Astro Spectra with HHCH Requires Head Swap

[MTP300]

Hi there,

I have a couple of astro Spectras that have no HHCH units, is it possible to convert them to a more conventional head? If possible whats involved, will an older non-astro head work I wonder?

Can anyone shead a light on this for me?

Best regards Steve
