T&T x Vox AC15C1

This is our take on one of the top selling amps in the world, the Vox AC15.

The AC15 is a great amp straight out of the box, it comes in a hefty plywood cabinet, a Celestion Greenback speaker & quality circuitary on adouble sided PCB.

To improve on this strong start, we took inspiration from Lyall Cadwell (‘Psionic‘ audio channel on YouTube) and implemented some of his ‘Psionic’ mods. These included; changing the power filtering to the vintage AC style to improve playing dynamics, adding the ability to switch between the vintage & modern tonestack via a push-pull ‘Top-Boost’ volume control, & rebalancing the ‘Normal’ output to match the ‘Top Boost’ channel.

One major feature we felt is missing from the AC15, is being able to easily jumper the ‘Normal’ & the ‘Top Boost’ channels together, so we’ve added channel jumping via a push-pull volume control on the ‘Normal’ channel *.

As part of the usual T&T rebuild/refurbish, we upgraded the power filtering capacitors to top-quality Nichicon, preamp/signal film caps with Panasonic, & our favourite Nichicon ‘Muse’ bi-polars for the cathode bypass caps. Signal & power resistors were also upgraded to 1 watt or greater Vishay metal film.

To minimise the noise floor, wiring has been dresssed & re-routed where needed, shielding added to the back of the cabinet & the wiring from the input to V1 covered with a grounded mesh.

Finally we added a little bit of bling with some custom made gold vents to replace stock plastic/black ones & updated the handle & protecter screws to match.

The T&T x Vox AC15 comes with the stock Celestion Greenback, however we did get our hands on a mint condition Vox/Celestion Alnico Blue speaker, which is available to upgrade with.

Other included accessories are a cover and dual footswitch controling the Reverb and Tremolo.
