The triode section was used as a pre-amplifier, while the pentode section was used for the output. Since I only had a four-terminal strip, I decided to tie one side of the filament, one side of the audio output, and the B- all together on one terminal, which I labeled COM (common). This method eliminates the need of extra terminals and works nicely. Note the polarized plug, this is important to prevent the possibility of being shocked from the terminals. I highly recommend using this with an isolation transformer or figure out a way to get everything contained in a single box without exposed power supply lines!
The amplifier works very nicely and a quick test of the amplifier's sensitivity is by touching the audio input to produce a 60-cycle hum noise at the speaker. It could be used as a crude signal tracer for troubleshooting radios.
