This amp is the result
of a joint venture from PE and Dual who were very famous for their
turntables (remember the Dual 1009 and 1019).
As both were also
famous for the low price market it may not surprise that this amp does not
have an input for MM pick ups (ceramic only).
But: This amp is not
bad at all. The iron quality is fine and seems to be supplied from a third
party (looks like Telefunken or Telewatt). And: This is the only one of all
vintage stereo amps from Germany that uses a choke in the power supply.
The circuit is pretty
simple - good. Due to a slight "loudness" the (passive) tone controls should be turned to
- bass: 2 o' clock
- treble: 10 o' clock
to obtain a linear frequency
My unit is in nice
original condition and delivers 7.1 watts per channel from the original
Lorenz ECLL800 and Valvo ECC808 tubes with very low hum and noise. The OPT
has only a 4 Ohms tap, but it also works and sounds well on 8 Ohms loads.
The volume pot is not
perfect in the lower range, but this can be compensated by the balance
