First time poster here!
I am a long time L6 user and love the products. I have a SV MKII HD100 amp head that I bought used, just over a year now and when I power up none of the tubes light up and no sound to the Marshall 4X12. I've noted several similar issues posted on the fourum but none mentioned that the tube are not glowing.
I have not tried to see if the direct signal works, but will check that next, to see if it works.
I'm no techie, just looking for some info on what may be wrong...tubes, transformer, fuses (the fuse on the outer box is good, I don't know how to get at the internal fuses).
Any and all info appreciated.
