Re: Blues Deville recap
I'd take it to a tech if you can't test the caps. Some of the ones you wanna replace may be okay?
Have you put them on a capacitor tester and checked them?

Re: Blues Deville recap
a capacitor checker is a modern Digital Multimeter
the same ones they sell at Harbor Freight for $5
remove one leg from the circuit
and test it
if you dont have a capacitance test on your meter set it for ohms
you will see the resistance count up or down, depending on the orientation of your leads
when it ticks to a point it will "reset" and start over
resetting is when the cap discharges ( be careful )
the voltages inside the amp are very dangerous
*******
the caps can hold a charge long after the amp is unplugged

BE CAREFUL

Re: Blues Deville recap
That's why I suggest a capacitor tester with alligator clamps to hook to caps.
Either that or discharge caps first. You can get hurt really badly using a multi meter to test caps with if you don't know what you're doing.

Anytime I hear this I think of when I went to AIT in the Army. Was a school for satcom operators and we learned electronics from the ground up. It became a common joke for someone to charge up a capacitor then huck it at you and yell "catch!" or "think fast!" You learned very quick not to catch anything that was tossed at you. Good times. :knockedou

Re: Blues Deville recap
you can't test it with it in the circuit, in either case
but the caps really don't go bad that often
my buddy had his Twin re-capped and tubed by the famous Mr Langraf 20+ years ago
he has played it 4-5 hours a day every day
gigged it several times a week for years
it still sounds great
