The Firestone audio mass pre amp i bought from new about three months back to partner with some mono blocks
i sold the mono but kept the mass thinking i would buy some valve mono blocks,maybe will in the future.
The thing i like about this pre amp is the volume is very fine so you can adjust the volume better then any remote control amp i have ever used.
£90 which includes delivery.
i have the box still and it comes with a psu pictured (DC24V 0.5A power adapter)
i am away from the 10th for sometime so if they do not sale i will need to remove them for sale as i will not have access to the internet.
