Graaf OTL 20 FOR SALE

For sale a GRAAF OTL 20 POWER AMP.
The GM 2O power amplifier uses an OTL (output transformerless) and OCL (output capacitorless) configurafion. The benefits of this type of circuit are very widely recognised and may be summarised as providing unrivalled transparency, speed and dynamics. A small amount of feedback (6dB) is used to allow the GM 20 to drive even difficult loudspeaker loads without problems. As can be seen from the attached specifications, the performance is of a very high order. For example, the bandwidth extends from 1 Hz to beyond 35OKhz!
As befits an amplifier of this class, it is possible to use the two inputs L and R in balanced mode by means of XLR plugs or in unbalanced mode via RCA phono plugs.
