Vertex VX2000 - faulty internal speaker

[g8tzl2004]

I have just acquired a VHF 40 channel VX2000 but unfortunately it has a faulty internal speaker. Audio is distorted and muffled. The radio looks like it has never been used so I guess it has had this fault from new?

I have connected up an external speaker using the 3.5mm socket on the back of the radio and the audio is OK - so I guess I just need to replace the internal speaker.

I've checked the service manual but does anybody know where I can source a replacement speaker. Since Vertex was acquired by Motorola, I guess old spares have long since been discontinued or will probably cost too much anyway. Does the earlier VX1000 use the same speaker?

Thanks

I also noticed that the AF audio amp gain is way too high. It only takes a very small turn of the volume knob from switch on for the audio to be at the "correct" level....then any further small increase makes the volume too loud and a further small increase then results in "audio feedback" from the external speaker (NOT internal) on white noise. The speakers (both the faulty internal and 2 good external speakers) go into feedback at around 25% of maximum volume. At switch on, its impossible to get the "correct" audio level without a signal to monitor as it falls within a very small window...slightly too high and you are getting feedback. Looks like I've bought a pile of junk

I guess the low (and distorted) audio from the faulty internal speaker has maybe resulted in a previous owner attempting to turn the AF audio gain up in order to get "louder audio"....not realising that the problem was a faulty speaker to begin with (I presume)?

Any ideas?
