    vox ac-10 layout but actually drawn out/former frankenstein project

    Hello all, A while back I had done a frankenstein like Vox AC-10 in an AC-15 chassis with limited success. Sure the Normal Channel worked but the Ef86 didn't and that irked me quite a bit. Eventually I went and decided to get an actual AC-10 chassis and start transferring the guts from one...

    vox ac-10 debugging/ ef86 vibrato volume lower than normal volume

    Hello all, Something I've been trying to figure out this week but is confounding me. I've been further debugging my vox AC-10 amp and I have run into a bit of a head scratcher. When I turn up my Volume knob on the vibrato channel I have to have it all the way up before I can hear it whilst...

    Vox ac-15 Output Transformers...8k vs 6k

    Hello all, Been looking through my vox schematics AC-15/AC-10 and they are listed as 8k for the primary for the OT. In fact I built my Vox AC-10 using a 20 watt 8K primary OT with multiple taps. In fact it is an upgraded 5e3 OT that I used just because it matched the specs from the schematic...

    9 pin socket center pin, maybe a foolish question

    Hello all, Foolish question for the hive mind. On a 9 pin tube socket their is a metal pin in the center of it on the bottom. Now is that a ground lug or is it just a tie-point? Just something that I would ask everyone as I further debug my amp project and wanting to move a few grounds to a...

    vox ac-10 schematic question/filament grounding

    Hello all, Still debugging my vox ac-10 amp as I found a few more mistakes that I had made while building it. I did notice one thing along the original schematic and that has me scratching my head. I'll post the original but if you look at the schematic you see on the filament string you see...

    Foolish question...maybe. The wiring of a 40-18079 Vox AC15 Power Transformer

    Hello folks, Possible foolish question here but it feels like a real head riddle. A while back I wired up my 40-18079 Power Transformer up in my Vox Ac-10 Frankenstein of an amp. Where I've finally caught up on many of my amp projects this is my last one that I want to finish up for a while...

    vox ac-10 build in a ac-30 chassis, set up to be able to do 15 watts...21st Century Voxy

    Ma Sonic stereo amp schematic, question

    Hello all, I have a question about series string amps. I gave myself a challenge of doing a stereo amp based off of Tino Zottola's Ma Sonic 1 amp with the exception of me wanting to use as a low powered hi fi stereo. It can be used a low powered stereo guitar amp if you wanted to change a few...

    How do you do power transformer calculations?

    Hello everyone, Question for anyone who can explain this to me as I haven't found any place that can explain this simply. My google-fu has not yielded me any places that can show me what's going on plus my attempt to send a letter to Merlin Blencowe has failed also, hence me asking here...
