Hi,
today I wanted to check if the tubes of my road king series II were matched using the oscilloscope and sine generator method.
Accidentally the generators output was set high in level which I did not notice. After all my measuring job , I wanted to try the amp and noticed that I need to increase considerably the volume (output) of channel one to have the same amount as before.
What strange is, all other channels are ok, it' only the clean channel. I already changed the 1st tube, thinking it might come from there , but nothing..
Any suggestions where to look.... ?
Thank you
Pino
