I have for sale a very high end preamplifier, the NAT Plasma, from the Serbian company NAT. Their stuff outperforms the competition at their price level and quite a bit beyond. The Plasma is truly dual mono with dual power transformers and even dual, tube regulated high voltage supplies! That's right, each channel has its own regulation. The output stage is 6 PCC88s per channel (I think in parallel) and all are NOS of highest quality (Tesla and Telefunken). The output coupling capacitors have been upgraded to Jensen PIO and VCAP PIO (paralleled together). The preamp is in excellent working condition and very good cosmetic condition (no scratches on the front only a few minor ones elsewhere). The sound is powerful and resolved with a full, but not overly warm, tone. Strong dynamics are guaranteed as would be expected from such a robust power supply and multiple tubes in parallel. Really excellent sonic quality and holds it's own against much dearer competition.
Note: It is a 240V preamplifier so for use in the US a step up transformer would be needed. I have a very good box for shipment but no manual and the preamp does not have a remote control.
