mswanson65 Posted December 4, 2018 Share Posted December 4, 2018 Hi All, I know there are some JM Blueberry users on here so I thought I would post this. Mine just seems to have died. All I have done so far is 1) put back original tubes, 2) replaced the fuse and 3) tightened the screws on the football shaped thing. I contacted Craig at NOS Valves but he is too backed up. So does anyone know of someone who can fix these? Any help would be much appreciated!! Happy Holidays! Mike Quote Link to comment Share on other sites More sharing options...
Schu Posted December 4, 2018 Share Posted December 4, 2018 Did craig refuse to work on it or would it just be to long of a wait for you before he could get to it? Quote Link to comment Share on other sites More sharing options...

Thaddeus Smith Posted December 4, 2018 Share Posted December 4, 2018 I've heard you can do the "9v battery test" with tube amps. Remove all tubes, turn on amp, then stick your tongue on the sockets to make sure they're still sending juice to the tubes.. Quote Link to comment Share on other sites More sharing options...

Mike Do you have access to a good tube tester? Another thought, is it a slow-blow fuse in there? Perhaps another fuse would be a cheap possible fix.

Hopefully they're close enough to you that you can avoid having to ship them which is always a risk with electronic equipment that uses tubes.

mswanson65 Posted December 20, 2018 Author Share Posted December 20, 2018 Thanks all for the great comments. I just wanted to provide this update. I ended up double boxing it and sending it off to RHB Sound Dezign in PA on 12/7. These guys are pre-amp mod and repair experts and sell their own line of high end pre-amps under the Backert Labs name. I got it back today and it sounds great. They had to replace a faulty bridge rectifier to bring it back to life. They were great to deal with, reasonably priced and very knowledgeable. Highly recommended! 2 Quote Link to comment Share on other sites More sharing options...
