I have a 25b and its a pretty decent exciter for the price it has a digital tuner so your not playing with a tuning pot to get tuned onto the broadcast frequency. The unit also has a jumper so you can force the exciter into mono if you don’t want stereo.
The only complaint I have with it is when its finding lock you can be listening to any station on your receiver you will here it sweep (which produces momentary interference on the station your listneing to). Once its locked though its rock solid with practically no drift. The other thing is the hum I am using a regulated power supply on mine and it still hums its not very noticable when music is playing but its annoying to know its there I’m going to attempt to get a metal case for mine and see what happens.
Most likely most of the hum is due to the plastic case a metal case blocks the RF waves from re-entering the circuit which causes most of the humming this is called RF feedback.
