Cap replacement

[tubesornothing]

Howdy gang... it has been a while!


I am repairing an old juke box amp for my brother.  The elec caps are old so I am going to replace them.  By matter of course should I replace all caps?  coupling caps, etc.


thanks!

got schematic, pretty comfortable inside tube amp?

me, I always like to just plug 'r in and go from there 

if nothing flames out, I get what data I can then build a game-plan from that

to your question, depends;
vintage, keeping it original, then No
hacked a million times, rebuild it new n someones kids can fix it when they are your age

Probably, especially the old tubular wax coated paper caps. Some caps can stay. The domino caps are usually OK. Show us some pics. I'll show you the ones I would replace. Are you restoring the jukebox or just gonna repurpose the amp?

Hey Sluckey - long time.


Here are some pics of the amp and the tormat unit (for song selection).  We are rebuilding the jukebox, so not re-purposing it.  Has some noise issues - maybe some Dc on the pots.  A few scrathy post  No motorboating or anything like that.    For some reason, in the Jukebox circles, its a common thing to recap the whole unit.  But around here - with guitar amps -  it usually only when necessary.

I would approach this from an evaluation and troubleshooting standpoint, rather than just wholesale replacement.

Yeah - I think that way too.


thanks
