Nokia Dolphin amp modified as per Rob M0DTS web instructions. With input filter and manual switch for bias on/off with indicator LEDs. Dual fans on a variable power supply and another one for the 12 volt supply. Can be fully driven (or over-driven) direct from a Pluto and provided a reliable solution until I built a bigger amp. Comes with a XT60 connector pair for 28V. The RX pre-amplifiers were removed for my own use elsewhere. £80
Can take to CAT24 or delivery at cost by your chosen method.
