Identifying company logo font (Technical Audio Group)

[Michael Goodyear]

Hey,

I've been asked to tweak this logo but can't find the original font, nor can the company.

Any suggestions?

 

Cheers

Ah! I wondered if it was a variant (due to the differing "a" and "g"), but it's clearly too close not to be! Thanks!
