It's collection only, so while I'd love a backup to my BT5110, the best I can do is pass on this deal I've spotted.

Ninety quid for a 500W amp, removable head, 250W in the 1x10" combo. I've had mine for over 11 years and it's been fantastic - the only thing which went wrong with mine was the headphone jack needed replaced a few years ago.
These are fantastic amps and don't turn up very often. Hope someone snags it soon, ninety quid is a steal for this amp. 1 year warranty too.
