If a in depth course was given on repairing tube amps then every aspiring new tech should be made as part of the final machanical / electrical part of the test to change out the 3 filter cans in a Ampeg V4 or Vt22.
Just sayin after doing another one of these darn things!
Lol!
Who else is on board with me on this?

When I die, I want to go like my Grandfather did, peacefully in his sleep.
Not screaming like the passengers in his car!
Cutting out a man's tongue does not mean he’s a liar, but it does show that you fear the truth he might speak about you!

Re: Required training
By strange coincidence I have recapped both a V-2 and a V-4 in the last six weeks. Along with power cord replacement.
I didn't find these jobs to be difficult at all. If there's a skill qualification test for an amp tech to pass before becoming a "Real Amp Tech", I'd expect it to be harder than that!
The qualification test should be an amp that has one puked filter capacitor, two shorted coupling capacitors, a riveted-in tube socket with hogged out contact pins, a failed FET in the channel or loop swiitching circuit, a broken chassis ground wire underneath the PC board and a parasitic oscillation caused by bad wire dress.

Re: Required training
did v4 restauration, complete , removed all the wires, components, cleaned carbonised pcbs , reinstalled al new, painted chassis new etc, one month job 
Re: Required training
Should be a nice amp after the restauration !
But lots of work.
I love those, especially the « Distortion » models (even if you don’t want to use the Distortion channel).
