I am selling this beautiful 312B-4 as is, as described for a client who is planning to sell his home and has to down size his collection.
This collection in particular has the nicest and cleanest Collins gear collected over many years. I checked this unit on my bench to make sure the speaker works and mutes the audio.
I also checked the wattmeter functions. Everything looks to be okay and the wattmeter is within spec and reads acurate. I did not check the phone patch or other switch functions but everything appears to be in good working order.
