A British guy named Grusvenor has published a complete guide to servicing Vox amps, containing never-available-before diagrams, layouts and schematics.

Young Stuart! The man!

Please correct the tremolo to tremolo ....
@ralphj4012
Odd, as you say, that all three tracks were going nowhere. PCB board to board fingers never soldered properly from new, perhaps (and a design accident waiting to happen).

The AC-30 is my favorite Vox model. It is a shame that the factory Q.C. was horribly irresponsible. Great job getting it sorted, Stuart. I admire your sense of saving the customer a possible 75 quid for a full exploratory. The mod worked well. Thanks for posting. Cheers!

Great work Stuart.. I think Vibrato & Tremolo are great effects to have built into an amp and I'm sure the customer will have been delighted that you managed to fix them at a sensible cost. You can get a very adequate trem pedal for £20 theses days so I completely see your point of accounting for the time/cost/value equation her. It works now.. Job done !
@VegasCyclingFreak
Not to split hairs but it’s actually a tremolo, not vibrato 😉
@bluesplayer59
Splendid as usual 🎉
@waynegram8907
STUART, Why does reversing the output transformers Primary winding will fix power amplifier oscillation problems?
@daffyduxxx
Makes you wonder what happened to quality control at the manufacturing stage.

Hey Stuart, a bit of pest that one..Love the way you get around these nasty little faults..Great job as usual..Interesting video..Ed..UK..😀
@paulsto6516
Jolly good!
@jutukka
You must fill that amp with helium first. Then it's easier to lift. 😂

I only have a VERY Basic understanding of this stuff, so pardon me for asking........... What was that "Hum" trim pot adjusting.....
@74cannelle
Why did they use a 6 positions rotary switch for 3 speeds available ? Maybe (if it would have been connected) would it make different configs of resistors to achieve 6 speeds ? We’ll never know.
