The Paesano Receiver RF Amp Stage

This is anther one of my more or less standard deisgn and gives about 12 dB gain over most of the HF Ham bands. See the Note That R2/R3 is a 100 Ohm Trim Pot.

Shown in the third photo is the actual hardware. In the foreground center you can see the two 10 Ohm resistors in the emitter circuit. Note the heatsink -- this amp is biased HOT. There is an additional 100 nF cap connected to the center wiper on that trim pot. It is not shown on the LT Spice simulation but is installed in the build which is seen in the lower right hand corner.
