Maybe you can replace the broken modulator by one of an old VCR.
Or try to repair the original. Most modulator are based on a IC, like LM1889 or something similar. In this case if the modulator is broken, sure the IC is the cause. -

I've just noticed they say and the FAQ says the +2A was made in Hong Kong and the +2B was made in Taiwan. Isn't it the opposite? The baud rate of the spectrum is 1500 not 1200. There's some interesting talk on faulty ram chips and holding back the 128. -

I think you're right there. My +2B was certainly made in China. The tape I/O is listed as 1200 baud in some places and 1500 in others. I'm not sure which is true... And that RAM chips thing was certainly weird - very inventive, our Sir Clive! -
