Nice DDS amplifier! Time Owned: more than 12 months.
There are four of the WA1FFL - Jim Hagerty VFO Post-amps in my shack. I used two of them with DDS VFO's and two with Epson Oscillators. They are very clean well thought out designs. The parts in the kits came with clear concise instructions and numerous tips and suggestions. The parts came in individual labelled coin envelopes. The most important reason for purchasing these kits is the super nice circuit board. It is laid out very nicely with component locations labelled. I installed 100 k? pots in place of the normal 50 ohm input resistor (R1), with the wiper going to C1. That allows adjustment of the input drive to the amp, thereby setting the output for the best level and waveform. These amps are used to drive boatanchor CW & AM rigs. The circuit boards mount nicely into Pomona or Hammond type cast enclosures. An amp could have been fabricated on the cheap with a couple of transistors, etc., but this solution is so clean. I love these kits.

GREAT for boat anchors Time Owned: more than 12 months.
Easy to build and works like a hose! I have used this amplifier with the FCC 1/2 and the DDS-60 and it works great for driving the Central Electronics 10 and 20 series exciters. what more can I say, it works and works well, output looks great on the scope.
