Ameco PT-2 Preamplifier
The PT-2 is a RF preamp covering 1.8 to 54 MHz. It is designed for a transceiver but works equally well with just a receiver. I purchased this preamp online and it was advertised as working. However, it's getting to be a rare day I ever get anything online that actually functions as advertised. I replaced 6 components to get it back in proper working order: three burned resistors (R5, 6, 12), two bad 1N4148 diodes (D3, 4) and the power supply electrolytic filter capacitor (C9). I upped the working voltage of the cap as the original was only rated at 16-volts, but the power supply voltage is 15-volts. I changed it to a 25-volt cap. Also, half the split shaft of the gain control was broken off, so the knob would not stay put. Hey, but otherwise, it was in perfect operating condition.
