Update:
I have been speaking with the distributors (Synergy) for the last couple of days (recording ALL conversations on my mobile phone... muahah!!). The guy said after he spoke to me for the 1st time, he picked the amp up himself from the shop in question, and took it back for a tech to look at it.
Spoke to him again today, and the amp is with a tech, and is assumed to have been fixed, something about a faulty tube actually blowing and shorting out a circuit in the ENGL (i think its the Power Tube monitoring circuit, but not sure).
Apparantly, the amp will be taken from the tech back to the shop today by around 4pm... not really looking forward to phoning them up to ask when the amps going to be back with me..i get the feeling they wont be too happy with me for basically side stepping them and going to the actual distributor!!
But hey, if someone is BS'ing me and fobbing me off i'm going to make sure i find someone else in a position to actually help!!
I'll name and shame them after i get a working amp back :P
PS thanks Elliot, i've noted those down incase i speak to the shop while i'm out and about today :)
