitors by 600 μf/50v.
- Replace the original op amps by NE5532P (4)
- Thoroughly check all welds of the device (it's made in China).
total cost of changes: 25 euros with shipping!
The sound becomes perfect: more noise, more breath and RIAA entry worthy of the name
OVERALL OPINION
very good buy if small modifications, simple but thorough is performed
The next step in customization will be the replacement of all chemicals and other knobs and switches capacitors,
