Hey guys,
Tonight I fired up my Jolida 202 (Not "A") for the first time, with a used (hardly) matched quad of JJ EL34s and some brand-spankin'-old (NOS) 6N1 and 6N2 driver tubes.
However, I am hearing an odd sound, from the tubes, not the speaker outputs.
It's best described as being akin to the sound of a rolling boil (water). Is this just the sound of new tubes being broken-in? Or is something amiss....
I don't remember hearing this with my LD III. :/
FWIW, it's being burned-in driving a pair of 8-ohm power resistors with continuous sine waves from a function generator.
NK
