A super clean Vox AC30TBR (Top Boost, Reverb) 'standard' amplifier produced under ownership by Rose Morris, made in England (1991).
From my research, this was one of Vox's successful attempt at reclaiming the glory of their 60s models, closely mirroring (though not identically copying - plenty of info regarding this on the internet) their original circuits. Notably, this variant was denoted the AC30TBR, with TBR referencing both the inclusion of a Top Boost channel and an on board reverb tank (in this case, a USA Accutronics pan as standard).
The AC30TBR models of this period were produced in Wellingborough (Northamptonshire) by Precision Electronics, who won the contract from Vox following a string of volatile partnerships throughout the 70s-80s. I believe the general consensus is that these models were the first 'good' Vox amps since the 60s.
This one comes with excellent provenance, having been purchased new from Rose Morris alongside a Rickenbacker guitar in the early 90s. Not taking to either, the amp has sat near untouched for the past near 35 years. As such it provides somewhat of a time capsule example, with little in the way of wear or marks and is running smoothly and issue-free.

Condition:
As above, this is likely the best example of this model in the best possible condition out there! One careful owner since purchase new at Rose Morris in 1991, sat unused for near 35 years. As such it's playing wonderfully and is entirely original. I would probably recommend a light service, simply owing to the fact it's sat static for 3+ decades. But to my ear, it sounds very good indeed.
Modifications/repairs:
Full Coopersonic service.
Strictly collection in person only on this one - these are rather bulky amps and as beautiful as it is, it’s not my primary so I’m selling it for a bargain price to make some room!
