    So my Blues cube hot died last night... No mains light, sound, nothing. Had chassis out... No burn marks, internal fuse intact, different mains leads tested. The main problem is I'd sold it locally. The guy gets back to me an hour or so later saying its died. Its been fine, albeit very susceptible to buzzing and sensitive to bad mains / tube lighting. Any views or comments welcome guys

    In old vernacular...bummer!!....for the buyer and you. This is one of the problems when selling or buying used equipment.
    was it sold ‘as is’, or did you give a warranty or return policy??? Did the buyer cause the failure somehow??? First of all....is the fuse good or does it simply ‘look good’. A failed fuse can fool the eye, ime.

    I once had a fellow interested in a Rivera era Fender Princeton Reverb II. His wife was adamantly against his buying it because she thought buying a new Hot Rod Deluxe/Deville type of amp with..at that time...a 5 year warranty was the way to go. I had known the Prin Rev II for 6 years, and it had never given a problem. He wanted a warranty....I offered him a 30 day warranty at the asking price, which was less than the new Fender amp. He came back and wanted a 6 month warranty. I agreed to that for an added $100....still less than the new amp. I observed that what was going to happen is that I would simply make $100 more on the deal and that the amp was going to be fine. I also observed that he was going to need the warranty on that new Fender because ime the failure rate on those inexpensively built newer Fenders was higher than with the older handwired amp. Note: I see far more of these inexpensively built Blues/Hot Rod amps failing than I do vintage amps that take a dive. He kept coming back with other ‘offers’ until I finally told him that I did not think that the PRII was the amp for him and I was not wanting to sell it to him. He was a winter ‘snowbird’ from Connecticut...his wife drove a Bentley. I was glad not to sell it to him as I was sensing nothing except trouble from him....or more specifically his wife.
    Good luck with the situation. I vote that the sale was ‘as is’....and that operator error is as likely as any other cause. If you have a spare fuse, perhaps that will get it back in operation...or check the fuse with an ohmmeter to ascertain if it really is good.

    What was he doing when it died?

    In his shoes, I'd wonder what you did to sabotage the amp.

    In your shoes I'd wonder what he did to sabotage the amp.

    Fuse is where I'd assume got hit by a spike. Maybe if that's ok a spike hit before the fuse, and I've never contemplated replacing a SS power anything, so I'm not sure what that entails.

    I once sold a college kid from OU(notorious party school) a mustang bass. He texted me 6 months later a picture of it in the case and a story about it surviving a venue catching fire. He was confirming what I told him about fenders being hard to break......

    I have some old SS Peaveys for sale on this side of the pond. Not nearly as good at faking crunchy tones, but cleans for days and almost impossible to break....

    re: old Peavey.. I agree that they can be hardy amps. I kept an ‘Extended Range Musical Instrument Amplifier’ model for: the ‘70’s around for a long time because it was a good test bed for anything......guitar, bass, keyboards...anything. I was playing through it one day and it went silent. I am sure that the filter caps gave up the ghost, but I have not repaired it. it would be an act of love since it would not bring the price of the repairs....but it is one of the best sounding old Peavey SS amps that I ave been around.

    Thanks for the 'constructive' comments guys... I won't try another fuse incase there's an underlying problem... I'll get it looked at first.

    Ime, one more fuse will not put the amp at risk as long as the fuse is the proper rating. An ohmmeter, which imho every guitarist should own since they are so inexpensive and so very useful, would tell one in a second or two if that fuse is blown or not.
    So...you took the amp back?

    and...imho...our comments have been constructive.....as opposed to being ‘constructive’. I’ll log that response in for future consideration. (;^)

    Yes I took it back as the guy was a friend of a good friend, not some random guy... Log what you like mate. I put 'constructive' because like most forums, you get actual constructive comments like most on here, but also like most forums, you always get the occasional unhelpful Smart ass.

    A thread on another guitar related forum (starts with Gear) had a Blues Cube which experienced the same failure mode as the OP has described. It ended up being a failed power supply.

    How well do you know the guy? Be sure it's the same one you sold him.

    May be a bit old, but I had the power supply fail on both my Blues Cube Artist and my Blues Cube Hot. I bought both of them used, so no warranty. It cost me $275 to replace the power supply on my Blues Cube Artist at my local amp repair place. I only paid $500 for it with the GAFC foot switch, so it was still worth it. The good news is that since I had it repaired almost two years ago everything has worked perfectly, which leads me to think that the original problem with the power supplies has been fixed. It may be my imagination, but the amp sounds better after the replacement as well. The The Blues Cube Hot is sitting in my basement while I ponder whether or not to pay for the repair. Since reliability is one of the big selling points, I'm a bit vexed to have two out of two Blues Cubes fail on me.
