Small BPC set found by the dumpster and back there again
Small BPC set (Baysonic I think it was) made in 1999 found by the dumpster so I grabbed it to play with. It had "snow" on the CRT when I turned it on, but no sound. Okay, maybe this is a set that mutes the audio if there's no signal present at the FM demodulator (like a squelch on a 2M handheld or a police scanner). Took the back off, and hunted around with another audio amp (an amplified computer speaker not connected to a computer), found some hiss. Then hooked up a video modulator to the set's RF input, and some audio to the audio and video jacks (couldn't scare up any baseband video at the moment). But the set went and died completely. Guess it didn't like the audio as video?, I thought sync circuits would just ignore the irregular pattern. Forget it, I pulled the main and CRT circuit board to salvage parts off of, and returned the cabinet with CRT back to the dumpster... You can get a number of high voltage caps usable for tube work from such sets.
