MikeC Sixty-One SRT
After seeing the video I had to build one - my take of the Vox AC10 SRT which I'm calling a Sixty-One SRT https://www.youtube.com/watch?v=alBO_yEn5o4.
What an awesome sounding amp and my plan is to make this a combo.
I found a schematic (with errors) and created my own layout which I built on a pre-drilled turret board. This is the prototype.
It's not very tidy but v2 will be.
Tonight I got it going with tremolo and (some) reverb - I'm quite stoked.
Now the modding and tuning begins!

Re: MikeC Sixty-One SRT
Far out, am beyond excited with this build, may be tempted by a non-reverb and trem version if that will be in the works at any point?

Re: MikeC Sixty-One SRT
I suspected it would inflate your tyres JB! Removing the reverb is way easier than making it work - the original Vox AC10 SRT used their own reverb tank design which was essentially 2x ceramic cartridge transducers (i.e. from old stereos prior to magnetic cartridges) - apparently done so Vox didn't have to pay Hammond a royalty for their patented reverb tanks! I've got the reverb working with a "Hammond" tank BTW.

Re: MikeC Sixty-One SRT
Already designing the combo cab in my mind and thinking about 10" speakers

Re: MikeC Sixty-One SRT
Agreed, 10W clean, reverb & tremolo. Awesome when driven!

Re: MikeC Sixty-One SRT
IIRC the original doesn't have master volume, right? Any chance this one can have MV or some kind of power scaling?

Re: MikeC Sixty-One SRT
I don't know if I could part with my AC10 so maybe I'd have both

Preamp tubes are NOS 12AU7s except V1 (12AX7). Early days yet! Genalex Gold Lion El84's in the power amp.

Re: MikeC Sixty-One SRT
Correct, no MV. Global Power Scaling is already in the plan - see that joiner in the red wire - that's where I will scale the power amp section only. But gotta get the amp working 100% before I start the GPS experiments PS I tested the amp's power output this morning, it's around 12W RMS clean.
