Amps
found in the bigger radio consoles and also part of a module line for DIY
systems.
This amp is very
similar to the NF1 amp. There are some minor differences in the circuit design,
but to me they sound the same. Both are rated at 8.5 watts.
In my opinion the NF1 looks better than the
longer NF10, but the NF10 does not use a printed circuit board as the NF1
does.
An interesting fact is
that the output power is slightly higher on 8 Ohms loads, though the amp was
designed for 4 Ohms speakers.
Take care . . .
1. Their output transformers are not too big, so that they get easily in
saturation in the bass when used with unefficient speakers.
2. The selenium rectifier and
the electrolytic caps tend to fail and so the power transformer
is in danger. I really recommend to check these properly and to use
the PT on the higher rated taps (240V for
220V use and 117 for 110V use). |
