You would need to cut off the original 2 pin connector and splice it onto the new fan cables, observing polarity.
I... er... cough ... have been known to 'fix' them by putting WD-40 into them, if it's too much of a hassle to replace them for a quick job and/or the customer doesn't want to pay for a new fan. You need to get enough of it into the gap between the rotor and the frame that it will reach the bearing. The motors are brushless so I don't think it can do any harm, and it does seem to work as a short-term measure - if the problem comes back you will need to replace it though, these amps totally rely on the fans in order to not cook the power ICs.
My personal opinion is that you should fix it any way you can and then sell the amp as quickly as possible...

Thanks for your opinion, I'll file it.
At least it isn't a Mode Four .

People get attached to guitars, but I've lugged that stupid amp around to some fun places and played some fun gigs with it back in the day. I'll never sell it.
And yeah, cheaper than I was expecting!
I've never actually seen another one like mine. It's green. And doesn't have that big awful Valvestate decal on it.
I don't think they're that bad-sounding either, but they're just quite a marginal design for reliability because of that fan-cooled power module - or two of them in the 275, which doubles the chance of failure.
Still, it's not as bad as the Mode Four, which has four of them and connected together in such a way as to not just quadruple the failure rate but almost guarantee that it takes out more than one at the same time... I won't even work on them, since I can't warranty them.

It doubles the chance of failure, but is it going to cook itself with one fan still running? If yes is the answer, it's a poor design, because if you have one fan and it's not working, you'll hear it. If you have 2, and one packs in, you might not notice.

Hopefully yours will hold up a bit longer!

On a similar theme my workshop test cabinet - and probably gigging cabinet, if I ever need one - is a TSL122 combo without the TSL bit .
