Valves plug into sockets, the power valve sockets are screwed onto the chassis plate, but all the socket pins are soldered directly to the relevant PCB.
The reverb module PCB is piggy-backed on the main PCB. The main unit PCB holds the pots, pre-amp circuit and two 12AX7 valves, sitting in a horizontal position, one under the Gain pot, the other between the Reverb and Volume pot. The power valves hang upside down right behind the speaker magnet, on a PCB separate from the main unit, attached to a bent-out section of the chasis plate. The construction is weird: The chassis is an “L” shaped plate, screwed to the cabinet on top (two screws) and to the back cover (nine screws) for support. The owners posting on the internet are almost unanimous in praise for this low-cost (?) Chinese PCB semi-hybrid amp. This amplifier is well documented.Īlso visit “The VOX Showroon”, hosted by North Coast Music, for infornation and pictures: “VOX AC10C1 Amplifier Under the Hood”. I did get some good information off other pages as well, where tech-minded posters gave information on the silicon stuff and circuit design. I refer you to TDPRI, where there is a 40+ pages thread on this amp, under VOX AC10C1 owners club. I have not yet measured wall Voltage here, but it would be the usual 240+ VAC, thus the amp will be running hot. Gain, Bass and Treble controls, Reverb level, and master Volume, claimed 10 Watt output. Specs – Vox VX 10 (Celestion) speaker (16 Ohm), two 12AX7 valves in the pre-amp, two EL84 valves in the power amp. The amp can get very Boomy as well as very Ice-picky. With the Gain low, the master Volume does not really make the amp louder above about 2 O’Clock. Would be fun to evaluate at higher volume levels.

Turning the Gain up to 3 O’Clock, I can barely crack open the master Volume, sounds OK for slightly fuzzy/distorty sound. (The faceplate is not numbered.) This is with DiMarzio PAF 36th Anniversary humbuckers and a DiMarzio Red Velvet single coil in my Ibanez Jem Jr, with guitar volume around 5/10, tone 3-7/10. I normally play with the Gain at about 8 – 9 O’Clock, master Volume at 12 O’Clock, and have settled on Bass at 8 O’Clock, Treble at about 09:30, Reverb at about 08:30. I am currently using it in a small-ish bedroom (3 x 3 ½ meter), and cannot evaluate it at higher volumes. 10 Watts? It also has an abundance of low-end. I bought it having no VOX-sound experience, and internet research indicated that it should be a fun amplifier. My ex-wife commented it is a good-looking amplifier. I bought a Burgundy VOX AC10C1, during Black November 2020.
