SIf memory serves correctly that is a Cybernet chassis radio so you may be able to find another older 23 channel CB with a similar Cybernet board and transplant the parts you need. This may be a practical idea with parts on hand. Someone please chime in if I am incorrect about the Alaron B1025 having a Cybernet board. I do remember the Alaron's had a very nice microphone and I and using one on my Pearce Simpson Pussycat 23 Base Radio.
