DIY AC15 tremolo not working

[havazli]

Hi everyone,
Just builded Vox AC15 with (normal-EF86 and top boost channel) with added Vox Pacemaker tremolo.
Schematic : http://i1072.photobucket.com/albums/...ps9psjlgnj.jpg
The amp is working and the sound is amazing,but the tremolo is not working in any way.Checked several times for errors..No way.When the tremolo is "on" there's near 70v drop in overall amp voltage.The sound is somewhat blocking distortion and the volume is too low..Any advice and suggestions will be greatly appreciated.

DC voltages would be helpful here... especially on the red dot. Still, I'll take a guess.
Check that voltage with trem on/off. Any significant change (more than a volt) indicates a problem - possibly with the .1uf coupling cap from V2b.

I would say check for proper ground connection on depth pot.
